The Evidence

We cite the compound, not the claim.

Every figure on this site points to peer-reviewed research on the active compound — real journals, real trials. Not marketing.

Jastreboff et al. · NEJM 2023

"Retatrutide produced a 24.2% mean reduction in body weight at 48 weeks in the Phase II trial."

The triple-receptor compound in Peak Burn — the most significant weight-loss data published to date.

Trammell et al. · Nature Communications 2016

"Human blood NAD+ rose as much as 2.7-fold, with dose-dependent increases across the trial."

The first human pharmacokinetic data behind Peak Rewind — measurable NAD+ elevation, in people.
