PE 22-28

Spadin analog peptide studied for mood regulation and TREK-1 channel modulation. This compound represents one of the most requested tools in its category, selected by scientific teams that refuse to compromise on purity, identity, or traceability.

PE 22-28 is the choice of advanced laboratories who require a pharmaceutical-grade, lot-traceable compound backed by complete analytical documentation. Every vial originates from GMP-aligned manufacturing partners, passes multiple quality control checkpoints before leaving the production floor, and ships with its corresponding Certificate of Analysis. Batch-to-batch consistency is a cornerstone of the BioPeptideX program — your experimental results should never depend on which supplier you chose this month.

BioPeptideX delivers PE 22-28 in lyophilized form for maximum stability, with purity ≥99% verified by reverse-phase HPLC and identity confirmed by mass spectrometry. Cold-chain integrity is maintained from origin to your laboratory, and every vial carries a printed lot number that cross-references directly to its COA. No ambiguous labels. No substitutions. No surprises.

Laboratories at universities, private laboratories, and clinical centers across Peru and Latin America choose BioPeptideX precisely because of this level of transparency. PE 22-28 is held in stock under pharmaceutical-grade conditions and ships with thermal packaging where appropriate, ensuring the compound arrives at your bench in the exact condition it left our facility.
