What you get with a Pepta Labs order

Documentation
The reported HPLC purity is shown on every product page. The independent lab’s HPLC purity and MS identity report is sent by email on request, before you order if you want to see it first. Because testing is commissioned by the purchasing group, the client field may name the group or source rather than Pepta Labs, and supplier-identifying fields are redacted.
Labels
Vial labels identify the compound, quantity and research-use designation. They do not carry lot or batch numbers.
Not claimed
Sterility, endotoxin or LAL, potency, pharmaceutical-grade, cGMP, contaminant-panel or vial fill-quantity testing. The listed quantity is a supplier-stated nominal quantity.
Shipping
Free US shipping on every order, no minimum. Most orders ship the next business day. Sealed lyophilized powder ships at ambient temperature. US addresses only.
Ordering
Orders are placed from a registered account with a confirmed email, and every order carries an electronic research-use certification. Buyers must be 21 or older.
Returns
Unopened products in original sealed condition may be returned within 30 days of delivery with return authorization from support@peptalabs.com. Return shipping is the buyer’s responsibility unless we shipped a damaged or incorrect item.
