To me it seems that the "regretters" are mostly people that started way too young.
I started at 26 and ended up B&C from 29 if I recall correctly, I'm 33 now and to be honest with you, yes, I definitely went on stupid doses and silly cycles in past (which anyways provided me with a deep understanding of how much my body can take) but I don't regret it at all.
And this is coming from a guy that been on non stop for almost 5 years.
My blood results are fine, my liver is fine, my organs are fine, I look good, I'm strong (although strong is subjective) still healthy and recently checked my fertility and is still guess what? Fine.
I may be lucky, I didn't even get bald, actually since starting test I finally grown a full rocking beard (never been able to before) and I even grown long hairs.
Also worth mentioning that I feel very very good year round, sure, I had to give up harsher compounds like nor19 and some orals, I basically use just very few injectables and a couple of orals, basically the stuff that gives me little to no sides, but I don't regret it at all, I'm very pleased with my choice of jumping on AAS.
