Purion is an ultra-high-purity cationic antimicrobial peptide that disrupts microbial membrane integrity through electrostatic interactions with phospholipid bilayers.
Purion is supplied as a lyophilized form at 10mg. For reconstitution, use bacteriostatic water (BAC water). Draw the appropriate volume of BAC water into a sterile syringe and inject it slowly along the wall of the vial. Do not shake — gently swirl until dissolved. Store reconstituted peptide at 2-8°C and use within 30 days.
Store lyophilized (unreconstituted) peptide at -20°C for long-term storage. Once reconstituted with bacteriostatic water, store at 2-8°C (refrigerated) and use within 30 days. Avoid repeated freeze-thaw cycles. Keep away from direct light.
This product is intended for laboratory research use only and is not approved for human consumption. No clinical side effect profile is available. Researchers should review published literature for relevant preclinical data and follow all applicable safety protocols.

Letter from our science team
Hi,
We started this company because we saw how hard it was for independent researchers to access consistently high-quality peptide compounds. Too many suppliers cut corners on purity testing, skip the COA, or ship compounds in conditions that compromise stability.
We built our supply chain differently. Every compound we sell is manufactured under GMP-compliant conditions, independently tested by a third-party lab, and shipped via cold-chain logistics. No exceptions.
The science matters. The details matter. We take both seriously so researchers can focus on what they do best: advancing research.

Best cold-chain packaging I've seen
Everything arrived at the correct temperature with two ice packs still frozen after 3-day shipping. The vacuum-sealed vials were a nice touch.

Exceptional purity documentation
Full HPLC and mass spec data included with the COA. That level of documentation is exactly what IRB reviewers want to see. Makes our compliance paperwork much easier.

FAQ: Purion
Answers to common questions from researchers.
Purion is verified at 99.5% purity. Every batch is independently tested by a third-party laboratory and comes with a Certificate of Analysis (COA) documenting identity, purity, and peptide content.
Store lyophilized (unreconstituted) peptide at -20°C for long-term storage. Once reconstituted with bacteriostatic water, store at 2-8°C (refrigerated) and use within 30 days. Avoid repeated freeze-thaw cycles and keep away from direct light.
All orders ship within 24 hours of payment confirmation. Peptides are shipped with cold packs in insulated packaging to maintain stability during transit. Domestic orders typically arrive within 2-5 business days. You’ll receive a tracking number via email.
Use bacteriostatic water (BAC water) for reconstitution. Draw the appropriate volume into a sterile syringe and inject it slowly along the inside wall of the vial. Do not shake — gently swirl until the powder is fully dissolved. Store reconstituted solution at 2-8°C.
Yes. A third-party Certificate of Analysis (COA) is available for every batch. Contact our support team if you need a copy for your records.
