PLATINUM25 is a sitewide promo code that takes 25% off the listed price of every product at Platinum Biolabs. It's the official researcher discount — direct from Platinum Biolabs, not from a third-party affiliate or influencer. See the official discount page for the canonical promo details.
Everything in the catalog. That includes:
There is no order minimum, no excluded SKU, and no product category carve-out.
Two equally valid ways:
Auto-apply link. Visit platinumbiolabs.com/?promo=PLATINUM25. A confirmation banner appears at the top of the site and the discount is locked into your cart. You can keep shopping from any page.
Manual entry. Add products to your cart, click checkout, and type PLATINUM25 in the promo code field. The 25% discount is reflected in the order total before payment.
PLATINUM25 is a limited-time promotion. We recommend redeeming it within the next week to be safe. Check the discount page for the current status — if the code is still listed there as active, it's still working.
Same reason any company does — to give people who are evaluating Platinum Biolabs a low-friction reason to try the catalog. We hold ourselves to 99%+ HPLC purity, batch-matched COAs, and fast US shipping, and the bet is that researchers who try the materials once stick around. More on the reasoning here.
PLATINUM25 doesn't compromise the experience:
You're paying 25% less for the identical product.
Q: Is PLATINUM25 a one-time-use code? A: No. You can use it on multiple orders during the promo window. Each order has the 25% applied.
Q: Can I share PLATINUM25 with a friend? A: Yes. It's a public promotional code, not a personal affiliate code. Share away.
Q: Does PLATINUM25 work on the wholesale site? A: No — wholesale has separate pricing structure. PLATINUM25 is for the retail Platinum Biolabs catalog. Wholesale inquiries should go through the wholesale flow.
Q: What if PLATINUM25 doesn't apply? A: Check that you don't already have an affiliate code in your session (look at the banner near the top of the page). If you do, removing it and entering PLATINUM25 at checkout will switch the discount.
PLATINUM25 = 25% off any order, no exclusions, valid for a limited window. Easiest way to use it is the auto-apply link. Full details on the discount page.
