YGIS supplies research peptides to laboratories that need certainty, not claims. We source to specification, verify every lot, and document exactly what we ship.
Why we exist
YGIS exists to make peptide sourcing predictable. Every lot is synthesized and released by GMP-equivalent partners against a written specification: confirmed identity, quantified purity, and a complete analytical record.
We sell direct, with no rebranders or middlemen between the lab and the lot. The result is reference-grade material with documentation you can audit.
What we do
We work as a sourcing and QC partner: catalog compounds for routine research, and custom synthesis for novel sequences. Every route is documented, every batch is released against spec, and every order ships once released.
Documentation
No black boxes: each lot carries a certificate of analysis, a chromatogram, and a mass confirmation. If the paperwork is not complete, the lot does not ship.
HPLC · MS · KF · endotoxin
“If a lot can’t be verified, it doesn’t ship.”
YGIS quality standard
The standard
Every compound follows the same documented path — from synthesis to the vial in your lab.
Traceable raw materials, controlled conditions, documented routes.
Multi-pass purification to a >99% floor.
Identity by mass; purity by chromatography.
Shipped only after release; in-stock orders ship in 10–18 days.
Commitments
Every lot released against HPLC and mass-spec data. The number on the spec is the number in the vial.
Lot numbers link to raw materials, synthesis records, and QC data — auditable end to end.
Shipped worldwide in 10–18 days for in-stock items; out-of-stock orders fulfilled within 28 days.
No therapeutic claims, no off-label suggestion. Research-use-only, stated plainly.
Novel sequences and scale-up handled with the same QC discipline.
Technical questions answered by people who understand the chemistry and the documentation.
