My two cents..I've been around forever (ARISTIMUQOH) (since the internet started working). This is one of the few BB boards that has been running for many years and to make a long story short, genetics will always play a major role, the digestive system, hormone receptors, etc. are not the same for everyone, so some people can gain a lot of muscle with little gear... just by eating and training smart... I have met the best IFBB BBs that in the off season with 1.5 grams of test and 6 IU of HGH 4-5 days a week become huge, if you need a lot of gear forget to make a carrer in BB for your health. Of course always sticking the best to your body... human grade stuff almost is not available in these days..and there are a lot of garbage (cheaper) in the market..
