Frequently Asked Questions
Everything you need to know about Matter peptides.
-
Peptides are short chains of amino acids (typically 2-50) that act as signaling molecules in the body. They bind to specific receptors on cell surfaces to trigger biological responses like tissue repair, hormone release, immune modulation, and metabolic regulation.
-
Matter peptides are compounded by licensed 503A/503B pharmacies, independently verified for >99.5% purity via HPLC testing, and reviewed by Gabriel AI. Every lot includes a Certificate of Analysis and ships via temperature-controlled cold chain.
-
Some peptides like Semaglutide and Tirzepatide require a prescription. Apotheca offers a built-in Rx intake process with partnered telehealth providers who review your eligibility, usually same-day. Bioregulators and most research peptides ship directly.
-
Lyophilized peptides: store at -20C or below. Reconstituted: refrigerate at 2-8C and use within 30-60 days. Avoid freeze-thaw cycles and strong light. All Matter peptides ship with cold chain packaging when required.
-
A COA verifies the identity, purity, and safety of a peptide batch from an independent lab. It includes HPLC purity analysis, mass spectrometry, endotoxin testing, and sterility results. Every Matter lot has a COA available.
-
Gabriel AI evaluates each peptide across clinical evidence, safety profile, practitioner consensus, manufacturing quality, and source reliability. The resulting score (0-100) helps practitioners quickly assess evidence base and quality. Scores above 90 indicate strong clinical evidence.
