Biology & mechanism

A tetra-substituted GHRH(1-29) analog. The four substitutions resist enzymatic degradation. The DAC (Drug Affinity Complex) variant adds a reactive linker that forms a covalent bond with circulating albumin, extending half-life from minutes to roughly one to two weeks — which converts pulsatile GH release into a sustained elevation, a pharmacologically significant departure from normal physiology.

What the research actually shows

Early-phase human pharmacokinetic work exists from the original developer, showing sustained GH and IGF-1 elevation. Development was not carried through to approval. There are no adequate controlled trials supporting efficacy for any clinical outcome.

Regulatory status

Not FDA-approved. No USP monograph. Placed on the FDA's 503A Category 2 list, then removed in April 2026 after the nomination was withdrawn — but not moved to Category 1. It occupies a regulatory grey zone: neither expressly permitted for compounding nor expressly prohibited. Prohibited in sport (WADA S2).

Safety signals

Sustained rather than pulsatile GH elevation is the central unknown; chronic GH-axis stimulation is associated with insulin resistance, oedema, arthralgia, and theoretical malignancy-promotion concerns. Long-term human safety is uncharacterised.
