Documented Supply
Peptides With a Certificate of Analysis
A batch-specific COA with every order — identity and purity you can verify.
A Certificate of Analysis is the document that describes exactly what is in a given batch. Every single-compound peptide we supply ships with its batch COA, and recent certificates are published in the COA library so you can verify identity and 99%+ HPLC purity before and after you order.
Our research-supply standards
99%+ HPLC Purity
Every batch is verified by high-performance liquid chromatography. The measured purity figure is recorded on the batch COA — not a marketing claim.
COA With Every Order
A batch-specific Certificate of Analysis ships with every order. Sample COAs are accessible from the COA library before you order.
Tracked US Delivery
Every order ships on a tracked service with delivery across the USA in 2–3 business days — you get a tracking link as soon as it dispatches.
Research-Only Supply
All compounds are supplied strictly for in-vitro laboratory research. Documentation, labelling and packaging reflect that restriction.

Why MY PEPTIDES for US research supply
A purity claim with no paperwork behind it is just marketing. A Certificate of Analysis turns that claim into something you can check: it names the compound, records the HPLC-measured purity for a specific batch, and carries a batch or lot number you can match against the label on your vial.
We ship the batch COA with every single-compound order and publish recent certificates in the COA library, so the documentation travels with the product rather than living only on a marketing page.
How to read a Certificate of Analysis
Start at the top: confirm the compound name matches what you ordered, then check the batch or lot number against your vial label so the paperwork and the product belong together. The headline purity figure is the HPLC result for that specific batch.
Recent COAs for each product sit in the COA library, and the batch-specific certificate ships with the order — so you can cross-check before and after delivery rather than taking purity on trust. All material is supplied for in-vitro laboratory research only.
Frequently asked questions
- What does a Certificate of Analysis show?
- For a specific batch: the compound identity, the HPLC-measured purity figure, and related analytical results. The batch/lot number on the COA matches the label on your vial.
- Can I see a COA before ordering?
- Yes. Recent batch COAs for each product are accessible from the COA library on this site.
- Is the COA from an independent lab?
- Certificates are issued by the testing laboratory for each batch — the COA that ships with your order corresponds to that specific batch.
- What purity do the COAs report?
- Single-compound peptides are HPLC-verified at 99%+, with the exact measured value recorded per batch.
- Do stacks and accessories have a COA?
- Single compounds each carry a batch COA. Multi-compound stacks and accessories (e.g. the pen) are documented on their own product pages.
