  1. OK I will go first. Got some bloating and constipation but it wasn’t bad. I cut back from 4 pills to 2, I was amazed It still works as good as the 4 but it does. Also got some toe and ankle cramping but I also twisted my foot mowing the lawn so I’m not sure. I thought it might be the arginine? Maybe? For me the good outweighs the bad.I feel great!

    • Matt, did you notice any difference at all by switching to 2 pills? I read what you wrote on the original review. I am your age and noticed everything you noticed. It was overnight. The next morning I felt rested. Aches and pains gone. Great recovery with exercise (I take no other supplement). Nearly 3 weeks in I feel like I felt in my 20′s. No side effects at all. Wow, it’s pricey, though. If I could get the same result with 2 pills…that’d be great. I’m 5 ft 9. 155 (153…lost 2 lbs…and I NEVER lose weight).

      • Aaron, I cut back to 2 sometimes 3 or 4. Really its still about the same. I lost probably 7-8 pounds over 3 months. I’ve noticed that since recovery times are so quick that you end up working out a lot more. For me a lot. So I’ve gotten some gains in muscle I don’t think I could have attained without the gf9. Glad its working for you. Another poster said she felt like some body chemistry’s process the supplement better, I think she’s right. It would explain the hit and miss with some. I’m thinking about trying deer antler velvet pretty soon. Reply back if you feel like it.

        • Matt, I tried switching to just 2 pills and it didn’t work for me at all. It was like not taking any. Oh well, I had to try it. I have been trying to figure out what I can stop spending money on so I can afford to keep taking it. This past Monday, GNC online had a 30% one day sale on nearly everything. I bought 3 more bottles @ $56 each.

          I have 8 days of pills left so that means I’ve been on GF-9 for 23 days (including 2 days @ 2 pills). I have just started to notice that my skin looks different. I noticed it on my hands first then my face. I can’t quite say exactly what it is that’s different…it just looks…healthier, maybe? Smoother? I can’t put my finger on it but there is something about my skin that just (last Friday I noticed) looks…different…better.

          The lack of aches and pains; the good, non-jittery energy all day; the sleeping better; the waking up and feeling ready to take on the day vs. feeling like I’ve been hit by a truck. It’s profound. I don’t know that I have ever felt this solidly good. I think I can do $56/mo. I don’t think I can do $99. Also, my significant other says I’m easier to be around (I didn’t think I was difficult BUT…) so maybe it has affected my mood, too. She is so impressed she is going to try it for a month. I have also stopped drinking as much coffee and I don’t drink it for the caffeine, I drink it for the taste (black). I have not had nearly the desire for it…weird.

          I have noticed that I don’t have the aches I usually have during and after exercise. I am keeping more muscle and slowly losing fat. Tried on pants I haven’t been able to get around my waist for 2 years and they fit perfectly. This just keeps getting it seems. Fascinating.

          • Your description sounds like what happened with me, exactly, even the bit about the coffee. I decided to take a break from it after 2 bottles. I am taking buckpower now, red deer velvet antler from new Zealand and I’m pretty impressed with it.

  2. i started getting frequent cold sores (from the arginine) and my husband has suddenly developed Gout

    How long do you need to stay on this product.

  4. How dangerous is this product to the elderly?

      I have high cholesterol. I read that hgh, Serovital as a side effect can cause high cholesterol, tumors and diabetes. I am 71 and in good health and I’ve been on it for almost one month and feel good so far but no noticeable changes except my backache has diminished and my appetite has decrease. I lost 10 pounds in three weeks. What is your opinion re the side effects.

  5. I’m really wanting to loose 15 unwanted pounds yesterday. Will this product help me with that??? Thanks for any reply.

