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.
CERTIFICATE OF ANALYSIS — BATCH PX-MTX-240301
ACTIVE INGREDIENTS
The peptide families
that actually work
Matrixyl (Pal-KTTKS)
Mimic collagen breakdown fragments, triggering the skin's natural repair response to synthesize new collagen I, III, and IV.
20+ RCTsArgireline (Ac-EEMQRR-NH₂)
Block SNARE complex assembly, reducing acetylcholine-mediated muscle contraction and softening expression lines over time.
12+ clinical studiesGHK-Cu (Gly-His-Lys·Cu²⁺)
Deliver copper ions directly to fibroblasts, stimulating collagen synthesis, antioxidant gene expression, and wound healing cascades.
30+ peer-reviewed papersWHY PURAXIS
The brand that shows
its work
≥99% Purity
Our minimum purity threshold exceeds the 98% industry standard. Not a marketing claim — verified by RP-HPLC.
Batch-Level COAs
