Genetices = hyper responders to drugs. Guys that make it are hyper responders to drugs. Mixed with years of sacrafice , training, determination. Yes really. As for powerful drugs lOl. Most are on ug shit. Varying qualities per batch.... peptides which quality is highly questionable. And the the most powerful, slin most dont take enough as needed. Top guys just respond better, and can take longer periods of abuse. There are thousands on mgf, igf, waking up with slin, injecting humalog every meal Etc. That look like shit. Anyone cant just juice and look like a pro...
