It would depend on the source and Quality
Back in the day 4-6 iu's of sero would cripple someone with carpal tunnel-nerve numbess, and it was rare to here people taking over 10 iu's of Jins a day.
Raw deal ended the "legit Chinese GH" coming from the factory, and the insurance companies ended the huge supply of seros on the market when they stopped approving a kit a week for AIDs pateints.
Of course EVERYONE claims their unlabeled multicolored vial with messy cakes in them came out the back door from gen-sci. LOL
It also been comical to read over the years "Dillet (example only) took 36 ius of SEROS a day" and all the pros use 20-30 iu's of GH a day plus 100 iu's of slin and 5-10 grams AAS a week-funny those same pros are competing today and should be dead if they abused their bodies that much.
If you can tolerate that much GH from today's black market like some post about it is NOT very potent at all.