  6. Just want to say that it’s been six months; 4 pills per day and my allergies have NEVER been acting up so badly. OMG! The other day I did the nasal flush and it looked like a piece of the yellow plastic casing (that covers the pill) either came out of my throat or my nose and it was only partly disolved. GROSS! I do not know what other bacteria I may have contracted from these pills now disolving. It’s kind of scary. On the positive side: I my skin feels more supple. I still don’t know what the benefits are for a lower dose but I will have to think about taking these again.

    I have been on just 2 pills for about two weeks. Now I take the pills when I wake up around 5 and that is better. If I take it before bed time I cant fall asleep and have to take a sleeping pill. Don’t know if I should continue.

  8. I have been taking 4 pills for a month & 1/2, within the last week I have had breathing problems, lungs burn, coughing. Not sure if allergies are acting up really badly because of the hgh or I have a respiratory infection. Anyone else have breathing problems? I’m not seeing any good effects from this whatsoever. I’m 55 and very active, but I really don’t see any benefit from this. I will stay on it for a few more weeks and will cut it down to 2 pills to see if the breathing gets better.

  9. Have you ever had cold sores prior to taking this medication? Or is something brand new for you?

  10. I’ve only been on this stuff for a week. 4 a day, so far breaking out w/acne;(. Anybody experience this? Does it stop once your body adjusts to it? Grrrr:/. Thanks.

  11. I don’t think bacteria came from your pills. We all get exposed to many viruses and bacteria all year but especially in fall and winter. I’m sure you could have drank more water after taking the pill so it would go all the way down to your stomach.

  12. I have been taking 4 pills a day for 2 months. Very subtle results however I did notice belly fat slightly going down. I am 4’11″ and weight 105 lbs. After reading some replies. I will enter my 3 month by taking 2 pills a day. I was hoping for a stronger sex drive but basically is status quo.

  13. Just a warning for anyone thinking of taking Serovital HGH.

    I was turning 50 and noticed the hgh adds every where. I am fit and healthy and eat very healthy, but i wanted to go into my old age, lol, with a great start and the Serovital adds all said my body was depleted of hgh, so i thought why not give it a try. It was a bit pricey but ordered a month just to see. Well, the first week was great. I had the first great night sleep that i have had in a couple years. So far so good. Next week, i noticed my mood was better and a lot less stressed. Love it so far. The third week, i lost 5 pounds, i didn’t really need to lose, but almost everyone is happy to lose 5 pounds without trying! This stuff is awesome, so I tell my friends, you need to get this stuff! So i ordered three more months. Three months in i get HOT FLASHES FROM HELL !!!! These are coming every 15-20 minutes for 24 hours a day. Also sweating terribly. Figured its menopause, and it sucks, so there went my good nights sleep. Next thing i know, i get this burning sensation at night in bed, on my back, like I’m burning from the inside out, it is horrible pain, don’t know what it is. Couple days later, it moves to my front and its day and night. Then my foot has a pain in it, and i can barely walk, then my knee joints are killing me, then my hips, elbows, neck, my muscles are sore, everyday it gets worse. I didn’t even want anyone touching me, i need help just to get out of a chair. This is horrible pain every where. I have to take a leave from work. Went to doctor and he said my nerve endings are all fried and i might have fibromyalgia. I was so freaked out, how can this be happening, i was so healthy. Well, during all this, it was time to order more hgh, but i was feeling so bad, i figure why waste the money. I took my last pill. Then a few days later my hot flashes, thank God, went away!!! What a relief, they were intense. Then a few days later, the burning pain was easing up. I could walk again and move better. Then it came to me, maybe it was side effects of the hgh. So i went and researched side effects, and sure enough, all the symptoms i was having was related to hgh. Although my case it was debilitating. I was very angry at myself for letting this happen and at Serovital for having NO warnings on their website or info. I lost thousands of dollars of income by having to take a leave from work. I really thought I was taking a supplement or amino acid just like taking a vitamin c. I had no idea i was gonna to mess up my chemistry and poison myself. Everyday i get a little better, but still have very sore joints, i just hope and pray i did not do any permanent damage to my body. I don’t think this should be used without a doctors supervision and without a prescription. This stuff was toxic for me and i just want to warn people, if you get side effects, stop taking it immediately. I just think the company should put a warning out there that this is serious

