Appetite Suppression

Phentermine

Phentermine is a sympathomimetic appetite suppressant that has been used safely for decades. It's a short-term tool — most useful for men who need momentum at the start of a program or who've plateaued and need a 2–3 month nudge.

How it works

The mechanism

Phentermine raises norepinephrine in the central nervous system, reducing appetite and slightly increasing energy expenditure. Effective when paired with structured nutrition and training.
