Laboratory Standards
Purity You Can Verify
Every peptide we ship goes through a rigorous multi-step verification program before release. We don't ship a single vial until we can prove exactly what's inside it.
- HPLC-MS verification β identity and purity confirmed on each lot
- Endotoxin & bioburden screening β per USP <85> and <61> guidance
- Synthesis partners operate under ISO-certified cleanroom conditions
- Independent third-party analytical testing β COAs are data, not marketing
- Every order ships with its lot-specific certificate of analysis

Our Process
From Lab Bench to Your Doorstep
A straightforward, transparent workflow engineered for researchers who value reliability.
1
Synthesis
Solid-phase synthesis by established partner laboratories using pharmaceutical-grade precursors and traceable raw materials.
2
Verification
Each lot is independently tested by HPLC-MS for identity, purity (β₯99%), and endotoxin load 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 24β48 hours of order placement, with lot-specific COA included in every package.
Why Researchers Choose Us
Four Reasons Labs Keep Coming Back
Verifiable Purity. Every lot ships with a COA from an independent third-party lab β identity, HPLC-MS purity, and endotoxin load, all on one document. Retention samples held two years for independent re-test.
Full Traceability. Lot-specific batch records from synthesis to shipment. Ask for the raw HPLC trace on any lot you've received and we'll send it within a business day.
Fast Dispatch. Orders before 2 PM EST ship same business day via tracked carrier. Temperature-sensitive compounds include medical-grade cold packs. Free US shipping over $150.
Spec Guarantee. If a product doesn't meet its stated COA spec, we replace or refund in full β no restocking fees, no questions.
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 (β₯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) generated by an independent third-party analytical laboratory. The COA identifies the compound, reports HPLC-MS purity, and lists endotoxin screening results. We retain a sealed retention sample from every lot for two years β if you ever want an independent re-test, just ask.
How are orders shipped, and how fast?
Orders placed before 2 PM EST typically ship the same business day, with a 24β48 hour standard dispatch window. Domestic US shipping is via tracked carrier in discreet, rigid packaging. Temperature-sensitive compounds ship with medical-grade cold packs. Free shipping on orders over $150.
Do you ship internationally?
Yes β we ship to most countries that permit import of research compounds. International customers are responsible for ensuring local regulatory compliance before ordering. Contact our team for specific country availability.
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 β 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 β20Β°C for long-term storage (up to 24 months). Once reconstituted with bacteriostatic water or sterile saline, store at 2β8Β°C and use within 30 days. Avoid repeated freezeβthaw cycles, and always handle under sterile conditions.
