How to Vet a Peptide Vendor
Before you buy from any online seller, check these signals of quality:
- Third-party COA – a recent certificate from an independent lab, not the vendor's own lab.
- Purity claim – legitimate research peptides usually list 98% or higher purity by HPLC.
- Payment security – reputable vendors use mainstream credit card processors or verified payment gateways.
- Return policy – a clear refund or replacement policy is a sign the vendor stands behind its products.
- Transparent contact – a physical address and phone number, not just a contact form.
Even with these checks, no online vendor can guarantee safety for human use. The FDA does not regulate research peptides, so the burden of verification falls on the buyer.
Safety, Legality, and FDA Status
The FDA has not approved any peptide for over-the-counter sale for muscle growth. Selling peptides for human consumption without approval is illegal in the United States, though many vendors operate in a legal gray area by labeling products "for research use only."
Buying from unregulated sources carries risks of contamination, incorrect dosing, and unknown side effects. Injectable peptides also carry risks of infection and allergic reaction if not prepared or stored properly.
Always consult a licensed healthcare professional before using any peptide, especially if you take prescription medication or have a medical condition.
If you are considering peptides for muscle growth, ask your doctor about FDA-approved alternatives and whether any clinical trials are recruiting. Do not rely on online reviews or vendor claims as medical advice.
