Laboratory Standards
Purity You Can Verify
Every peptide we ship is independently analyzed by a third-party laboratory and arrives with the lot's certificate of analysis. You see the same data we do — compound identity, mass-spec confirmation, and HPLC purity — before the vial reaches you.
- UPLC-MS verification — identity and purity confirmed on each lot
- Mass-spec identity match — observed m/z compared to theoretical molecular weight
- Synthesis partners operate under ISO-certified cleanroom conditions
- Independent third-party analytical testing — COAs are data, not marketing
- Every order ships with its lot-specific certificate of analysis

1
Synthesis
Solid-phase synthesis by established partner laboratories using pharmaceutical-grade precursors and traceable raw materials.
2
Verification
Each lot is independently analyzed by UPLC-MS for compound identity and purity (≥99%) before it's released.
3
Cold-Chain Packaging
Lyophilized vials are sealed under inert atmosphere, boxed with cold packs as required, and shipped discreetly.
4
Delivered
Tracked shipping within 24–48 hours of order placement, with lot-specific COA included in every package.

Common Questions
Frequently Asked
Are your peptides research grade or pharmaceutical grade?
All HelixGen Labs products are sold strictly as reference-grade research compounds for in-vitro laboratory use. They are not pharmaceuticals, dietary supplements, or medical devices. Our internal purity and analytical standards meet or exceed pharmacopoeial references (≥99% HPLC-MS), but products are never intended for human or veterinary use.
How do I know the purity claims are real?
Every order includes a lot-specific certificate of analysis (COA) from an independent analytical laboratory. The COA identifies the compound, confirms it by mass spectrometry, and reports HPLC purity. Our most recent reference report is available directly from the homepage.
How are orders shipped, and how fast?
Orders placed before 2 PM EST typically ship the same business day, with a 24–48 hour standard dispatch window. Domestic US shipping is via tracked carrier in discreet, rigid packaging. Free shipping on orders over $150.
Do you ship internationally?
Yes — we ship to most countries that permit import of research compounds. International customers are responsible for ensuring local regulatory compliance before ordering.
What's your return and satisfaction policy?
If a product fails to meet the stated COA specification, we'll replace or refund the full purchase — no questions, no restocking fees. Because these are sealed laboratory reagents, we cannot accept returns of opened vials for reasons other than a verified quality defect.
How should I store the peptides I receive?
Store lyophilized peptide at –20°C for long-term storage (up to 24 months). Once reconstituted with bacteriostatic water or sterile saline, store at 2–8°C and use within 30 days. Avoid repeated freeze–thaw cycles, and always handle under sterile conditions.
