Very effective, but don't waste the money unless you can afford at least 5 kits(500iu's). 4iu's/day for me. Permanent gains bro. The only problem I ever get is hand/wrist pain with like carpal tunnal syndrome symptoms.
Well I run alot of juice with my GH so its hard to say how much weight I gained after my 1st kit. But to answer the question, around 10-12 lbs after the 1st kit then around another 12-15 lbs after the 5 kits for a total of 25 lbs. Was also cock strong with a healthy energetic feeling. I like Test Cyp, Deca, Winstrol with my Jintropin.
