A peptide glossary for reading product pages.
The terms that matter when you have a listing, a label or a laboratory report in front of you.
By Peptide Doctor editorial team · Updated
Start with three connections: the product name identifies what is listed, the batch ID connects the item to a production record, and the report describes tests on a sample. The definitions below help you read those details without treating marketing language as a test result.
Batch ID or lot number
An identifier assigned to a production batch. It helps connect a listing, vial label and associated documents. It is not the same as your order number, which identifies your purchase.
An exact code match matters. Similar codes or the same product name do not establish that two records refer to the same batch.
COA and HPLC
COA means certificate of analysis. It reports analytical results for a sample. Read the sample description, laboratory, date, methods and results together.
HPLC means high-performance liquid chromatography. It is a separation method used in some analytical testing. An HPLC purity figure is one result, not a blanket statement about identity, sterility or medical suitability.
Lyophilised and vial amount
Lyophilised means freeze-dried. A product described this way is supplied as a dried material rather than a ready-to-use liquid formulation.
An amount such as 10mg or 50mg describes what the listing says is in the vial. It is not a dose, schedule or instruction for personal use. Check the separate amounts of each compound when reading a blend listing.
Identity testing and purity testing
Identity testing asks whether a sample contains the intended substance. Purity testing assesses components under the method used. A report may include several methods to answer different questions.
Read which result supports which claim. A seller should be able to explain how its product description connects to the tests in the report.
Research use and product format
A research-use label describes the supplier's stated purpose. It does not establish that a product is an approved medicine or suitable for use in people.
A research vial, a combined research product and a finished cosmetic are different formats. Read the actual listing before comparing amount or price.
Straight answers
Is a batch number the same as an order number?
No. The batch number identifies a production batch. The order number identifies a customer purchase.
Does a COA guarantee everything stated on a product page?
No. It supports the results and sample described in that document. Match each product claim to a relevant test or other evidence.
What has to be visible before I pay?
Price, batch ID, COA, HPLC result, payment method, dispatch origin, and support. If those are hidden, slow down.
Is Peptide Doctor medical advice?
No. Peptide Doctor is not a clinic, pharmacy, prescriber, or medical service. Medical questions belong with a qualified practitioner.
What should I check about payment?
Read the payment methods and dispute terms available at checkout. Keep the receipt and order number. Protection depends on the provider, transaction and terms; a logo alone is not a guarantee.
Why does the batch number matter?
A COA or HPLC number is useful only when it belongs to the exact batch being sold. Generic certificates are easy to recycle.
Sources and product records
Research peptides are not approved by the TGA for human use. Product links are for checking what is visible before payment, not medical advice.
