Source Integrity
Why source matters
The peptide market has a quality problem. Most of what is sold online is not what the label says it is. The chemistry is unregulated, the supply chain is opaque, and the consequences land on the person doing the injecting.
70-90%
Of peptides sold online originate from bulk Chinese synthesis facilities with zero independent oversight.
1% - 100%
Purity range found in independent lab testing of research-grade peptides. The vial may contain almost none of the listed compound.
March 2026
FDA issued formal warning letters to research-peptide companies, ending the gray-market "research use only" workaround. Our model — a licensed 503A compounding pharmacy with a prescribing physician — has always been the regulated path.
// the problem
The overseas supply chain is a black box
- Heavy metal contaminationLead, cadmium, and mercury have been documented in overseas peptide imports. These are injected directly into the bloodstream.
- Counterfeit compoundsIllicit semaglutide seized by European regulators tested as an entirely different substance. The vial said one thing, the contents said another.
- Fabricated certificatesA Certificate of Analysis from an unaccredited source is a PDF, not a guarantee. Many online sellers recycle the same fake document across batches.
- Regulatory collapseThe FDA’s March 2026 enforcement action gave non-compliant research peptide sellers 15 days to cease shipments. Buyers lose their supplier overnight, with no recourse.
// the greenstone standard

How to Reconstitute Peptides: The Step-by-Step Reference
Reconstitution is the first critical step in any peptide protocol. This reference covers bacteriostatic water versus sterile water, concentration math for common vial sizes, proper mixing technique, post-reconstitution storage, and the errors that compromise peptide integrity.
