THE COMPANY

Advanced Sequence is a research supply company.

Advanced Sequence supplies documented, third-party tested peptides to qualified researchers. Every product is sold for laboratory research use only, with no human-use claims, no protocols, and no implied applications.

WHY WE EXIST

Documentation is the product.

The research-peptide market has a documentation problem. Purity figures are quoted without a method behind them, batch numbers are missing or recycled, and certificates of analysis are either absent or impossible to verify. A researcher ordering a reference material has no reliable way to know what is actually in the vial.

Advanced Sequence was built around a single rule: every vial ships with a batch-specific certificate of analysis from an independent, US-based laboratory. Each certificate discloses the testing method, the laboratory that ran it, and the exact batch it belongs to. Identity is confirmed by mass spectrometry and purity by reverse-phase HPLC before a batch is released.

We do not publish protocols, dosages, or applications, and we make no claims about what any compound does in a living system. Our role stops at supplying a well-characterised material and the paperwork that describes it. What the research is for belongs to the researcher.

FOUNDER NOTE

Advanced Sequence was founded in 2026 by Jack O'Leary. For more than a decade he built Inca Trail Terpenes in Los Angeles and wrote The Terpene Book, a molecular-level reference on how organic compounds interact with human physiology. He thinks in sequences, and that same way of looking at molecules is what carried him from terpenes into peptides.

WHAT WE DEMAND OF EVERY BATCH

A purity number without a method is decoration, not documentation.

01
Third-party tested

Every batch is analysed by an independent US laboratory, never in-house alone.

02
Method disclosed

Each certificate states the testing method and the lab that ran it, not just a number.

03
Batch traceable

Vials carry a lot number that maps to one specific certificate of analysis.

04
Research use only

No human-use claims, no protocols, no dosages, no implied applications. No exceptions.

SOURCING & TESTING

How a batch reaches the catalog

Every lot passes the same sequence before it is listed. Nothing ships on a supplier's word alone.

STEP 1
Vet the manufacturer

We source only from US synthesis facilities that can supply per-batch HPLC purity and mass-spectrometry identity data on request.

STEP 2
Independent testing

A sample from each incoming lot is sent to a third-party laboratory for reverse-phase HPLC purity and mass-spectrometry identity confirmation.

STEP 3
Verify and document

We match the certificate to the physical lot, confirm the batch number, and publish the certificate before the batch is listed.

STEP 4
Cold-chain dispatch

Lyophilized vials ship domestically with the batch certificate included, packed to keep the material stable in transit.

See the documentation for yourself.

Every batch we list carries a published certificate of analysis. Read them before you order.
