What is the Biolongevity Labs coupon code?

The Biolongevity Labs coupon code is PROBIO15. It takes 15% off research peptides and bioregulators sitewide and was verified active by Project Biohacking in August 2026.

How do I use PROBIO15 at Biolongevity Labs?

Add your items to the cart at biolongevitylabs.com, paste PROBIO15 into the discount code field at checkout, and confirm the 15% appears in your order summary before paying.

Does the Biolongevity Labs code give 15% off?

Yes. PROBIO15 takes 15% off and applies on top of any automatic storewide sale price. Only one coupon code can be entered per order, so a second code is an alternative rather than an addition.

Is PROBIO15 an official Biolongevity Labs promo code?

Yes. PROBIO15 is the official Project Biohacking partner code for Biolongevity Labs, issued through our affiliate relationship with the vendor and re-verified monthly.

How does Project Biohacking verify the Biolongevity Labs coupon code?

We also review the vendor's certificate of analysis documentation separately, which is covered in our Biolongevity Labs review.

Biolongevity Labs Coupon Code PROBIO15: 15% Off August 2026

PROBIO15 is the official Project Biohacking partner code for Biolongevity Labs, and it applies across their research products rather than to selected items. It is the same code whether you searched for a Biolongevity Labs coupon code, a discount code, a promo code, or Biolongevity Labs coupons, and whether you write the name as Biolongevity Labs, Bio Longevity Labs or biolongevitylabs. There is one active code, and this is it.

Project Biohacking earns a commission when you order through this link. That does not change your price, and it does not affect which vendors we review or how we rate them.

How to use the Biolongevity Labs discount code

Open Biolongevity Labs

Use the link above to open biolongevitylabs.com. Vials and bioregulators are on the Labs site. Capsules and oral supplements are on the supplements site, and the code works on both.

Enter PROBIO15 at checkout

Add your research compounds to the cart and paste PROBIO15 into the discount code field at checkout.

Confirm the 15% before you pay

Check that the discount has been applied to your order summary before you complete the purchase. If the code did not take, the most common reason is a competing code already in the field.

Does PROBIO15 stack with Biolongevity Labs sales and promotions

Yes, and this is where the code is worth the most.

Biolongevity Labs runs regular promotions: automatic storewide sales with reduced prices marked on the product, and periodic offers on selected compounds. These apply at the cart rather than being entered as codes, and PROBIO15 applies on top of them.

So during a sale, you take the sale price and then 15% off with PROBIO15.

What does not stack is a second coupon code. There is one code field and one entry per transaction, so if you are holding another Biolongevity Labs promo code you are choosing between them, not combining them. PROBIO15 is the one to enter.

PROBIO15 is a standing code rather than a limited-time promotion, so it does not expire between sales.

Biolongevity Labs and Biolongevity Supplements: which site to order from

Biolongevity Labs now sells across two storefronts. Research peptide and bioregulator vials remain at biolongevitylabs.com. Biolongevity Supplements at biolongevitysupplements.com carries the oral range, and 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 do not need to search for it separately.

Project Biohacking has confirmed PROBIO15 applies on both, so the same code works whether you order vials or capsules.

Option	Transit	Notes
Free standard shipping	Orders over $400	Grand total before tax and shipping
USPS Priority	Varies by destination	Varies by destination
FedEx 2 Day	2 business days	After processing
FedEx Overnight	Next business day	Signature Required option available
FedEx Saturday Delivery	Saturday	Friday orders placed before 12 PM PST

The $400 threshold and your code

Free standard shipping applies to orders over $400, calculated on the grand total before tax and shipping.

PROBIO15 comes off before that calculation, so the threshold is measured on your discounted total. A cart at $420 becomes $357 after the code, which means about $50 more gets you across the threshold and a larger order shipped free

Worth knowing if you were already planning a second vial. Compare on cost per milligram, not sticker price. Vial sizes differ between suppliers and a cheaper vial is often a smaller one.

Cold-pack option

For lyophilized peptides ordered during periods of extreme heat, a cold-pack option is available at checkout for a small added charge. It requires Next Day shipping to remain effective in transit, so budget for both.

International orders

Biolongevity Labs ships internationally. You are responsible for customs duties, taxes and local import compliance. Supporting documentation including certificates of analysis, MSDS and research-use declarations can be included on request.

Loyalty points, referrals and other ways to save

PROBIO15 is the standing discount, but it is not the only one available.

Loyalty points accrue on every purchase and are redeemable against future orders.
The referral program gives savings to both the referring and the referred researcher on qualifying orders.
Newsletter subscribers get early access to new product launches, coupon codes and limited-time promotions.
Student and military discounts are available for verified university students and active or veteran military members.

Returns and order problems

Biolongevity Labs does not publish a returns policy. There is no stated window, no return form and no refund schedule anywhere on the site.

What its terms do say is that if you have a problem with an order, billing or delivery, you contact customer support first, and that the company will investigate and may offer a shipping investigation, a replacement or a refund where appropriate.

That is a discretionary process rather than a policy you can hold them to. It is not unusual in this category, but it does mean the outcome depends on the conversation rather than on a published rule. Check your order against the confirmation the day it arrives and raise anything wrong immediately, while the delivery is fresh and the evidence is easy to produce.

How Project Biohacking verifies this code

Project Biohacking checks the Biolongevity Labs coupon code at the beginning of each month by confirming it has not expired in the vendors partner dashboard and checking it on Biolongevity Labs site. PROBIO15 was last confirmed active on August 1, 2026.

We publish the verification month in the page title and in the heading above the code so you can see how current the check is before you rely on it. If a code stops working, it comes off this page rather than sitting here as a dead listing.

Biolongevity Labs publishes lot-specific certificates of analysis for its research peptides through MDx BioAnalytical Laboratory, with BioRegen reports covering earlier batches. Every vial label carries a QR code that opens the product page, where the certificate of analysis for that lot is published. The lot number is printed on the same label, so the vial in your hand can be matched to the certificate for that batch rather than to a general library. Our full analysis of what those certificates actually show is in the Biolongevity Labs testing and COA review.

Project Biohacking scores Biolongevity Labs against a published rubric with named criteria and fixed weights, the same one applied to every supplier in the directory. The criteria, the weights, and the rule for what happens when a document cannot be assessed are on the rating methodology page.

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.

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.
