Customer Reviews

Krzysztof — ★★★★★
Good product but slightly pricier per mg than the vial format. The convenience premium is worth it if you travel or prefer simplicity. If you're at home with no travel, vials are more economical. Quality is identical.
kim.d — ★★★★★
My husband uses the vial (he's comfortable with reconstitution). I use the pen (I'm not). Same results, same quality, different convenience level. The pen made NAD+ accessible for me.
Femke D. — ★★★★★
The pen format transformed my compliance. With vials I'd sometimes skip days because the reconstitution process felt like a chore after a long day. With the pen it takes 20 seconds. Haven't missed a dose in 3 months.
Piotr V. — ★★★★★
Support recommended the pen when I mentioned I was struggling with daily vial reconstitution. Best advice they gave me. Same excellent NAD+ quality, one-tenth the preparation time.
Eirik — ★★★★★
fourth pen. the mechanism hasn't degraded at all across dozens of uses. each dose is as smooth as the first. peptex engineering quality matches their peptide quality

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.
