Brother, a few things i will mention...1. P6 is a test booster, not testosterone. This means the various ingredients may give a slight test increase (we're talking single digit %) and not always for everyone. 2. Don't bother asking where to get real test on here, afaik it isn't allowed, given the stuff is illegal so that would probably constitute facilitation of selling illegal drugs. 3. I ask this because plenty of the far more knowledgeable guys in here will do the same, what are your numbers? Weight? BF%? macros? Lifting numbers?
Saying you've lifted for yours and have hit your genetic plateau is far different from actually doing it. There are half a dozen guys a day posting in here saying the same thing because their eating isn't dialed in as well as they think, or they aren't going hard enough in the gym or lifting as heavy as they could be to see gains. If you want a source, go ask the resident user in your gym and hope for the best, if you want a basic plan, there are plenty of threads, but you haven't given really any details that indicate you need to bother with steroids yet.
