I’ve been pretty vocal about sales. When a shop runs 50% off, my first thought is “so you’ve been overcharging me this whole time?”
That’s why we price the way we do. Look us up on just about any price aggregator and you’ll find us in the top 3, whether it’s a single vial or a 10-pack. Good value every day is the whole idea.
I’ll be honest though: sales move the needle like nothing else. We have employees who count on us, a lot of inventory on the shelves, and we’re trying to run a good business while it's still a thing.
So we’re running 10% off until we hit our October sales goal. Hitting your goals is good. We’d like to hit ours, and we’d love your help doing it. Sale stacks with your reward points, affiliate codes and everything else. No code needed.

Wondering about the shirts @PeptideSupplyCo mentioned for affiliate partners back in July 😬

Almost every single company is not actually sticking to the "For Research Use Only" model. Selling peptides and talking about your n=1 experiments with them is a one way ticket to getting bent.
Saying not for human consumption and then blatantly talk about how great they are for human consumption is a short term, risky business model.
Disclosure: PeptideBenchmark's owner operates Aperture Clinic. It is never scored, ranked, or listed here, and every link to it on our site is labeled. What that means and the rules we hold ourselves to: peptidebenchmark.com/blog/we…
Aperture Clinic is open.
Physician-guided peptide care. Online intake, licensed clinician review, prescriptions filled by licensed U.S. pharmacies and shipped to you.

The Labor Day Sale is live at PeptidePlugs. 15% off everything through Monday night. No code, the discount lands in your cart automatically.
And if you ordered today before the sale dropped, go check your email. We added store credit to your account so you didn't miss out, and yes, it stacks on top of the 15%.
Long weekends are for stocking the lab.

Labor Day is the holiday about work. We run a workshop. Seemed right.
15% off sitewide through Monday night. It's already on the price — no code to enter, nothing to remember.
Volume Pricing and affiliate codes come off on top of it. Three separate discounts, and they compound: up to 31% off.
Every published batch is independently third-party tested, with its COA available before it ships. New batches now carry heavy-metal screening by ICP-MS.
Texas-built. Research-Focused. Research use only.
Ends Monday at midnight. Link in bio.

We have some of the best prices on tesa and tesa/ipa and our other blends.
Shipping the very best peptides, today!

sorry y'all. I forgot I was going to start permanently decreasing prices. Glow and Klow now 20% cheaper forever. We're going to have a big BPC surprise next week.
Reptides sells “we take $0 from suppliers” while pitching a $1k clinician chatbot that surfaces “what the community reports,” and co-founders join Forum threads that read like personal protocol talk.
Independence from vial money ≠ a researcher-only product surface.
