FAQ

About these deals

What counts as a deal?

A sale price shown on the vendor's site, a price at least 5% lower than at our previous weekly check, or one of our discount codes. Each deal shows which one applies.

How often does this page change?

Every 7 days, after our weekly price check. Deals that ended drop off and new ones are added.

Are these the cheapest peptides?

Not always. A deal is a discount on that vendor's normal price. To compare vendors, use the price index, which ranks every vendor by price per mg.
