Incretin-axis and metabolic research.
Reference standards.
Semaglutide · Tesamorelin · MOTS-c — three converging metabolic axes: GLP-1R agonism, visceral-adipose GHRH stabilization, mitochondrial AMPK.
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, publish per-lot COAs in a browsable library, attest to RUO at checkout, and audit-log every admin action. Maryland HQ. US-sourced, with a supplier per-lot COA on every lot.
