was having a chat with my contact in the world of GAA training at top level about this last night. he was telling me that Animal Stack has been the go to supplement at certain clubs and county level for over ten years.
this seems to be a version of it https://www.bodybuilding.com/store/univ/stak2.html
what you do is take it like a loon outside of the season, and then you Tyson Gay yourself for the rest of the year, as the gear leaves your system but the mass improvement remains. So you get a slight looking lad transforming in the space of a year into a very big lad indeed. We've all seen that.
long term it causes kidney liver and heart problems. We've all seen that as well. that and variations of it are everywhere, he says. If you want to be 100% safe stick to Holland & Barrett and shops like that, otherwise dont. The bodybuilding shops are rife with stuff which isnt even in English, you really haven't a bog what can be in them. He is adamant (and to be fair he said it a year ago) that the GAA at all levels is a timebomb.
the running scene angle is off topic, but he was telling me in great detail about the amounts in the club scene, its bonkers.
