About Us Our story & mission
Purity you can actually verify.
PeptoPharm was founded on a simple principle: researchers deserve peptides they can trust. We synthesise in the United States, purify to a 99% floor, and put every batch in front of an independent laboratory before it ships — then publish the results for anyone to see.

Our story
A US lab that
refuses to gamble.
We started PeptoPharm after spending years on the other side of the bench, tired of vials with no paperwork and purity claims nobody could back up. So we built a supply chain that is boring in exactly the right way: synthesised domestically, purified to a 99% floor, and verified every single lot by an independent laboratory.
No blending. No re-labelling. No quietly shipping the borderline batch and hoping nobody checks.
- Synthesised and filled in the United States — never drop-shipped from an unnamed source.
- Independent HPLC and mass-spectrometry verification on every single lot.
- Certificates published publicly and matched to the lot number on your vial.
- Insulated, discreet, tracked shipping on every order.
If the batch can't prove it, it doesn't ship.
Our mission
What drives everything we do.
Transparency first
Every certificate of analysis is published publicly. We believe researchers should never have to take purity claims on faith.
Uncompromising quality
We would rather destroy a batch than ship something borderline. Our 99% purity floor is a promise, not a marketing line.
Researcher-centric
We were researchers before we were suppliers. That perspective shapes every decision — from cold-chain shipping to seven-day support.
Why we do it this way
How PeptoPharm is different.
01
Third-party tested
Every single batch goes out to an independent US lab for HPLC and mass-spectrometry verification. The certificate is published before the vial ships.
02
99%+ purity floor
If a batch tests below 99% it never reaches the shelf. No blending, no re-labelling, no quietly shipping the borderline lot.
03
Cold-chain shipping
Orders placed before 2PM EST leave the same day in insulated, discreet packaging with tracking on every parcel.
04
Humans on support
A real research-support team, seven days a week, for handling, storage, reconstitution and order questions.
