Documentation & compliance

Built for
compliance.

Every order from Classic Peptides ships with complete documentation. We take compliance seriously because researchers depend on it.

Our compliance pillars

Four commitments on every order.

Certificate of Analysis

Every product ships with a full COA from our independent testing partner. The COA includes HPLC purity percentage, mass spectrometry identity confirmation, lot number, and testing date — not a summary, the actual laboratory document.

Issued by: independent third-party laboratory
Includes: HPLC % purity, ESI-MS identity, lot number, date
Availability: Download on product page + included with every shipment

Third-party verification

We require third-party testing for every supplier's own test results. Purity and identity are confirmed by a laboratory that has no commercial relationship with our synthesis partners — an independent check that protects our customers from conflicts of interest.

Standard: independent third-party testing
Method: HPLC-UV (purity) + ESI-MS (identity)
Threshold: ≥98.0% purity — rejection below this level

Cold-chain handling

Peptides are sensitive to temperature. Our compounds are stored at −20°C under continuous monitoring from receipt through dispatch. Shipments include appropriate cold-chain packaging and handling instructions.

Storage: −20°C, continuously monitored
Shipping: Cold-pack protocol, insulated packaging
Documentation: Temperature log available on request
§

Compliance FAQ

Common questions.

Is it legal to buy research peptides?+

In the United States, research-grade peptides are legal to purchase for legitimate in vitro research purposes. Buyers are responsible for compliance with applicable laws in their jurisdiction. Our products are sold with clear research-use-only labeling and require buyer confirmation of qualified researcher status.

What does the COA contain?+

Our Certificate of Analysis is the complete output document from our independent third-party testing laboratory. It includes: HPLC purity percentage, ESI-MS identity confirmation, lot number, compound name and CAS number, testing methodology, and testing date. It is not a summary — it is the actual laboratory document.

What happens if a lot fails testing?+

Any lot that tests below ≥98.0% purity is rejected and does not enter our inventory. It is never offered for sale. There are no exceptions and no alternative "standard grade" — our threshold is non-negotiable.

Can I use these compounds for human administration?+

No. All products sold by Classic Peptides LLC are for in vitro research use only. They are not approved by the FDA for human use and are not intended for diagnostic, therapeutic, or any other use in humans or animals. By purchasing, customers confirm they understand and agree to this restriction.

Do you have a Safety Data Sheet for each compound?+

Yes. Safety Data Sheets (SDS) are available for all compounds in our catalog. They can be downloaded from each product page or requested by contacting us directly at info@classicpeptides.com.
