Why You Get Big On Testosterone…

Of course everybody knows that test is the best! After all, of all the single innovations in bodybuilding over the past 30 years, the "innovation" of taking tons of testosterone is the biggest reason bodybuilders are "75 pounds more muscular" than they were 30 years ago.

Anyway, here's how testosterone works to build so much muscle... First, increased "test levels" dramatically increase IGF-1 level and this alone is enough to put on 20 pounds in some cases. However, the vast majority of the muscle growth inducing capabilities of testosterone are due to its ability to travel into the nucleus of the muscle cell and trigger cellular messengers (these are called RNA). This then triggers what's called "transcription" or the duplication of new DNA (proteins) which eventually wind-up as more muscle on your arms and legs!

But here’s the kicker! Testosterone therapy, according to both Dan Duchaine and Paul Borreson, over time leads to more testosterone receptor development. So this is like a multiplying effect of taking testosterone over a few cycles! So, as you can imagine, more testosterone receptors in the muscle cell means you get "exponential" muscle growth from testosterone therapy over a period of time.

And then of course there's the synergy of increased IGF-1 and testosterone. So as you can plainly see, testosterone is truly the best!
