Verified Potency

HPLC Confirmed

Every vial is tested via HPLC to confirm it contains exactly what the label says—down to the microgram. No approximations.

Why it matters: Peptide potency directly determines research outcomes. Underdosed vials waste time and corrupt data.

Got Questions

Frequently asked questions

Everything you need to know about our peptides, quality standards, and ordering process.

What purity level are your peptides and how is it verified?

All Eon Peptides are manufactured to ≥99% purity, verified through independent HPLC analysis conducted by accredited U.S. laboratories. Each batch undergoes identity confirmation via mass spectrometry. Full analytical data is published on every product page.

What is a Certificate of Analysis (CoA) and how do I read it?

A CoA is a document from an independent laboratory confirming the identity, purity, and composition of a peptide batch. Key values: HPLC purity ≥99%, molecular weight confirmation via mass spec, and lot number traceability. Every Eon Peptides order includes a free CoA.

How do I reconstitute lyophilized peptides?

Slowly add bacteriostatic water along the vial wall to avoid disrupting the peptide cake. Gently swirl — do not shake — until fully dissolved. Volume of solvent determines concentration. Always reconstitute under sterile lab conditions.

How should I store peptides before and after reconstitution?

Unreconstituted: store at -20°C long-term or 2–8°C short-term, sealed and away from light. Once reconstituted with bacteriostatic water, refrigerate at 2–8°C — typically stable for 3–4 weeks. Avoid repeated freeze-thaw cycles.

How fast do you ship and do orders include cold packs?

Orders placed before 2PM EST ship same day with cold packs included. Standard delivery is 2–5 business days within the continental US. Expedited options available at checkout. All orders include free shipment protection.

Are these peptides for human use?

No. All products are strictly for laboratory research and analytical purposes only. They are not intended for human or veterinary use, and are not approved for any therapeutic, diagnostic, or medical application.

What the Research Community Says

Verified feedback from laboratories, academic institutions, and research organizations.

R1 Research University Principal Investigator, Molecular Biology
★★★★★

“We’ve tested peptides from several vendors over the years. Eon’s lot-to-lot consistency is exceptional. Our HPLC results match their COAs within margin every time. That reliability matters when you’re publishing.”

Biotech Startup, Boston Director of Research
★★★★★

“Fast shipping was critical for our timeline. Ordered Monday afternoon, had compounds on the bench Wednesday morning. Packaging was professional and temperature-controlled. Exactly what a serious operation needs.”

Independent Research Laboratory Laboratory Director
★★★★★

“The COA documentation is thorough: mass spec, HPLC purity, endotoxin testing. We ran independent verification on our first order and everything checked out. Now they’re our primary vendor.”

Contract Research Organization Preclinical Research Manager
★★★★★

“We require stringent documentation for our pharma clients. Eon provides batch-specific COAs with full analytical data. No chasing vendors for paperwork. Their support team actually understands research timelines.”

State University Medical Center Research Associate, Pharmacology
★★★★★

“Switched from our previous vendor after purity issues derailed a six-month study. Haven’t looked back. Eon’s compounds perform exactly as expected. No surprises, no wasted experiments.”

Private Research Institute, CA Senior Scientist, Regenerative Medicine
★★★★★

“Price-to-quality ratio is the best we’ve found. Comparable purity to premium vendors at a fraction of the cost. For grant-funded research, that efficiency matters. The bundle discounts help stretch limited budgets further.”
