First of all I have to say good job getting through to Oz, and faster than I expected! Great work there. For the rest of it I can't complain. I had a good chuckle about the packaging, thought you were taking the piss but it's a great disguise to be fair. Changes since I started? You could call it an all around "glow". Feels like women check me out more and maybe I get more respect from men? Comes down to confidence, posture and eye contact I reckon but theres been a noticable improvement in my attitude. The actual levels I honestly haven't had a test in ages but they must be great. I basically follow the protocol you recommend and use about 1 tube a month. You might be able to answer that better than me. Anyway cheers and you'll hear from me again in a couple months!
Testosterone is significantly correlated with aggression and competitive behaviour and is directly facilitated by the latter. There are two theories on the role of testosterone in aggression and competition.  The first one is the challenge hypothesis which states that testosterone would increase during puberty thus facilitating reproductive and competitive behaviour which would include aggression.  Thus it is the challenge of competition among males of the species that facilitates aggression and violence.  Studies conducted have found direct correlation between testosterone and dominance especially among the most violent criminals in prison who had the highest testosterone levels.  The same research also found fathers (those outside competitive environments) had the lowest testosterone levels compared to other males.
