Frequently Asked Questions

Everything researchers ask before ordering peptides.

All orders ship in plain, discreet packaging with no external branding. Tracking is provided by email within 24 hours. Lyophilized peptides are temperature-stable in transit and do not require refrigerated shipping.

Sealed and stored at −20°C, the lyophilized powder maintains potency for 24+ months. Once reconstituted with bacteriostatic water, store at 2–8°C and use within 30 days.

Yes. Every order ships with a batch-specific COA from an independent ISO/IEC 17025 accredited lab. You can preview the current batch COA above before ordering.

We accept all major credit cards and select alternative methods. Charges appear under a discreet, non-descriptive merchant name on your statement.

We ship within the United States only at this time. International researchers should review their local regulations regarding research-use peptides before placing inquiries.

Allow the vial to equilibrate to room temperature before opening. Inject bacteriostatic water down the side of the vial — do not spray directly onto the lyophilized cake. Swirl gently. Do not shake. Use the on-page reconstitution calculator for exact volumes.

Because these are research-use peptides, all sales are final. If your order arrives damaged or incorrect, contact us within 7 days and we will reship or refund.

No. All products are sold strictly For Research Use Only (RUO). They are not drugs, supplements, cosmetics, or food and are not intended for human or veterinary consumption.
