A SARM is a selective androgen receptor modulator. It will act like a SERM on the hypothalamus to stop the inhibiting effects of the feedback loop. It would have to be stacked with a SERM or an AI, and even then T production would be limited to what is physiologically possible. It would elevate T levels, but nothing like injecting T.
It's most likely BB application will be to stack it with injectable T (+ AI or SERM) in order to keep natural production going while on cycle.
Hate to say DK, but you'd get better responses on the S&H board.
