Deca is my country's national steroid. EVERYBODY uses it here. I think deca and testosterone are generally the cornerstones of bodybuilding. Deca works slower than test, there is no dramatic increase in strength or mass like with test or dbol or anadrol, but in contrast to these steroids, you'll keep almost all of the gains you made with deca forever. I think there's no point in using more than 400mg per week, unless you're a 130kg mass monster, otherwise it will be just a waste of gear. I've never had any side effects from it, no gyno, no water retention, no deca dick, testicular shrinkage can be fought by using hcg a few times during the cycle, and doing a proper pct afterwards of course. You'll never get gyno from deca if you are'nt prone to it, and even then this can be fought by using nolvadex or clomid. Testosterone and dbol are much more capable of causing gyno than deca anyway. I suspect that many people in the US have a negative opinion about deca because they've been using fake deca, it's no secret that deca is one of the most faked steroids in the US, so it's very likely that their amps actually contained testosterone or no steroid at all.
