Purity Is Our Priority.

Most orders ship the same or next business day. When your order ships, your tracking number is emailed from order@primescience.st. If you haven’t received it within 1 business day of your order confirmation, check your spam folder, then contact us with your order number.

We accept Visa, Mastercard, American Express, Google Pay, Apple Pay, Afterpay, and Interac e-Transfer.

Every batch of our peptides and other compounds is tested by Testides Analytical, an independent third-party laboratory. The only exceptions are pharmaceutical products and reconstitution supplies (bacteriostatic water and acetic acid). The Certificates of Analysis (COAs) for each batch are on the product page, so you can match them to the batch you receive. Our only official website is primescience.st.
