Frequently Asked Questions

Explore clear, compliance-focused answers about peptide purity, storage requirements, lab testing, and product handling.

1. Are your peptides for human use?

All products sold by Limitless Peptides are classified as Research Use Only (RUO) chemical compounds. They are not for human consumption, veterinary applications, or diagnostic purposes.

2. How do I know the purity of your products?

We prioritize transparency. Every peptide batch is verified by an independent, third-party laboratory using HPLC-MS. The Certificate of Analysis (CoA) is available upon request and confirms the purity profile of the compound you receive.

3. Is a prescription required to purchase?

No, a prescription is not required as our products are sold strictly as Research Use Only compounds, not as pharmaceutical drugs. By purchasing, you are confirming your status as a qualified researcher or institution.

4. How should I store my peptides?

For long-term stability, peptides should be stored as a lyophilized (freeze-dried) powder in a deep freezer at below -15°C (-4°F). For short-term storage, a standard refrigerator (+4°C) is sufficient. Protect the product from moisture and light.

5. How long do peptides last in storage?

When stored properly as a lyophilized powder at -20°C, peptides can remain potent for six months to several years. Once reconstituted (dissolved in solution), stability may decrease and refrigeration is recommended.

6. How do I reconstitute a peptide?

All peptides need to be reconstituted with bacteriostatic water (BW), 0.9% NaCl solution, or 0.1% acetic acid solution.
