You ask,
we answer.
Are these peptides quality tested?
Are these peptides quality tested?
Absolutely. Our analytical testing is conducted by Janoshik Analytical, BioRegen, or Freedom Diagnostics, independent third-party laboratories that verify the identity, purity, and composition of our research products. All products are guaranteed to test at 98% purity or higher. Each CoA includes purity analysis, peptide sequence confirmation, date of analysis, and an endotoxin report.
What are typical delivery times?
What are typical delivery times?
Delivery for our free shipping option typically takes 3-5 business days. We ship from right here in the USA to all US addresses. We also provide an option for next day shipping for an extra charge. Please allow 24 hours for processing. Every package comes with professional packaging and tracking updates via email.
How should these compounds be stored?
How should these compounds be stored?
Our peptides are shipping in lyophilized form, which is stable at room temperature during transit. Once received, store unopened vials in a cool, dry place.
Are products stable during shipping?
Are products stable during shipping?
Our peptides are shipped in lyophilized (freeze-dried) form, which ensures stability during transit. This powder form is highly stable at room temperature and resistant to temperature fluctuations that occur during shipping. Research has shown no significant degradation or loss of purity when lyophilized peptides are exposed to room temperature during typical shipping timeframes. Each batch is verified for purity upon production, and our stability testing confirms maintenance of product integrity during standard shipping conditions.

What payment methods do you accept?
What payment methods do you accept?
We accept credit/debit cards. After you place an order, we'll email you a secure payment link. Please complete payment within 48 hours. Unpaid orders are automatically canceled after that window. If you don't see the email, check spam/promotion or contact support and we'll resend the link.
What is the shelf life/expiration of unopened vials?
What is the shelf life/expiration of unopened vials?
Each lot lists a best-by/expiration on the vial label and COA. As general guidance, lyophilized peptides stored as directed are typically stable 12-24 months (often longer at -20 °C). Short shipping periods at ambient temperature are normal. Actual stability depends on sequence and storage conditions.
