gonna disagree with 4th on this one. fina pellets offer 100% pure tren ace. if you do the conversion correctly and take your time. and its guaranteed to be 100% pure. any UG making tren has to go on their sources word that what their getting is legit, and even in that case access to pur epowders isnt common, at least in my experience with powders. since there is no available tren anywhere that can be guaranteed to be real tren, fina pellets are the ONLY way of knowing for sur eyouve got 100% pure and real trenbolone acetate... again, youve got to take your time on the extraction and do it right. get the hormone isolated and dry it out and weigh it on its own.. extraction % is never 100% (yuou will always lose a little bit of the tren ace during extraction process), but the end result is always pure
