FAQ
What is Blank Peptides?
Blank Peptides is a US-based supplier of high-purity peptides for laboratory research. We keep the label plain and put the budget into synthesis quality and independent analytical verification.
What are peptides?
Peptides are short chains of amino acids (typically between 2 and 50) linked by peptide bonds. They occur naturally in all living organisms and play crucial roles in biological activities, serving as signaling molecules and building blocks for proteins in clinical research models.
What are your purity standards?
Every batch undergoes rigorous analytical verification via HPLC and Mass Spectrometry. We guarantee >99% purity for all research compounds.
How long does it take to process my order?
Processing time within 1 business day. Orders placed on weekends or holidays are processed the next business day.
Are your peptides made in the USA?
Yes. Every vial is vialed, finished, tested and shipped in the USA from our own labs. We are a peptide manufacturer, not a reseller, which is why the lot number on your vial matches a certificate we can stand behind.
What does “high purity research peptides” mean on your site?
It means the brand-wide standard is >99% purity by HPLC, confirmed on every lot before it ships, with identity by mass spectrometry and a bacterial endotoxin result on the same certificate. The measured value for your lot is on its COA.
How do I order research peptides from you?
Choose the product and strength, add bacteriostatic water if you need a reconstitution solvent, and check out. Orders process within 1 business day, and the lot certificate is on the product page before you buy, not after.
Where can I buy research peptides online in the USA?
Right here. Every peptide in our catalogue is vialed, finished, tested and shipped in the USA, and you can read the lot certificate of analysis on the product page before you order. Orders process within 1 business day.
How do I choose a peptide supplier?
Look for the things that can be checked rather than claimed. A certificate of analysis for the specific lot you are buying, not a generic one. A purity figure from HPLC plus identity from mass spectrometry. Bacterial endotoxin testing, which most vendors skip. And a supplier that makes the product rather than reselling it. We publish all of that for every vial.
Do you publish a certificate of analysis for every lot?
Yes. Every lot ships with its own COA showing HPLC purity, mass spec identity and endotoxin results, and the current lot document is linked on each product page and in the COA library. The brand-wide standard is >99% purity; the number on your COA is the measured value for your lot.
Researcher Testimonies
“Ordered three times now. The COA batch numbers match the vials every time, which is more than I could say for my last supplier.”
Verified Buyer
“Exceptional consistency across multiple synthesis batches. Finally, a source that treats research as a professional endeavor.”
Verified Buyer
“Both batches I ordered came back over 99% on the independent COA. Fast processing, careful packing, zero drama.”

If you are trying to work out where to buy peptides online and every site says the same four things, here is what we would check before spending money, because it is what we check ourselves. Start with the certificate of analysis. Not a promise of one, the actual document for the lot you are about to buy, with HPLC purity and mass spectrometry identity on it and a lab you can name. Then look for bacterial endotoxin testing, which is the test most vendors quietly leave out because it costs more than the purity run. Then ask who made the vial, since a lot of peptide companies are storefronts in front of somebody else's inventory.
Blank Peptides makes what it sells. Every vial is vialed, finished, tested and shipped in the USA from our own cGMP labs, every lot carries a published COA with HPLC, mass spec and endotoxin results, and the brand-wide purity standard is >99%. The document for the current lot sits on each product page below and in the COA library, so you can read it before you buy rather than after. Orders process within 1 business day.
The catalogue is below in full: single research peptides, the blends we stock, and the supplies you will need to reconstitute them. Each name goes to the product page, and beside it you can see the current lot's purity, its lot code, the date it was tested and whether bacterial endotoxin testing is on file for that lot, with the certificate one click away. Every batch we have ever shipped sits in the COA library.
A lot of the people who land here searched for something plain: a peptide website they can trust, a peptide lab in the USA rather than a storefront, a peptide supplier or peptide source that will show its testing, or just high purity research peptides at a fair price. We are all of those things at once and we would rather prove it than say it. The catalogue you are looking at is made in a US peptide lab, every product page carries certified purity from a named laboratory, and the same batch records go to the clinics and research groups that buy from us on wholesale terms.
Ordering peptides here works the way a good peptide store should. Pick the vial, read the lot certificate, add bacteriostatic water if you need it, and the order processes within 1 business day. If you are comparing peptide vendors or peptide manufacturers in the USA, the honest test is whether they publish what we publish, and the COA library is open to anyone who wants to check.
