THE PURAXIS STANDARD

Every batch earns
its purity claim.

Most peptide brands publish a single generic COA and call it good. We test every batch individually using RP-HPLC and mass-spectrometry confirmation, then publish the results at a public URL. Scan the QR on your bottle and read your batch results yourself.

Reversed-Phase HPLC

Separates peptide from impurities with chromatographic precision.

Mass-Spec Confirmation

Confirms molecular identity — not just purity percentage.

Sequence Verification

Amino acid sequence confirmed against reference standard.

ACTIVE INGREDIENTS

The peptide families
that actually work

Signal Peptides

Matrixyl (Pal-KTTKS)

Mimic collagen breakdown fragments, triggering the skin's natural repair response to synthesize new collagen I, III, and IV.

20+ RCTs
Neurotransmitter-Inhibiting

Argireline (Ac-EEMQRR-NH₂)

Block SNARE complex assembly, reducing acetylcholine-mediated muscle contraction and softening expression lines over time.

12+ clinical studies
Carrier Peptides

GHK-Cu (Gly-His-Lys·Cu²⁺)

Deliver copper ions directly to fibroblasts, stimulating collagen synthesis, antioxidant gene expression, and wound healing cascades.

30+ peer-reviewed papers
