Sale Terms: Buy One, Get One 50% Off

How it works: when your cart contains two units of the same product in the same size, the second unit is 50% off. The discount is applied automatically at checkout. No code is needed.

Every pair counts. For example, 2 vials = 1 at half price, 3 vials = 1 at half price, and 4 vials = 2 at half price.

Both units must be the same product and the same size (for example, two GLP3-RT 10mg vials). Different products or different sizes do not pair together.

Kits are excluded, since they are already discounted bulk pricing.

You can still use one discount or referral code per order. The code is applied after the sale price.

Free standard shipping ($200+) and sales tax are calculated on your total after the sale discount.

The sale applies only to items that are in stock. TX Peptide Supply may change or end this sale at any time; orders already placed keep the price shown at checkout.

All products are sold strictly for laboratory research use only. Not for human consumption.
