About us
Measured to the molecule.
Methode Sciences supplies research peptides the way a laboratory would want to receive them: independently tested, fully documented, and shipped from the US with the certificate already published.
Our reason for being
The number on the label should be a number, not a promise.
Research compounds are only as useful as the confidence you can place in them. Too much of this market runs on claims — "99% pure," "lab tested" — with nothing behind the words.
We started Methode Sciences to remove the guesswork: every lot we sell is analyzed by an independent laboratory before it's listed, and the report is public before the first vial ships. You don't have to trust us. You can check.
How we work
The Methode Standard
Independent verification, every lot
No lot reaches the shelf without a sample going to an independent, US-based analytical laboratory. Identity is confirmed by LC-MS; purity is measured by HPLC. If the result falls short of our threshold, the lot is rejected — not relabeled, not discounted.
Published before it ships
The Certificate of Analysis for each lot is posted to our Lab Results page before that lot goes on sale. The lot number on your vial matches the document online, so you can confirm that what you received is what was tested.
Manufactured to a standard
Our compounds are synthesized in ISO 9001:2015-certified, GMP-compliant facilities, then verified again by a lab that has no stake in the outcome.
Honest presentation
We don't inflate purity figures, round up, or publish "typical" values. The COA shows the measured result for that lot, whatever it is.
What to expect
Procurement & Fulfillment
US-based support
A real team answers email at info@methodesciences.com seven days a week — for order status, COA questions, documentation requests, and institutional purchasing.
Fast, tracked dispatch
Orders paid before 12:00 PM PST on a business day leave within 24 hours. Most arrive in 2–3 business days with full tracking at every step.
Packaging built for stability
Lyophilized vials ship in insulated, protective packaging that guards against impact and light through domestic transit.
Everything in the US
Testing, fulfillment, and support are all handled by US facilities and US staff. Nothing about our supply chain is outsourced overseas.
What we stand behind
Our Commitment
Methode Sciences exists to support rigorous in-vitro research with materials that can withstand scrutiny. That means analytical verification instead of assurances, transparency instead of marketing, and a support team that helps with procurement rather than steering you toward a sale. We supply research-grade peptides for laboratory investigation only, and we hold every lot to the same standard whether it's our best seller or a compound we ship twice a year.
Common Questions
How do I know a vial is authentic?
Every vial is labeled with the compound name and its lot number. That lot number corresponds to a Certificate of Analysis on our Lab Results page showing the identity and purity results for that exact batch. If the numbers match, the vial you're holding came from the lot that was tested. If a lot number doesn't appear in our records, contact us before use.
Who performs the testing?
Freedom Diagnostics, an independent US analytical laboratory with no financial connection to Methode Sciences. Testing covers identity by LC-MS and purity by HPLC, with net content and endotoxin (LAL assay, USP <85>) also reported. Results are published for every lot.
How long do the compounds stay stable?
Sealed lyophilized vials remain stable for up to 24 months when stored at −20 °C. Refrigerate at 2–8 °C on arrival and for short-term storage, protected from light and moisture.
How are orders packaged?
Compounds are supplied as freeze-dried powder, most in 3 mL clear glass vials, packed in a reusable magnetic case inside insulated protective packaging.
When will my order ship?
Orders paid before 12:00 PM PST on a business day dispatch within 24 hours; later orders and weekend orders ship the next business day. You'll receive tracking by email and in your account as soon as the package is with the carrier.
What can support help with?
Orders, shipping, tracking, COAs, and institutional procurement. Our team does not provide protocols, usage guidance, or answers to questions about administration in humans or animals — this is a firm policy.
