The key with primo is getting REAL primo. I don't beleive a lot of what I read online. There are so many agendas but I think that the reviews would be a lot less mixed on primo, if it weren't for people getting fake or under dosed gear. Primo is very expensive and there is good profit in faking it. When it's real, it's a great compound for cutting and has low side effects. I would run it along side of some test e and do my injections at least 2x wk. Personally, I prefer to split my gear into smaller doses and in the OS, will do EOD injects. By contest time, I move to ED injects. So if I were using primo at 700mg, I would do 100mg ED. I just find that using smaller shots, more often, gives me less scar tissue and allows the site to heal faster. speaking of primo, I have not tried the newer Geneza 200mg version, but the primo 100 is good. The 200mg is on my list of things to do ;)
