U.S. cGMP manufacturing with proof on every vial.
The research peptides sold here are manufactured in the United States in a certified cGMP facility, released to a >99% purity standard, and verified by accredited U.S. laboratories. Every batch receives a Certificate of Analysis — and every vial includes a QR code that opens that batch COA.
Certified cGMP facility
Produced under current Good Manufacturing Practice controls: batch records, process documentation, and quality oversight from synthesis through fill.
>99% purity standard
Research lots target greater than 99% purity by HPLC analysis — the analytical bar serious protocols expect before a compound enters the notebook.
Accredited U.S. laboratory testing
Identity and purity are verified by accredited laboratories in the United States. Independent analytics, not marketing claims alone.
Certificate of Analysis on every batch
Each production batch ships with a COA covering identity/purity verification so your lab can cite lot-level documentation.
QR code on every vial → batch COA
Scan the QR code on the vial to open the Certificate of Analysis for that exact batch — instant lot traceability at the bench.

FAQ
Frequently asked
Quick answers about ordering, shipping, and our research compounds from NIB Peptides.
Getting Started
Why do I need to register before browsing?
Because these are research-use-only materials, we ask every visitor to register a basic profile — name, date of birth confirming you are 21+, and your research role — before viewing the catalog or placing an order. It takes under a minute.
What are these products intended for?
All peptides sold here are intended strictly for laboratory and research use. They are not drugs, are not for human or animal consumption, and are not intended to diagnose, treat, cure, or prevent any disease.
Orders & Payments
Can I modify or cancel my order?
You can cancel before shipping. Once shipped, you can not cancel. Once you receive the product, if it is damaged, otherwise unusable, or missing, you have 48 hours to send us a picture of the packaging, product, and packing slip. We do not refund based on dissatisfaction from usage. We may offer a replacement.
Do you offer refunds?
Refund terms and return rules: Unused membership fees are refunded pro-rata if you cancel within the billing period. Compounded products, once shipped, are non-returnable under federal pharmacy rules.
Products & Quality
Are MyPeptide products manufactured under cGMP in the United States?
Yes. MyPeptide research peptides are synthesized and filled in a certified cGMP facility in the United States, released to a >99% purity standard, and verified by accredited U.S. laboratories. Every batch ships with a Certificate of Analysis, and every vial carries a QR code that opens that batch’s COA. cGMP refers to manufacturing process controls and documentation; analytical purity is confirmed separately via laboratory testing and batch COAs.
Are these products third-party tested?
Yes. Each peptide is tested for identity and purity, and a Certificate of Analysis (COA) is available for the products we carry. Look for the "View Certificate of Analysis" link on the product page.
How are the peptides supplied?
Most are supplied as lyophilized (freeze-dried) powder in sealed vials, intended to be reconstituted in a laboratory setting according to your own research protocol.
Safety & Storage
How should I store the product?
Follow standard laboratory practice. Most lyophilized peptides are stable at room temperature for shipping and should be refrigerated (2–8 °C / 36–46 °F) after reconstitution. Protect from light and avoid freeze-thaw cycles unless your protocol requires otherwise.
Who is eligible to purchase?
Purchases are limited to adults 21 or older acquiring materials for legitimate laboratory or research use. By registering and checking out you confirm you meet these requirements.
Shipping
How long does shipping take?
Most orders ship within 2–4 business days after the order is approved and are delivered within 2–3 business days after that, depending on your location. Tracking is emailed and posted to your portal the moment the pharmacy generates a label. Shipping is dependent upon verification of payments processed.
Are shipments discreet?
Yes. Packages arrive in plain, unmarked outer boxes with no clinical branding, no product name, and no pharmacy identifier on the exterior. The return address is a fulfillment center, not your distributor.
What happens if my package arrives damaged?
Take a photo of the packaging and the product and message your care team within 48 hours of delivery. The manufacturer will evaluate and — when the product is compromised — reship at no additional cost.
