Background
Black Friday peptides: what is on offer?
Updated: November 5, 2026
For Black Friday 2026, BergdorfBio bundles six research items: Retatrutide, Tirzepatide, GHK-Cu, BPC-157, the Glow Stack and bacteriostatic water. The selection follows paid sales and current availability.
Prices come from Saleor and are not maintained separately on this page. The landing page therefore shows the same price as the product page and checkout. The sale price applies from November 25 for registered newsletter subscribers at checkout and from November 27 to everyone, for each product while the promotional quantity lasts.
The promotional quantity is limited per product. Once it is used up, the product returns to its regular price. Signing up for early access reserves neither a price nor a promotional quantity.

Single pack
For a first order or for restocking one specific strength.
The card price refers to the cheapest available variant.
Multi-pack
Several packs in one order, with the quantity price stored in Saleor.

From November 25 to 30, 2026. On November 25 and 26 it appears at checkout for addresses registered for the newsletter; from November 27 it is open to everyone. For each product the sale price applies while the promotional quantity lasts.
Is Retatrutide part of the Black Friday offer?
Retatrutide is part of the selection. The product page price, which comes directly from Saleor, shows whether a sale price is active. Once the promotional quantity is used up, the regular price applies again.
Do I need a discount code for Black Friday?
No code is needed for the campaign: the sale price appears at checkout as soon as you enter your newsletter email address. Partner and points codes can be combined with the sale price. Other vouchers, such as the welcome voucher, do not apply to campaign items.

The promotional quantity is limited per product. Once it is used up, the product returns to its regular price, even while the campaign is still running.

Why is my voucher not applied?
With campaign items in the basket, checkout accepts only partner and points codes. Welcome, referral, recovery and support codes are rejected then. For items without a sale price they apply as usual.
Does signing up reserve a price or a promotional quantity?
No. Signing up sends the access email but reserves neither a price nor a promotional quantity.

The $250 threshold applies to the merchandise value after the discount. Below that, shipping is $9.99.
What happens to prices after November 30?
