Peptides That Show Their Work.
Popular research peptides
Start With the Proven Few.
Purity
HPLC — published to the tenth.
Identity
The vial is what the label says.
Endotoxin
LAL-tested on every lot.
On the Record
Every result published with its lot.
The Standard Behind Every Lot.
Lot-Tested, Not Self-Graded
Lyophilized, research-grade compounds — synthesized to specification and sealed for the bench.
Independent Verification
Tested by a third-party, A2LA-accredited laboratory — never in-house.
Molecular Integrity
HPLC purity to the tenth, plus assay and endotoxin — the three results that decide pass or fail.
Certified Analysis
A certificate of analysis for every lot, tied to its batch number and linked from the buy button.
Why Hello Stacks
The Certificate Is the Product.
Most vendors bury the COA. Some never publish one at all.
We put it inside the buy box:
- Batch number
- Tested purity
- Test date
- Lab name
Full certificate linked for every tested lot.
- Batch Passport on every product — real data, not a badge.
- Lab tests & COAs — every tested lot's certificate, downloadable.
- The blue check means one thing on this site: lab-confirmed.
Every field on the document is pulled straight from Vanguard's signed report — nothing on it is decorative.
- Issuing lab
- A named, ISO/IEC 17025-accredited third party — not us.
- Lot number
- Ties the vial in your hand to this exact tested run.
- Purity · Assay · Endotoxin
- The three results that decide pass or fail.
- Signatures
- A lab director and operations manager put their names on it.
MethodHPLC-UV/VIS · LAL (endotoxin) — per Vanguard Laboratory QMS
| Analysis | Method | Result | Status |
|---|---|---|---|
| Chromatographic purity | HPLC-UV/VIS | >99.80% + 0.18% | ✓Pass |
| Assay | HPLC-UV/VIS | 11.68 mg | ✓Pass |
| Endotoxins | LAL | <5.00 EU/mg* | ✓Pass |
*Pass/fail per the lab's own printed criterion: the USP/FDA threshold of 5 EU/kg — 350 EU total for a 70 kg adult.

FAQ
Questions, Answered.
The things researchers ask before their first order.
Because we don't do the testing — an independent, A2LA-accredited lab does. The certificate names the lab, the lot, the method (HPLC-UV/VIS), and the purity to the tenth of a percent. Open the signed COA on any product, before you buy.
Better than that — there's one for every lot. Each batch is tested on its own, so the COA ties the exact vial in your hand to the exact run it came from: batch number, test date, pass/fail.
Orders placed by 3:00 PM PST ship the same day in a plain, tracked box. You'll get a tracking number as soon as the label is created.
Compounds ship lyophilized (freeze-dried). Store the powder at −20°C and reconstitute with bacteriostatic water when ready. Each product page lists its specific handling note, and our reconstitution calculator does the math for you.
All products are sold strictly for in-vitro laboratory research and development use only. They are not drugs, foods, cosmetics, or dietary supplements, and are not intended to diagnose, treat, cure, or prevent any disease, nor for human or veterinary use.
