Well like Ivoryrose stated they can be naturally increased through healthy eating etc and None production I know is increased with higher testosterone. My recommendation for that one is if you workout to do some heavy squats very slowly since most of your test is stored in your quads and released into the bloodstream more rapidly when those muscle fibers are broken down. Some of my favorite mones are AMMO, IS, IO, and IH as far as the Consumer line goes. You can actually wear all 4 of these together for an amazing social sexy man vibe that will definitely make you standout from the crowd.
I also reccommend you check out these posts. They will help you out greatly as a new user and I still use them very often.
