literally all these years there was ONE fucking booster that i saw significant changes with but of course they went out of business when the pro hormone ban came down... i managed to find a bottle last week online that i did get but good luck with that because they are just not around.... at least with high quality... im sure there are a few new ones out there that are decent but most of us would not know or care because they are not anything generally used by anyone who has a real strong concept of anabolics, functoning and use...
