The second theory is similar and is known as "evolutionary neuroandrogenic (ENA) theory of male aggression".   Testosterone and other androgens have evolved to masculinize a brain in order to be competitive even to the point of risking harm to the person and others. By doing so, individuals with masculinized brains as a result of pre-natal and adult life testosterone and androgens enhance their resource acquiring abilities in order to survive, attract and copulate with mates as much as possible.  The masculinization of the brain is not just mediated by testosterone levels at the adult stage, but also testosterone exposure in the womb as a fetus. Higher pre-natal testosterone indicated by a low digit ratio as well as adult testosterone levels increased risk of fouls or aggression among male players in a soccer game.  Studies have also found higher pre-natal testosterone or lower digit ratio to be correlated with higher aggression in males.     
My brother has been compounding my hormones since 2000. I just saw a doctor who ordered blood tests to check my hormone levels, primarily because my hair won't stop falling out. The doctor's office faxed the results to my brother and she had prescribed testosterone cream on the labia. I didn't like that answer and now the doctor is in Australia until mid January. The way my brother explained it is that the testosterone will increase the libido, it will build up muscle tissue and do several other positive things. It is not dangerous to apply to the labia. I am going to call the office and ask that another physician explain the results to me. Compounding HRT is the way to go. The pharmacist can closely duplicate the hormones naturally produced in your body when menopause causes them to produce less.
Bro, these things are for people who want to psyche themselves to bulk up. I read that on the animal stack 2 orientation aswell. By only looking at the exterior only, you wont see the beautiful part. Its what we BELIEVE is working for us, based on ingredients. I was lead to your post here from the same testogen that previewed beneath all the wonderful things the other site had to say about pronabolin. So Should i buy both that ‘and’ the testogen? I just wanted a vacuum tight waist area to go with a semi Simeon Panda look for when im an experienced body builder. Whats the deal with all this sex talk and testosterone talk? Not sure, but i think pronabolin is just supposed to help bring in your waist line. So you can tap into your true potential. Results dont come over night unless you’re using some kind of steriods man. You know that. A smaller waist, can be earned through pronabolin. You just have to keep taking it and focus on that. Its what i would hope for. With my Simeon Panda muscles. The girls like the love handles. But unfortunately i havent commit to exercising and body sculpting yet. And it takes years to get results if we arent kids anymore or nolonger 25. You cant rush something like exercise, unless you’re using steriods. Guys over 40 wont get instant results even. And you what that fact relates to im sure. They just cant thats why. Unless they stay in the gym. Its a commitment not master Roshi from dbz performing his transformation trick. So you got me. I want both products now lol …I can bet that pronabolin makes sense because it maintains muscle mass and skin tightness why people claim itd keep you younger. Great sale anyway you put it.
