A research-focused catalog supported by ISO 17025 third-party testing, 99%+ HPLC purity and per-batch documentation — built for the people doing the work.
Purity, verified by HPLC.
Every batch is assessed by an accredited (ISO 17025) independent laboratory and confirmed by high-performance liquid chromatography. If a batch does not meet the threshold, it is not released — no exceptions, no guesswork.
Explore the catalog by research area. Each field groups the compounds studied within it — organized for research, not merchandising.

Explore →Every material moves through the same four-stage sequence — from preparation, through independent verification and documentation, to the moment it ships. Nothing skips a step.
Materials are lyophilized and handled in a controlled US facility, then sealed for research use.
Each batch is assessed by an accredited, independent third-party laboratory.
A certificate of analysis is generated and tied to the exact production lot.
Orders are processed same-day and dispatched with care from the USA.
Every batch should be supported by meaningful analytical information. These are the assessments — and what each one confirms — behind the materials in the Helio catalog.
Most suppliers ask you to take their word for it. Helio is built the other way around — every claim below is something you can check.
Independent, accredited laboratory testing — not in-house self-certification.
A certificate of analysis tied to the exact lot you receive, not a representative sample.
Manufactured domestically, processed same-day, shipped discreetly to all 50 states.
Documentation is organized around the batch. Locate the lot on your material, and the analytical record that belongs to it follows.
Read the lot printed on the material you received.
Match it to the identity and purity results for that lot.
Access the certificate of analysis for the batch.
Keep the record alongside your own research notes.
Practical guidance for working with lyophilized research materials — from arrival to bench.
How to reconstitute lyophilized material with bacteriostatic water, and how to calculate concentration for your work.

All Helio materials are supplied strictly for laboratory and analytical research. They are not drugs, supplements or foods, and are not intended for human or veterinary consumption, diagnosis, treatment or prevention of any disease. At checkout you’ll be asked to confirm your research organization type.
Every batch is HPLC-verified to exceed 99% purity and confirmed for identity by mass spectrometry, through an accredited (ISO 17025) independent third-party laboratory. If a batch doesn’t meet the threshold, it isn’t released.
Yes. Each production batch is documented with a certificate of analysis tied to its exact lot, recording identity, purity and the methods used. You can browse certificates on our Quality page.
Keep material cold and away from light on arrival. Lyophilized powder is stable short-term at 4°C (39°F); for long-term storage, freeze at −20°C or below. Reconstitute with bacteriostatic water for laboratory use.
We ship to all 50 US states via USPS and UPS. Orders are processed Monday–Friday (8:00am–4:30pm EST cut-off) and Saturday mornings, with same-day dispatch on in-window orders. We don’t ship Sundays or national holidays.
We offer a 15-day return policy. Items must be unopened, unused and in original packaging with proof of purchase. To start a return, contact info@heliopeptides.com; approved refunds are issued to the original payment method within 10 business days. Sale items and gift cards are non-returnable.
