Biolongevity Labs Coupon Code PROBIO15 Works on Both Stores: 15% Off, October 2026
Jeff Nunn tested this code on October 1, 2026.
Every compound Biolongevity Labs sells is for research use only. Ordering one does not change that, and none are approved for human or veterinary use.
PROBIO15 came off a sale-priced cart at biolongevitylabs.com on October 1, 2026, and off a second one at the Biolongevity Supplements store the same day, at 15 percent both times. It covers research peptides and bioregulators sitewide.

Biolongevity Labs Promo Code PROBIO15, Checked October 2026
Clicking the button applies PROBIO15 automatically, and the 15 percent is applied on either Biolongevity Labs or Biolongevity Supplements sites. PROBIO15 covers Biolongevity's research products across the board rather than a short list of eligible items, and the supplements store uses the same code.

Redeeming the Biolongevity Labs Discount Code
Pick a Biolongevity Store
- Our Shop Biolongevity Labs link takes you to the Labs store, where research products need an account, so register or sign in first. Vials and bioregulators are there; capsules and oral supplements are on Biolongevity Supplements, which accepts the same code.
Add PROBIO15 to the Biolongevity Checkout
- Fastest route: use the Shop Biolongevity Labs button on this page. The partner link applies PROBIO15 automatically, so the 15% is already sitting in your cart when you arrive. Prefer to type it? Drop PROBIO15 in the coupon box in the cart drawer or at checkout. The discount is applied either way, and both stores show a PROBIO15 tag once it is accepted.
See 15% Off on Sale Items Before Paying
The cart should list Coupon PROBIO15 with a minus figure beside it. If that line is missing, another code is probably sitting in the box; remove it and add PROBIO15.
PROBIO15 Verified on Both Biolongevity Stores (October 1, 2026)
On October 1, 2026, a KPV 10mg vial, marked down from $99.97 to $59.98, took $9.00 off with PROBIO15 at Biolongevity Labs, and a BioAmp bottle, cut from $299.00 to $179.40, took $26.91 off at Biolongevity Supplements. Both items were already 40 percent off.
Stacking PROBIO15 on a Biolongevity Sale
Yes. Both October test items were on sale when the code went on.
Biolongevity runs storewide promotions most months, often 40 percent off, with deeper liquidation prices on selected compounds, and the promotions need no code. PROBIO15 then comes off the reduced price.
PROBIO15 does not lapse when a sale ends; it is a permanent partner code.
Spotting a Live Biolongevity Promotion
A live sale shows as a crossed-out price on the product and again in the cart, before any code is added.
Biolongevity Labs and Biolongevity Supplements: Which site to order from
Biolongevity Labs now sells across two storefronts. Research peptide and bioregulator vials are on biolongevitylabs.com. Biolongevity Supplements at biolongevitysupplements.com is the wellness-focused storefront carrying the oral range. The bioregulator and peptide capsules have moved there from the Labs site.
If you are looking for Khavinson bioregulator capsules or oral peptide supplements, that is the Biolongevity Supplements site. The Labs site links straight through to it from the Orals menu, so you don't need to search for it separately.
The October 1 carts confirmed PROBIO15 in both stores, vials and capsules alike.
Biolongevity Labs Shipping Rates and Free Delivery Over $400

Faster services, FedEx 2 Day and Next Day, can be selected at checkout, and tracking information arrives in the confirmation email.
| Option | Transit | Notes |
|---|---|---|
| Free standard shipping | Orders over $400 | Grand total before tax and shipping |

Why the $400 Free Shipping Total Comes Before Your Discount
Free standard shipping applies to orders over $400, calculated on the grand total before tax and shipping.
The free-shipping bar measures the subtotal before PROBIO15 comes off. In the October 1 Labs cart, a $59.98 item showed $340.02 left to reach free shipping, the same gap with or without the code, so the discount never pushes you back under $400.
Biolongevity Cold-Pack Shipping Option
Biolongevity sells a cold pack as an add-on ($9.99, on sale at $5.99 on October 1) for lyophilized peptides shipped in hot weather. Pair it with fast shipping so it is still cold when the box arrives.
Biolongevity International Orders
Biolongevity ships worldwide and includes customs and import paperwork for selected countries. Duties, taxes and local import rules are the buyer's responsibility.
Other Biolongevity Savings and Offers
PROBIO15 is the standing discount, but it is not the only one available.
- Newsletter subscribers get sign-up incentives from Biolongevity: a first-order discount, early access to new products and subscriber pricing.
- Volume discounts appear on Biolongevity product pages, and larger bulk orders are priced by email.
- An SMS list sends early launches and insider deals.
What Biolongevity Does When an Order Goes Wrong
Biolongevity Labs publishes a Refunds & Returns page, and it says two different things. It opens by stating the company cannot accept returns because of its quality-control standards and the fragile nature of its products. Further down, the same page accepts unopened products within 10 days of delivery, less a 15 percent restocking fee and the cost of the return label. If an order arrives with missing, incorrect, or damaged items, the page directs customers to email help@biolongevitylabs.com. Customers must request cancellations by email before the order ships. Because the policy contradicts itself, confirm eligibility with Biolongevity support before relying on a return, and read the current terms on the Refunds & Returns page.
Biolongevity Payment Options, Including Klarna and Amex
Biolongevity accepts all major credit cards, including American Express, plus Klarna buy-now-pay-later and bank payments through LinkMoney. The Amex and Klarna options arrived in late September 2026.
How the Biolongevity Code Gets Tested on Both Stores
Once a month, Jeff Nunn adds a product to a Biolongevity cart, applies the Project Biohacking partner code PROBIO15, and saves the order summary, and the date on this page only moves after that.
October's carts were built on October 1, 2026, one on each store. Should a check fail, PROBIO15 is pulled from the page.
How Biolongevity documents each lot, and what its certificates show, is set out in our

Biolongevity Labs is rated on fixed, published weights shared by every vendor we list, explained on the

Biolongevity Labs is not Longevity Labs
These are two unrelated companies with similar names, and search results mix them constantly.
Biolongevity Labs sells research peptides, bioregulators, and supplements at biolongevitylabs.com. It was co-founded in late 2024 by; Jay Campbell, Josh Felber, and Hunter Williams. Naming the people behind the company is rare in this category. Most research peptide suppliers publish an address and a contact form and nothing more, which has anyone purchasing research compounds guessing who they are dealing with.
Longevity Labs is a separate supplement brand sold through The Feed. PROBIO15 does not work there. If you arrived looking for a Longevity Labs discount, this is not the same company.
PROBIO15 passed both October 1, 2026 checks. Add it at checkout and it comes off any storewide sale already running.
Coming back later, enter PROBIO15 at checkout. The same discount is applied automatically once the code is accepted.
