Frequently Asked Questions

PSL Labs sells synthetic peptides and related materials for laboratory research. PSL Labs is operated by PSL Group LLC in Phoenix, Arizona. We publish third party lab reports and batch information that you can review yourself.

No. Everything we sell is for laboratory research and analytical work only. Not for human or animal consumption, and not intended to diagnose, treat, cure, or prevent any disease.

No. We do not advise on dosing, administration, injection, therapeutic use, or human reconstitution. Support covers orders, shipping, and batch documentation. Materials belong in a lab with qualified researchers.

PSL Labs does not create the lab reports shown on the site. Our published reports come from Janoshik Analytical, an independent laboratory. We do not rely only on manufacturer certificates.

Yes. Each Certificate of Analysis covers one production batch and the sample the lab tested. We do not reuse old reports for newer batches. New batches get new testing and a published report before release.

Each published report includes a task number and a link to the lab. Confirm the original file at verify.janoshik.com so you are not relying on a copy that could have been edited.

For our published peptide batches, the Janoshik report shows three main results: the material identified by the lab, the reported purity, and the amount measured in the tested sample. The original report shows the full test details and results. The report only covers the tests shown on the original laboratory file.

Right now we accept Bitcoin only, through BTCPay Server. Card payments are temporarily unavailable. Bitcoin gets a 5% discount on the product subtotal at checkout.

You need a Bitcoin wallet with enough BTC to cover your order, for example a mobile wallet or an exchange account that can send Bitcoin. At checkout, enter your contact and shipping details and choose Bitcoin. You'll be redirected to our secure BTCPay checkout, which shows the exact amount to send and a payment address with a QR code. Send that exact amount from your wallet before the invoice time limit runs out; your wallet sets the network fee. If the invoice expires before payment, start checkout again for a new invoice. Your order is marked paid once the payment is confirmed.

We ship to physical addresses in all 50 U.S. states from Phoenix, Arizona. Standard shipping is $9.99. A product subtotal of $100 or more before discounts gets free standard shipping. When offered at checkout, USPS Priority Mail costs $24.99 when the product subtotal after discounts is $100 or less, or $22.99 when it is over $100. This threshold excludes tax and shipping charges. Availability depends on your shipping address and parcel. The Priority price replaces Standard shipping; it is not added to the Standard charge. Orders usually process within 24 hours after payment clears. Carrier acceptance or collection may occur on the next operating day. USPS Ground Advantage transit is usually 2 to 5 business days after carrier acceptance for most contiguous U.S. destinations. Alaska and Hawaii can take longer. Carrier estimates are not guaranteed.

When tracking is saved to your order, we send a shipping email with the tracking number. Label creation alone does not mean carrier acceptance. You can also check status anytime on Track Order (/track) with your email and order number.

Take clear photos of the outer box, shipping label, packing materials, and any damaged or wrong items. Email support@psllabs.org with your order number and photos. We review claims under Returns & Refunds (/returns).
