Vitrapept supplies research peptides, proteins and amino-acid derivatives for laboratory research. Everything we sell is sourced from verified research manufacturers under strict quality control, from synthesis through to packaging.
The research space has a trust problem: too many suppliers, too little proof. We built Vitrapept around the opposite principle. Each batch is independently tested and its certificate of analysis travels with the product, on the page and on the vial.
That’s it. Clean compounds, honest testing, and results you can check yourself before you ever open a vial.
How it’s made
From synthesis to your bench
Four controlled steps stand between a raw sequence and the vial that reaches you — each one documented, and the last one published.
Contact usEU synthesis
Produced by verified research manufacturers using solid and solution-phase synthesis under strict QC.
In-house QC
Every batch checked for purity and stability before it leaves production.
Third-party testing
Independent HPLC, mass spec, heavy metals and endotoxin testing by Janoshik.
COA & dispatch
The certificate is published and linked to the vial, then shipped within 24 hours.
What we stand for —
Our principles
Verified, not claimed
Independent testing on every batch, with the report attached. No purity promises without evidence.
Quality obsessed
Verified manufacturing partners and strict quality control from the first step to the sealed vial.
Straight with you