  14. Hi, i’ve had completely different benefits from this product. What I’ve noticed most is that my finger nails are growing beautifully and are not peeling as they were. One of my favorite things is that i can sleep even after i have wine when i take this which i can never do otherwise (apparently it’s the glutamine) i did have some breathing problems but i started taking Claratin and that helped so i think i was correct in assuming it was allergies (leaves are falling here in the northeast). I wish i was losing a few pounds- not that lucky.

  15. I started taking this about 2 weeks ago and people have told me that my skin looks really good. I feel a burst of energy but I feel like I am putting on weight instead of losing. I have not changed my diet and I have been working out more while taking this and cannot understand why I feel like I am putting on weight.

  16. I have been taking the product for 3 months (4 pills at 6:00am) everyday. I haven’t noticed any real improvements such as the claims advertised. I haven’t had any noticeable facial wrinkle reduction or complexion improvement. I haven’t had any weight loss or increase in energy. I have experienced shortness of breath and watery eyes. I don’t think I will place another order/continue taking the product. I have not experienced the claims the advertising has made.

  17. I’m 73 and have been using Serovital hgh for 10 months, 4 pills a day. My energy level is better than when I was 30. My muscle mass and tone are still gaining. I have not lost any weight, but for me that is not an issue. I have also noticed an increase in sex drive. I have not noticed any bad side effects. I take it first thing in the morning, about an hour before I work out. So far, I’m happy with the product.

  18. I’m 52 and I am about half way through my second box, so far I have noticed my skin looks better, I am less tired in the mornings, and I can tell a difference in sex drive. I purchased SeroVital in hopes of helping with my facial skin, but I am getting other benefits, I also went to my eye doctor and I found it odd my vision had improved by a fairly noticeable amount, of course I don’t know if that has anything to do with the pills, but it did make me wonder. I ordered another box so I will take them for three months, hopefully I won’t experience the bad side effects some have reported. If I continue to see improvement, I don’t think the price is any worse then some of the skin creams we spend money on.

  19. i have been taking this product for 2 months now. last week a started having blood in my urine. Alot of blood. i have done nothing strenuous to cause this to occur. i went to the dr and they cannot find anything wrong with my bladder or kidneys. i am starting to think it may be a side effect of this product. Does anyone else have these issues?

  20. I’m 58 been taking 4 pills for 5 or 6 months experienced the following deep rem sleep with intence dreams both pleasant and nightmarish increased hair growth have to shave more often scalp hair is thicker increased feeling of well being I was always active but having more energy and less fatigue I gained weight but stopped smoking and may be increased muscle mass. Pant size and belly fat the same. My wife is on it too She just had blood work and her Hgh levels were ” normal” for someone her age 0.60 that can be as high as 8.2! She is now skeptical and considering stopping. She felt she had better sleep and like me had dreams but is questioning the $80 monthly cost

    I’ve been taking 1 pill daily for 3 weeks. I’m 60 yrs old and was just wanting quicker recovery from workouts and less stiffness in general, as well as feeling younger. For 2 days I’ve been having redness, itchiness and minor swelling around by eyes, mostly in eyelid area. Has anyone else had this? Before this happened a couple of days ago, I was about to increase my dosage to 2 pills daily. I’m not so sure now. It works well for me to take the pill in the middle of the night or very early in the morning when i generally wake up to make a bathroom run, so that i can have my normal coffee and small breakfast between 6:30 and 7:30AM. I can’t tell if there’s any difference in my sleep patterns, as I’m normally a good sleeper. I have noticed less stiffness, especially in my back when i wake up in the morning. Since no one here seems to have reported the eye irritation, I’m thinking it may be from something else? I may discontinue the pill until my eyes feel normal, and then try it again. I would love for this to work!!

