in terms of the HGH talk in this thread...if you know anything about its effects when used in suprahuman dosages for extended periods of time...it doesn't really do much at all...

There is something called Insulin-Like Growth Factor (IGF-1) with is a peptide injected in order to increase protein synthesis and repair and actually cause hyperplasia (the growth of new muscle tissure instead of hypertrophy which is the growth of existing tissue)

IGF-1 has better effects, less side effects, and is undetectable because the half-life of the most popular form of the chemical is only like 4 hours.

Let's all be honest here:

Most athletes today are on some sort of performance enhancing drug. There are a ton of drugs out there you wouldn't/couldn't imagine that are in use as we speak by professional bodybuilders around the world and that technology quickly trickles to pro-sports/the average weight lifter wanting to lift more or look better doing it.
There are things such as myostatin inhibitors that will literally in the next 6 months to a year decrease the body's ability to slow muscular growth. There was a baby born in germany of all places that was born w/ out the myostatin gene and his legs/calves are already 200% normal size and he hasn't reached the ripe old age of 2! He builds muscle by simply walking and crawling


I'm saying all this because i've done my fair share of research for my degree and the drug issue is much more prominent than even the little "inside" reports on HBO let on.
