Incretin-axis and metabolic research.
Reference standards.
Tesamorelin · MOTS-c — converging metabolic axes: visceral-adipose GHRH stabilization and mitochondrial AMPK signaling.
METABOLIC research bundle.
The compounds below are the convergent-mechanism set used in the published preclinical literature for metabolic research. Bundled with bulk savings vs ordering individually. Same per-lot COAs as single vials.
Every batch ships with HPLC purity + LC-MS identity on a per-lot COA, traceable to the lot in the vial QR code.
Most vendors lock the COA behind a "request" form. We publish ours at /coa/.
Receptor class and primary preclinical references on every product page. No marketing language, no human-use claims.
A research-peptide supplier that shows its work.
X Factor exists because the RUO market has spent a decade selling unmarked vials with no provenance, no mechanism, no citations. We list the receptor class on every product page, give every lot its own page in a browsable library, with the supplier certificate published on it when we receive it, attest to RUO at checkout, and audit-log every admin action. Maryland HQ. US-sourced, and we require the supplier's per-lot COA for every lot.
