Frequently Asked Questions

Find answers to common questions about our products, shipping, and policies.

What are research peptides?

Research peptides are synthetic amino acid chains used exclusively in laboratory research settings. They are not intended for human consumption, veterinary use, or any clinical application.

How do I store my peptides?

Store lyophilized peptides at −20°C for long-term storage. Once reconstituted, store at 2–8°C and use within 14 days. Avoid repeated freeze-thaw cycles.

What is a Certificate of Analysis (COA)?

A COA is a document from an independent laboratory confirming the identity and purity of a compound. Our COAs include HPLC purity data, mass spectrometry confirmation, and endotoxin testing results.

Do you ship internationally?

Currently we ship within the United States only. International shipping options are being evaluated for qualified research institutions.

What payment methods do you accept?

We accept major credit cards, ACH bank transfers, and cryptocurrency. All transactions are encrypted and PCI-compliant.

What is your return policy?

Due to the nature of research compounds, we cannot accept returns on opened products. Unopened products may be returned within 30 days for a full refund.

How is purity verified?

All products undergo HPLC (High-Performance Liquid Chromatography) and Mass Spectrometry testing by independent third-party laboratories. Results are documented in each product's COA.

Do I need an account to order?

Yes, you must create an account and verify your research credentials before placing an order. This ensures compliance with our research-use-only policy.

What are stacks/bundles?

Stacks are pre-configured combinations of complementary research peptides offered at a discounted price. They are designed for researchers studying related pathways.

How quickly do you ship?

Orders placed before 2PM EST Monday–Friday ship same day. Standard shipping is 2–5 business days. Expedited options are available at checkout.
