Research peptides you can actually verify.

Vitrapept exists for one reason: to make high-purity research compounds you can trust, with the proof attached to every order.

Who we are

Purity first, proof always

Explore catalogue

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 us

EU 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.
