Frequently Asked Questions

Yes, an account is required. This lets us tie order history, tracking, and COA references to your profile so you can access them at any time from My Account.

We accept all major credit and debit cards — Visa, Mastercard, American Express, and Discover — processed securely through Stripe. Payment card details are never stored on our servers.

Orders cannot be cancelled once placed. All sales are final. Please review your order carefully before completing checkout. If your order arrives damaged or incorrect, see our Shipping & Returns policy.

We occasionally run promotions for new customers. Promo codes can be entered on the cart page before checkout. Watch our social channels for announcements.

Our compounds are sold strictly for in-vitro laboratory and scientific research purposes. They are not approved by the FDA for human or veterinary use. By purchasing, you confirm you are a qualified researcher complying with all applicable laws.

A COA is a third-party laboratory report confirming the identity and purity of each batch, tested via HPLC and mass spectrometry. Every batch we sell has its own COA linked directly from the product page — you can verify what you're ordering before you buy.

Independent third-party laboratories perform HPLC (High-Performance Liquid Chromatography) and mass spectrometry on each batch. HPLC quantifies purity as a percentage, and mass spectrometry confirms the molecular identity of the compound.

Yes. All compounds are supplied as lyophilized (freeze-dried) powder, sealed under inert gas. This format maximizes shelf stability and makes them safe to ship at ambient temperature.

Add bacteriostatic water slowly along the vial wall to avoid agitating the lyophilized powder; do not shake — swirl gently until fully dissolved. Exact dilution ratios depend on your specific research protocol. These are general parameters for in-vitro laboratory preparation only and are not instructions for human use or administration.

BAC is sterile water with 0.9% benzyl alcohol, which prevents bacterial contamination in your prepared solution. It is the correct diluent for compound laboratory preparation. We carry it directly — you can add it to your order on our products page.

Store lyophilized compounds in a cool, dry place away from direct light. Refrigeration at 2–8°C is recommended for extended storage. Keep vials sealed until use.

Once prepared with bacteriostatic water and stored refrigerated at 2–8°C, most compounds remain stable for approximately 4–6 weeks under in-vitro laboratory conditions. Consult the individual COA and peer-reviewed literature for compound-specific stability data. These guidelines are for laboratory research use only.

Orders are typically processed within 1–2 business days. Transit time depends on the shipping method selected at checkout. You'll receive a confirmation email with tracking once your order ships.

Lyophilized compounds are stable at ambient temperatures for several days and do not require cold-chain shipping. Sealing under inert gas preserves stability during transit. Once you receive your order, refrigerate promptly.

Once your order ships, you'll receive an email with your tracking number. You can also visit certifiedpeps.com/track-order and enter your order number or email — no login required.

We currently ship within the United States only. International shipping is not available at this time.
