Customer Reviews

Malgorzata — ★★★★★
My doctor was surprised I was using an injectable for weight management (she expected oral medication). When I showed her the pen format she said it looked more professional and controlled than she expected. Peptex quality speaks for itself.
linn.s — ★★★★★
Recommended the pen to three friends who were interested in tirzepatide but intimidated by vials. All three are now ordering regularly. The pen format lowered the entry barrier dramatically. Quality is peptex standard (excellent).
Ragnar — ★★★★★
The pen format makes titration simpler for beginners. The dial shows exactly how much you're injecting. No concentration calculations, no unit conversions. Peptex engineered this well.
andrea_fit — ★★★★★
The pen format eliminated every barrier I had with tirzepatide. No reconstitution, no dose calculations, no syringe technique to learn. Dial the dose, inject, done. Lost 8kg in three months. Peptex pen quality is excellent.

travel with the tirzepatide pen monthly. flies through airport security without questions (looks like an insulin pen). keeps cold in my travel cooler for 8+ hours. peptex made my weight loss protocol completely portable

Quality Certificates

Third-party laboratory Certificates of Analysis (COA) for every PEPTEX peptide

Why transparency matters

Research-grade peptides require verified identity and purity. An unverified vial is an unverified experiment.

Each order ships with a physical COA and batch-specific QR code.

Testing methodology

HPLC (purity + impurities), mass spectrometry (molecular mass confirmation), appearance check, and moisture content. Reports issued by EU-based accredited laboratories.

Every batch of PEPTEX peptides is tested by an independent accredited laboratory. All batches meet or exceed ≥99% purity — no exceptions.

Frequently asked questions

What does ≥99% purity mean?

It means that at least 99% of the powder is the target peptide.

How is the batch linked to the COA?

Every vial carries a batch number matching the COA.

Can I verify the COA independently?

Yes — each COA carries the issuing laboratory name and report ID.