  22. I only took three packets and my asthma, which had long lain dormant, suddenly emerged again. Coughing, chest congestion and now sinuses are going crazy. Is it serovital or a coincidence?

    I noticed better well being, nothing else but gained some weight. Took it for 4 month.

    I have been taking SeroVital 2 pills before bedtime for 3 weeks.
    I have terrible nightmares, bad dreams that I never had before. I do sleep well otherwise. I heard those nightmares go away after a while.
    My joints have started to ache, arms, legs and hips and I was wondering if that is a side effect.
    I do have more energy I think, no other changes, yet.
    The aching joints is what I am concerned about.
    Hot Flashes every day at the same time is a another symptom I did not have before. I never suffered from hot flashes. I am 69 years old and active and in fair to good shape.
    I will continue the pills until they are gone and hope it does not mess up my system.
    Does anyone have the answer to the side effects I experienced?

  25. Since taking this my cholesterol jumped 30 points, my glucose 10 points. I am out! No more for me. I exercise every day and have never had issues like this before now.

  26. I haven’t got it yet, but after readin what everyone says I don’t know!!! I get gout in my feet with some diet pills and it hurts so not sure.

  27. Just wanted to address I am 60 years, fat, lazy, and out of shape. I want this to Work.

    After taking pills for a few weeks I noticed that I started having terrible hot flashes, sweats, and terrible fatigue. I thought the fatigue was just my age so I changed to taking at night. Wow did not help….lousy sleepless nights. I then started a asthma cough that I thought was under control…..these pills seemed to bring back. I am sure some people can take SeroVital-hgh but I am not one of them….to many side effects for me. I feel the company should display side affects.

  29. I haven’t tried this yet but I’m concerned with all the negative comments. It really scares me. I recently had a few thin spots on my scalp but my dr. changed one of my meds but I was hoping this might help????Bald men are sexy but not bald women.

  30. very tired. tired when I wake in the morning and tired later in the day? I am hoping this goes away.

  31. I thought of buying this pills after reading an article in “First Womens Magazine, “but; after reading all the problems some people are having; I have changed my mind in getting them.

    I feel awsome …im 280 lbs on a 5,9 frame .always been in to sports .I play v ball so all that jumping take a toll on my knees plus the heavy lifting on my joints.I wake up brand new every morning and in a super good mood .well rested and clear headed ..noticed it first time I took it no side effects yet ..good stuff

    I am 62 healthy female. Active, but not so much in the past year. I have been taking 4 pills @ 5:00am for 2 weeks. I have been waking up with blurred vision and filmy/crusty stuff on eyes. I do have high blood pressure and think it may be the combination. I have also experienced diahrea, (this is gross, but kind of mucas). I am sending the rest of my pills back. May try the ingredients seperately. Good Luck eveyone.

  34. This product is NOT HGH. The amino acids in this product stimulate the pituitary glad that produces our natural HGH that is in our body. 4 pills is not going to work well for everyone…we are all I suggest people start out with 2 pills. It takes time to feel the effects of the product. If you are sensitive to the aminio acids in the product that stop taking it or reduce the dosage.

  35. I’ve always been very active and in pretty good shape for my age (71) so I figured this product would just be a plus. I’ve been taking Serovital for six months,usually in the morning with a vitamin drink (which at the time I didn’t realize was considered food). I felt like my skin was starting to look a little smoother although I didn’t notice much else change. About a month ago, I started taking it at night with water only before going to bed. Two weeks ago I began having the most awful pains and stiffness in every joint in my body to the degree that I could barely get out of a chair. I stopped taking the Serovital three nights ago and although not completely pain-free, I can at least move, walk and bend without being in agony. There was nothing else that changed in my lifestyle that I could attribute any of this to except the Serovital. I’m hoping that if this was the cause, my pain will continue to abate with each day that I don’t take the capsules.

