Research-grade peptides
Every lot, on the record.
Lot-tracked research compounds. Every vial carries a lot number you can check against its published Certificate of Analysis.
The standard
Three things every order carries.
-
Third-party tested
Every production lot goes to an independent third-party laboratory for identity, purity and content testing before it’s listed. The certificate names the methods the laboratory used.
-
A certificate for every lot
The full report is published on the product page before a vial from that lot ships, and every vial carries its lot number.
-
Shipment protection
Every order ships with protection included. If a package is lost, stolen or arrives damaged, we reship it at no cost.

Certificate of analysis

Read the report, not a summary of it. Each product page carries the full certificate for the lot currently shipping: the laboratory, the date, the methods, the measured amount and every result, with the original PDF and every earlier lot.

Questions
Before you order
Who can buy from Ledger Aminos?
Adults 21 and older purchasing for laboratory research. Every order requires a research-use attestation at checkout.
How do I match my vial to its certificate?
Find the lot number on the vial label, such as LA-0001, then open that product’s page. The certificate for the current lot is shown there, with earlier lots listed under lot history.
Who tests your products?
Every lot is tested by an independent third-party laboratory. Identity is confirmed against a reference, usually by LC-MS, and purity or content is measured, usually by HPLC. Each certificate names the laboratory and the methods it used.
Why does a report name another company as the client?
Some current lots were tested by an independent laboratory on our supplier’s or a testing group’s commission; the report is published exactly as the laboratory issued it, with its verification key. Lots from our own orders are tested under the Ledger Aminos name with identity, purity, amount, endotoxin, sterility, heavy metals and a fentanyl screen.
Do you provide dosing or preparation guidance?
No. Our products are sold for laboratory research only, and we don’t provide guidance on use in humans or animals.
When will my order ship?
Orders placed by 2:00 PM CT on a business day ship that day. Product pages and checkout show the cutoff countdown and the estimated arrival for each shipping option.
What if a lot doesn’t match its certificate?
Contact us within 14 days of delivery with your order and lot number. We review every report within 3 business days, and when a lot issue is confirmed we replace or refund the product. Our returns and replacements policy has the details.
