FOR RESEARCH USE ONLY!  NOT FOR HUMAN OR VETERINARY USE

We sell peptides. We ship proof.

GreySyn was built for researchers who are tired of choosing between ordering blind and paying massive markups.

Our mission

Precision peptides, without the pricetag

Reproducible research starts with peptides that are pure and affordable. Too many suppliers ask you to pay high prices for high purity – we think purity should be standard.

From our facilities in Tampa Florida, GreySyn pairs high-purity research peptides with independent testing and clear documentation, then we price them so you can take on ambitious research endeavors.

What we hold to

Four standards behind every vial

Purity you can prove

We publish a measured purity figure for every compound and back it with a third-party COA — no rounding up, no vague claims.

Traceable by design

Each vial carries a lot number that links to its certificate, so results in your notebook trace back to a specific batch.

Fair pricing

Research budgets are finite. We list transparent prices and keep them low so quality reagents stay within reach.

Responsible supply

All products are strictly for laboratory research use and labeled accordingly. We ship to qualified researchers only.

American owned, america based

Our quality process

How a compound earns a place in the catalog

Nothing goes live until it clears each step. The same discipline applies to every lot, every time.

1

Sourced & synthesized

Compounds are synthesized to the target sequence and lyophilized into single-use vials.

2

Independently tested

A third party US lab runs HPLC for purity and mass spectrometry to confirm identity.

3

Documented

Results are issued as a lot-specific Certificate of Analysis and added to our COA library.

4

Released

Only lots that meet our purity threshold are listed and held in cold-chain storage until they’re shipped fast and free to you.
