FAQ
The questions we get most, answered plainly. For anything not here, email support@pepselect.com.
Peptide basics
A peptide is a short chain of amino acids, the building blocks of proteins. Learn more about peptides in our beginner’s guide.
Research use
No. Everything we sell is research-use-only (RUO) material, intended for laboratory research by qualified professionals. Nothing here is a drug, supplement, or product for human or veterinary use, and nothing on this site is a claim about safety, efficacy, or medical outcomes.
You must be 21 or older to order. By purchasing, you confirm you are acquiring these materials for lawful research use only, consistent with their research-use-only status.
Testing & records
Every batch we have released has a permanent record on our testing page. Search the compound, or enter the batch code printed on your vial, to open the exact certificate of analysis for what you received. Records stay online after a batch sells out.
A batch number is the identifier tied to one specific production batch of a compound. It is how the vial in your hand connects to a single, specific test record rather than a general product claim. Enter it on our testing page and you will land on the certificate of analysis for that exact batch, the same document our team reads. Batch numbers do not change once assigned, so the link between your vial and its record is permanent.
We publish results as the lab returns them, and we do not hide a batch that falls short. A batch that does not meet spec is not sold, but its record stays on the testing page like any other, because a complete record includes the batches that did not pass, not only the ones that did.
Each certificate is the third-party lab's report for that batch: the compound identified, the batch it came from, and the date it was tested. We publish them exactly as the lab returns them, unedited.
Storage & handling
Store lyophilized (freeze-dried) material at -20 °C for long-term storage; 2 to 8 °C is acceptable for shorter periods. Reconstituted solutions are less stable and should be kept at 2 to 8 °C. Avoid repeated freeze-thaw cycles.
Ordering, payment & rewards
Place your order on our website, then check your email for a secure Square payment link. Placing an order does not charge you. Open the link and follow the email instructions to pay the exact order total and finalize your order. We begin preparing your order for shipment once we confirm your payment.
We hold your order for 90 minutes after you place it. Complete payment through the Square link during that time. If we do not receive payment within 90 minutes, we cancel the unpaid order and release its inventory for sale. If your order has expired, contact support@pepselect.com before making a payment.
You earn 3% cash back on every order: 3 points for every $1 you spend, where 100 points is worth $1. Once your balance reaches 500 points ($5), you can turn it into a code from your account and enter that code in the discount field at checkout. Your balance shows in your account.
Email us at support@pepselect.com and we will help you recover it. Include the email address on your account so we can find your record.
