i can only speak from my experience
..went thru 10kits of DIRECT's GREYTOPS and i was giddy with the results
^^^my dose was 3.33iu/day
^^^really thought the G/Ts were the best going until i tried DIRECT's RACETROPIN and WOW ..it was even better/cleaner than the GREYTOPS
..this stuff had no bloat for me and felt like twice the dose (..again i was runnin' 3.33iu/day)
..had numbness in my hands for the first couple of wks, but then went away
..had to switch from taking my full dose in the AM to before bed cuz these were just too much and tended put me down
..when i switched to inj before bed, i slept soo soundly ..i really felt amazing
..i looked forward to inj in a way that hadn't in years just cuz the improvements seemed to come on daily
..before that the best GH i'd used came from "Homer"
^^^that was also very good GH and i used him almost exclusively for years
again, this post is not loaded ..i'm very much a "user" so this is just my own honest feedback and comes from what i use/have used
..to me, my experience is the only thing i can comment from
..do your own due diligence and seek out the test results/feedback
