BioLongevity Labs coupon code PCT15 gives a 15% discount on the cart subtotal at checkout, and a small first order is a practical way to confirm how the discount behaves before you place a larger one.

The discount is taken off the cart subtotal at checkout. It is not paid back later as store credit, so the reduction you see before payment is the one you keep. A trial order lets you check that the discount line appears correctly on your own account, device and basket before you commit a larger purchase. The coupon field is usually case-insensitive but rejects stray characters, so a short test also shows whether the code is typed cleanly.

BioLongevity Labs describes a catalogue of more than 150 research-grade peptides and bioregulators, sold in lyophilised vials, capsules and topical preparations. Named products in the knowledge include BPC-157, TB-500, Epithalon, NAD+, Cartalax and MOTS-c. Many products come in variants such as different vial sizes or quantities. Pick one product, choose the variant you need, and only then add it to the cart. Changing variants after the code is applied is a different test and is not covered here.

The site has an age verification gate before the shop can be browsed, so expect that step before you reach the catalogue.

The key check is the discount line itself. Compare the subtotal, the 15% line and the total, and keep a record of each. If the code does not apply, the knowledge notes that no code applies to out-of-stock items showing a waitlist button, so confirm the product is in stock rather than waitlisted.

The knowledge leaves two points open. Whether the code stacks with sitewide sales is not stated, and the suggested method is to compare the sale price with the discounted price on your own cart. Whether specific already-discounted products accept the code is also not stated. A trial order that includes one sale item can answer both questions for your own basket.

Free shipping applies to orders over $400, calculated on the grand total before tax and shipping. Applying the code lowers the subtotal measured against that threshold, so a discounted basket may need to be larger to qualify. A small trial order will almost certainly not reach the threshold, so it tells you nothing about shipping eligibility. The example savings in the knowledge are $30 off a $200 basket and $120 off an $800 basket, which can help you estimate the discount on a larger order, but they are examples rather than a guarantee for any particular cart.

Shipping options listed are USPS Priority, FedEx 2 Day, FedEx Overnight and Saturday delivery for Friday orders. Orders placed, paid and processed before 12 noon PST typically ship the same business day, while orders after the cutoff or on weekends and holidays ship the following business day.

Every batch ships with a Certificate of Analysis from an independent CLIA-certified facility, and orders include Certificates of Analysis, HPLC purity reports and LC-MS molecular confirmation. Save these with your order record so that the trial order is documented alongside its discount line. Products are sold for in vitro scientific research and development use only and are not intended to diagnose, treat, cure or prevent any disease. Keep that use statement in your records too, so the purchase is filed under the correct purpose.
