Inhibit the production of Myostatin in your body with Follistatin.

From Wiki article:
>Lee & McPherron demonstrated that inhibition of GDF-8, either by genetic elimination (knockout mice) or by increasing the amount of follistatin, resulted in greatly increased muscle mass.

of course, this has not been tested on humans

Lack of or inhibition of myostatin is why apes are strong enough to tear your arms off.

<pic related, never lifted weights but ripped as hell

good luck getting someone to synthesize it for you
