Your source. Verified.
BioPeptides exists for researchers who refuse to compromise on purity, documentation or reliability. We're not the biggest — we're the most rigorous.
What you receive with every order
A certificate of analysis tied to the batch number printed on your vial — the same one shown on the Lab results page.
Full traceability
Unique batch number, analysis date and laboratory.
Documented tests
Purity by HPLC and identity by mass spectrometry.
Available
CoAs are publicly accessible on the Lab results page.
Our principles
Verification first
Every compound in our catalogue is independently tested by a third-party lab before we offer it. We publish the certificate of analysis for each batch. If a compound can't be verified, it doesn't go on the shelf.
Speed, no shortcuts
Every order is carefully prepared and shipped in a discreet parcel with tracking. We don't trade handling standards for speed — we simply built a process that requires no compromise.
Transparency by default
No vague purity claims. No opaque suppliers. No hidden fees. Every product page states exactly what you get: purity percentage, molecular weight, batch number, storage conditions and a direct link to the certificate of analysis.
Our method
Source
We work with established manufacturers that meet our documentation and testing requirements. Every supplier relationship is assessed before a single vial enters our catalogue.
Verify
Every batch undergoes independent third-party analysis — HPLC for purity, mass spectrometry for identity confirmation. We test what matters: purity, endotoxins and heavy metals.
Document
The certificate of analysis is generated, published and linked to the product before it goes live. No exceptions.
Deliver
Shipped in a discreet parcel with tracking. Indicative delivery time: around 8 days.
Supply chain
From our laboratory to your door: traceability at every step.
Partner laboratory
Batch synthesis and analysis by our partner laboratory.
Control & certificate
Each batch is validated (HPLC, mass spectrometry) and its CoA numbered before release.
Tracked shipping
Departure from the laboratory in a discreet parcel, with a tracking number provided.
Delivery in Europe
Transport to your address in Europe. Indicative time ≈ 8 days.
What we get asked most
The recurring questions about quality and control.
How do I check that the CoA matches my batch?
Are your peptides pharmaceutical grade (GMP)?
Why state ≥ 99% and not 99.9%?
What happens if a batch fails control?
Are your tests outsourced or in-house?
How are the products shipped?
