Asked often. Answered honestly.

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.

Yes. The current certificate for every formula is published on the Pink Peptides lab reports page, searchable by formula or lot number, and can be read before ordering.

A certificate of analysis, or COA, is a laboratory report for a specific batch of material. It states what the material is, how pure it is, and what else the laboratory found. A COA applies only to the lot it names, which is why the lot number on a vial should match the certificate.

Three results matter most. Identity, usually by LC–MS, confirms the molecule's mass matches the label. Purity, usually by RP-HPLC, shows what percentage of the material is the peptide itself. Endotoxin, by LAL assay, screens for bacterial contamination. Net peptide content is also worth checking, because it tells you how much peptide is in the vial rather than how much powder.

Yes. Every Pink Peptides vial carries a lot number on the label that matches its published certificate, and a printed copy of that certificate ships in the box.

Yes. Pink Peptides keeps every certificate. Send the lot number from the label through the contact form and we will email the PDF.

A batch that does not meet the ≥ 99% purity specification is not released for sale.

Every batch is tested by an independent laboratory before release. Identity is confirmed by LC–MS, purity by RP-HPLC against a ≥ 99% specification, water content by Karl Fischer titration, and endotoxin by LAL assay.

No. Pink Peptides accepts guest checkout, and an account is created from the order so you can track it and download certificates later.

Peptides are sensitive to temperature and light, so Pink Peptides cannot accept returns once an order has shipped.

Send a photo of the box and vial through the contact form within 48 hours of delivery. Pink Peptides replaces the item, with nothing to send back.

Research use only means a product is sold for laboratory research and in-vitro experimentation by qualified professionals. It is not a drug, food, cosmetic, supplement or medical device, it has not been approved by any regulator for human or veterinary use, and it must not be administered to humans or animals.

No. Nothing Pink Peptides sells is approved by the FDA or any other regulator for human or veterinary use. These statements have not been evaluated by the Food and Drug Administration. Our products are not intended to diagnose, treat, cure or prevent any disease.

Research compounds are sold legally for laboratory use in the United States, but the rules differ by compound and by jurisdiction, and some compounds are controlled in some countries. You are responsible for confirming what is lawful where you are before ordering. Pink Peptides cannot give legal advice.

Orders are accepted from buyers aged 21 or over who confirm at checkout that the products are for laboratory research only. Pink Peptides may refuse or cancel any order.

No. Pink Peptides does not provide dosing, administration, reconstitution amounts, protocols or any usage guidance, and our support team will not answer those questions. We can help with product specifications, certificates, storage, shipping and orders.

Orders placed before 2 pm ET on a business day leave the same day. US delivery is 2-day tracked, and every order ships gel-cooled in an insulated mailer.

Yes, Pink Peptides ships internationally to most destinations. Delivery times vary by country and are longer than domestic orders. Customs rules for research compounds differ from country to country and can change without notice, and it is the researcher's responsibility to know what may lawfully be imported into their own jurisdiction. Pink Peptides cannot advise on local import rules, and a package held or refused by customs is outside our control.

Tracking is emailed when an order ships, and can take up to 24 hours to start updating. Orders can also be tracked on the Track order page using the order number and the email on the order, with no account needed.

Sealed lyophilised vials are stored at 2–8 °C, protected from light. For longer storage they can be frozen. Pink Peptides vials carry a 24-month shelf life sealed at 2–8 °C, and each order includes a storage card with the details for that vial.

Once a vial has been reconstituted, it is kept refrigerated and used within 28 days. Repeated freeze-thaw cycles are avoided, because they degrade peptides.

Lyophilised peptides tolerate short periods at room temperature, which is why they are shipped freeze-dried. The cold chain protects the material over the whole journey rather than any single hour. If the gel packs were fully thawed and the box was warm on arrival, send a photo within 48 hours and Pink Peptides will replace it.

Most Pink Peptides products are a white lyophilised cake. GLOW and KLOW have a blue tint, which comes from the 50 mg of GHK-Cu in each vial. A cake that has shifted or cracked in transit is normal and does not indicate a problem.

That is a desiccant pack, which keeps moisture away from the sealed vial. It is not part of the product.
