There's more to muscle growth than T levels bro.
Very true Obi Wan.
Here's something I posted in the women's section when one of the girlies wanted to increase her test naturally.
What I would like to address is that people think that testosterone is the only thing, best thing etc. that will enhance muscle growth.
It isn't.
There was an interesting article in last month's Muscular Development, April 08 (the one with Evan Centopani on the cover) that had an interesting bit of older research in it.
The whole article was about time under tension being necessary for muscle hypertrophy.
In the 70s some scientists used lab rats and removed the following endocrine glands, the thyroid, testicles, pituitary (growth hormone is secreted from here) or they didn't feed them, and then basically put the rat's rear legs under tension/simulated weight training.
They had postulated that muscle would not grow with out these hormones.
They found out they were wrong.
Now it is postulated that there are some other signalling pathways such as mTOR or MGF (mechano growth factor).
Oestrogen is also anabolic in women, and I would have to see if I can find it again, but there is some sort of connection between growth hormone and oestrogen.
Also the lads have found that when they use oestrogen inhibitors when they do a cycle, their gains are inhibited.
My point, while testosterone is anabolic, there are other things going on as well.
The endocrine system is really complicated, quite amazing really, and the exact mechanism of muscle hypertrophy is not known.
It may even be discovered that it is different in men than women.
It may just be twigging dietary and training factors, and some supps that will make the difference.
I would suggest you focus more on triggering natural growth hormone release, rather than trying to increase your testosterone levels.
