look i dont want to be a dick but 1) cyp is a long acting ester freakishly similar to enanthate so it comes down to personally prefrence. 2) an ester is an ester regardless if its ASS or PH it still gonna have the same half-life. 3) who the hell injects a cyp ester eod? i can understand 2x/wk that what i do but this is not prop. my advice more research is needed
