NoFap for Jawline & Testosterone
The testosterone spike people cite is a small, transient blip around day seven that returns to baseline. No hormone level in that range reshapes an adult face.

Verdict — cope
The mechanism does not hold. Your time is better spent elsewhere.
Evidence grade C
Mechanistic plausibility, small studies, or observational data. Suggestive, not established.
Mechanism
One small study found a transient ~145% rise in serum testosterone at day seven of abstinence, returning to baseline afterwards. Adult craniofacial morphology is not androgen-responsive in any case.

The full read
The single study this is built on is real and says less than the claim needs: a short-lived spike, within physiological range, not sustained. Even a genuinely elevated level would not move bone — facial dimorphism is set during pubertal growth, which is the same reason `trt-for-looks` fails at this. The reported benefits people actually experience — more energy, better focus, more time — are plausible outcomes of breaking a compulsive habit and reallocating hours, and those are worth having on their own terms. Claim that, not the jaw.
