Frequently Asked Questions

We offer a curated selection of research-grade peptides across three main categories: Peptides (including BPC-157, TB-500, GHK-Cu, MOTS-c, and Tesamorelin), GLP Agonists (RETA, SEMA, and TIRZ), and Peptide Blends (pre-formulated multi-compound blends for laboratory protocols). All products are intended exclusively for laboratory research and development.

Yes. Every batch undergoes third-party HPLC (High-Performance Liquid Chromatography) testing to verify identity and purity. Our peptides consistently achieve 99%+ purity.

Lyophilized peptides are in freeze-dried powder form, which provides maximum stability and shelf life. Reconstituted peptides have been dissolved in a solvent (typically bacteriostatic water) and are ready for use in research applications. We ship all peptides in lyophilized form for optimal stability during transit.

To reconstitute a lyophilized peptide: (1) Allow the vial to reach room temperature. (2) Using a sterile syringe, slowly inject bacteriostatic water along the inside wall of the vial — do not inject directly onto the powder. (3) Gently swirl the vial until the powder is fully dissolved; avoid shaking vigorously. (4) Store the reconstituted peptide at 2–8°C and use within 30 days. Specific reconstitution volumes vary by product — refer to the product documentation for recommended concentrations.

Orders are processed and shipped within 1–2 business days via FedEx 2-Day Express, so most orders arrive within 2 business days of shipment. All orders include tracking information sent via email once your order ships. Temperature-sensitive items include cold packs when required.

Yes! We offer free FedEx 2-Day shipping on all orders of $200 or more. Orders under $200 ship for a flat rate of $12.00. We also occasionally offer promotional codes that include free shipping at any order total. See our shipping policy for full details.

Currently, we ship within the United States only. All products are tested and shipped from our USA-based facility. We are evaluating international shipping options and will update our shipping policy when available.

We accept a wide range of payment methods for your convenience: credit and debit cards, cryptocurrency, Zelle, bank draft (ACH), and Wallet Up. All transactions are processed through secure, encrypted payment gateways.

For optimal stability: Lyophilized (powder) peptides should be stored at -20°C for long-term storage, or 2–8°C for short-term storage (up to 3 months). Reconstituted peptides should be stored at 2–8°C and used within 30 days. Always keep vials away from direct light and excessive heat, and avoid repeated freeze-thaw cycles to maintain compound integrity.
