How the guarantee works →Before you order
All questions →Where are the peptides made?
In the United States. Every compound is synthesized, filled and tested domestically, and published lot Certificates of Analysis let the claim be checked before purchase; a very recent lot may appear in the library a few days after it enters the catalog.
How is a lot tested, and where is the COA?
Before release, a lot goes to an independent third-party laboratory for HPLC purity analysis and mass-spectrometry identity confirmation. Where a lot's certificate is published, it appears on the product page and in the COA library, and the QR code on the vial label opens it.
What does shipping cost, and how fast is it?
UPS Ground $20 (free on 3+ vials or $100+), 2-Day $15 (free at $250+), Next Day Air $60 (free at $600+), on products after discounts, water out. US only. Paid by 2:00 PM ET on a business day, it ships that day; later, the next. 2-Day takes 2 business days.
How can I pay?
Credit and debit cards, including Link, Stripe's saved-card checkout. Card details are entered on Stripe's secure form on the checkout page and never touch our servers; the order enters processing as soon as the payment goes through.
Do I need an account to order?
No. Checkout works as a guest. After you submit, we email a one-click magic link that signs you in to view, edit or pay for the order, with no password required. You can set a password later if you prefer.
