Go live in the county jail for a year then ask the same question, testosterone is the key to a long life and earthy life, combined with nutrition and exercise the male specimen can maintain vital health, energy, muscle building, sexual health, and many other positive factors....... When your 45, and decided when you were 27 juice is pointless, ahh you tell yourself it's not necessary, it's no use because your not a pro athlete so when you know the power of the medicine and your 48 and you run across a pro HRT 47 year old man who is 260 lbs jacked and you then think to yourself, maybe I didn't fully understand the uses of testosterone and other AAS substances, in a mans life one day he can become fully schooled on the uses of AAS from HRT to AAS abuse, and then the understanding of why a man takes the slecial sauce will hit ya!
