About HelixCore

Built on the boring stuff:
purity, paperwork, repeatability.

HelixCore Biotech is a U.S.-based research peptide supplier. We exist for one reason: most peptide vendors hide their assays behind “trust us” marketing. We don't. Every batch we ship has a third-party Certificate of Analysis published openly in our CoA library, readable by anyone, before they buy.

01

Independent labs, every batch

Identity, purity, and endotoxin content are confirmed by third-party reference labs — not our own bench. The assays we publish are the same assays you'd run if you were verifying us.

02

Boring release threshold: 98%

Anything below 98% gets destroyed, not discounted. Our long-run average across lot releases is >99%, and the released purity is printed on each CoA. By the time a vial leaves our facility it's already been verified — that's why every sale is final.

03

Same-day fulfillment from the U.S.

Orders placed before 2pm EST leave our facility the same business day in temperature-stable, discreet packaging. Most U.S. orders arrive in 2–3 days. No customs holdups, no overseas shipping windows.

04

For research use, period

Every product is sold strictly for laboratory and research purposes. We don't give dosing, administration, or therapeutic advice. Questions about a peptide's behavior in a research model are welcome; questions about human or animal use are not.

What we don't do

  • Make medical, therapeutic, or wellness claims about any product
  • Sell to anyone under 21 (or whatever the local minimum is for research-material purchase)
  • Ship blind — every order has a tracking number and shipment-protection coverage
  • Hide assays. If we don't have a current CoA, the product doesn't list.
  • Work with anyone misrepresenting RUO products in human-use contexts

Why “HelixCore”

The double helix is the most-recognizable symbol of biological research, and the core of our work is the same as anyone else doing real reference-material work: get the sequence right, prove the purity, document everything, ship it cold. We named the company after the discipline, not after a marketing focus group.

Compliance & the boring fine print

All HelixCore products are sold strictly for research, laboratory, and educational purposes. They are not approved by the FDA for human or veterinary use, and are not for in vivo administration. By purchasing, you confirm you are 21+ and using these materials in compliance with applicable law.
