USA-Manufactured · Research Use Only
BioSequence Labs — research peptides, verified by sequence.
Single compounds, combination blends, and custom formulations synthesized in U.S. GMP-compliant facilities and confirmed by independent HPLC and mass-spectrometry testing — with a lot-specific Certificate of Analysis on every order.
Third-party tested
Independent HPLC & MS on every lot — not self-reported.
Made in the USA
Synthesized in domestic GMP-compliant facilities.
COA per lot
Lot-specific Certificate of Analysis with every shipment.
Fast, discreet shipping
Free same-day dispatch on orders over $150.
Inside the lab
Verified by instruments, not adjectives.
Every compound we ship is characterised on the same analytical stack researchers trust — HPLC for purity, mass spectrometry for identity — before it ever reaches your bench.
The BioSequence Process
From sequence to shipment — four controlled steps.
Sourced
Compounds selected against defined research-grade specifications.
Synthesized
Produced in U.S. GMP-compliant facilities with lot tracking.
Verified
Independent HPLC and mass spectrometry confirm purity and identity.
Documented
A lot-specific Certificate of Analysis ships with every order.

You don't have to take our word for it.
- Independent, accredited third-party laboratories — not in-house numbers.
- HPLC quantifies purity; mass spectrometry confirms molecular identity.
- Every lot carries its own Certificate of Analysis, tied to your order.
- Pure active compound only — no bulking agents or fillers.

Common questions
What researchers ask most.
Are these products legal to purchase?
Our products are sold strictly as research chemicals for in-vitro laboratory research and development. They are not approved by the FDA for human or animal use, are not for consumption, and it is the buyer's responsibility to comply with all applicable laws in their jurisdiction.
How is purity verified?
Every lot is tested by independent third-party laboratories using HPLC to quantify purity and mass spectrometry to confirm molecular identity. A lot-specific Certificate of Analysis is provided with your order.
How are orders shipped and stored?
Orders over $150 ship free with same-day dispatch on business days. Store lyophilized peptides as described in the product documentation to preserve stability.
Do I need an account to order?
Yes. Purchasing requires a verified account and confirmation that you understand these products are for research use only. This supports responsible handling and order verification.
What is your return policy?
Because these are sensitive research materials, returns are limited to documented issues with the product as shipped. See our Returns policy for full details.
