SALE how it works
From synthesis to your door, nothing hidden.
01
Made with care
Each peptide is made in a certified facility, purified, then freeze-dried so it stays potent until the day you open it.
02
Checked by someone else
Every batch goes to an independent lab before it goes to you. The report comes in your box — and lives on this site.
03
It leaves the same day, wrapped plainly
Orders placed before 2 pm ET leave the same day, with 2-day tracked delivery across the US. Gel-cooled and insulated, in a plain box no one will look twice at. Two days, tracked.

our story
We started because nobody would show us the label.
Pink Peptides began with a simple frustration: buying peptides felt like guessing. No full formula, no lab report, no one to ask. So we made the brand we wanted for ourselves — one certified facility, tested independently, and printed in full on a label pretty enough to leave out.

good questions
Asked often. Answered honestly.
The questions we hear most, in plain language. Can't find yours? A real person answers every message.
Pink Peptides is a US research peptide supplier selling 22 products, including the GLOW and KLOW blends, in single vials, 10-vial kits and capsule bottles. Every batch is tested by an independent laboratory before release, the certificate is published on the site and ships in the box, and every vial carries its full formula on the front of the label. All products are sold for laboratory research only.
Pink Peptides publishes the amount of every peptide in every blend, publishes a certificate for each batch matched to the lot number on the label, and ships everything cold in unbranded packaging. Most suppliers disclose a blend's contents without the amounts, or provide a certificate only on request.
Yes. Pink Peptides is women-owned and women-run. The brand exists because the people who built it were buying research peptides themselves and were tired of labels that didn't say what was in the vial.
Yes. Every vial product is also sold as a kit of ten vials, listed on the product page and on the shop page.