  36. This stuff is not for me since I read the comments!!

    Don’t like. joints hurt.bloatting. hot flashies increased.headaches and weight gain and only taking 2 pills…

    Reviewed all comments on the new Servitol \hgh product. Given the comments were not really definitive to the plus or negative side of to ingest or not. Seems like another gamble product on the market that makes broad based claims, with marginal test standards in place. A tad surprised that Dr. Oz featured on his program

  39. James Riley // March 22, 2014 at 9:45 am // Reply

    Dr Oz only commented on this product interference to the amino acids and rec amended others.

  40. Thanks for all the people that took the time to warn others about possible side effects. More bad than good. Save the rest of us some $ and pain, Must of us can’t afford.

  41. I’ve been taking the Serovital for two weeks. I have not noticed anything other than I have not felt like an afternoon nap for two weeks. The down side is that I’m having gastric issues – lots of gas, cramping and 6-8 soft bowl movements a day. Have not lost any weight. I’m sending the stuff back. It’s too expensive to be useless and I think it is.

  42. I’m 57 and have been taking Serovital for 3 weeks. I haven’t had a period in over ten years and now have been experiencing breakthrough vaginal bleeding. I can’t say for sure that the usage is connected but it does seem unusual in that I haven’t changed anything else. Anyone else experiencing this?

  43. connie williams // March 26, 2014 at 4:13 pm // Reply

    After reading all the negative comments on Serovital I’m afraid to take it…Are all of these people that are suffering from pain did the pain eventually go away or do you still have it? What does the FDA say about Serovital?

    • Since writing my comment on Marche 17th, it is now two weeks since I discontinued taking Serovital and I’m almost completely pain free. It would be too coincidental for my pain to have come from anything other than these capsules.

  44. After reading the comments I will stick with my Max products. Only side effect I’ve experienced with Max is getting healthy. Fibromyalgia under control with Max too.

  45. Don’t do this people!!! There are so many “hidden side effects” with this product, why put yourself in jeopardy for the sake of loosing a few pounds, or having smoother skin ! It is just not worth it… Our bodies don’t need this hgh… So many people have so many problems or heightened problems from taking this. Save your money and if you want to give your money to something that will help others or animals, go down to a shelter and adopt a pet or volunteer at an organization that really needs YOU… I guarantee you will feel really good and you won’t have any “side effects” for that!!!

  46. I’m a 60 yr old, healthy, active (run 3 miles -5 days a week) female. I’ve been using this product 2 months. I no longer have hot flashes, sleep better, and have less body fat. I have more energy so I work with my weights more too.

  47. Faye Coronado // April 10, 2014 at 6:10 am // Reply

    I bought this a couple of days ago but after reading these comments I will be taking them back it is not worth 84.00 dollars. I am surprised a Air force Base is selling this product.

  48. I’m a healthy 77-year-old woman. Been taking the product for 6 months now, and my only complaint is the PRICE!! I’m a little miffed to discover that others are paying waaay less than I am! I’ll fix that! My experience with Sero-Vital has been positive — had NO NEGATIVE SIDE EFFECTS at all! Can’t say for sure if it’s just the “placebo effect” or not, but I really do have even more energy, higher sex drive, sleep like a baby, and my skin looks good. I’ve also lost 12 lbs without really trying. Plan to continue taking HGH, but may switch to one of the other manufacturers. Not happy with the fact that my supplier is filling/shipping my orders ahead of schedule; I now have a two-month backlog!

  49. I ordered like a month ago and almost at the end of the first month I start feeling like I was ready to vomit, and really not so bad pain in my stomach. So I stop immediately. Should I take more water? or just take 2 instead of 4 pills at night?

  50. I am 41 years old,and I have taken serovital for a month,notice less fatigue,more energy,sleep better, I had a few cramps in my beely,but nothing crazy,at the first day I feel some cramp ay my toe,but did go away.did not notice any diference at my skin ou weight loss,i will may give more time and see if works better,sometimes just need more time.
