01 — Capabilities
One partner, the full chain from sequence to shipment.
We operate as the production layer behind your brand. You set the spec; we synthesize, purify, fill, and finish under one roof.
Synthesis Lab
/ 01
Custom Synthesis
Any sequence, any scale. Send the sequence and target quantity and we synthesize to order — from milligram research lots to bulk production runs.
- Solid-phase synthesis in a domestic facility
- Single peptides and multi-peptide blends
Vial Filling & Lyophilization
/ 02
Fill & Finish
Precision vialing and lyophilization to your fill weights. Consistent reconstitution, clean stoppering, and tamper-evident sealing — lot to lot.
- Lyophilized to spec for stability and shelf life
- Repeatable fill weights across runs
Packaged Finished Units

02 — Our Facility
Domestic production, one controlled environment.
Our APIs are sourced from vetted pharmaceutical partners — then everything downstream happens under one roof in the United States: analytical verification, fill, finish, labeling, and fulfillment. Controlled, documented, and fully traceable.
That control is what lets us stand behind every lot with documentation, and what lets your brand promise consistency to its own customers.
03 — About Us
Transparency isn't a feature. It's the whole business.
A finished vial is only as good as the molecule it starts with. We treat API sourcing as the most important decision we make — and we're open about exactly where ours comes from and why.
Our peptide APIs (Active Pharmaceutical Ingredients) are produced by a publicly listed pharmaceutical manufacturer based in Guangzhou with more than twenty years in peptide research, development, and large-scale production. Operating since 1995, it is recognized as one of the early pioneers of peptide pharmaceuticals within its sector.
As a pharmaceutical-industry producer, our partner maintains rigorous quality systems, advanced analytical testing capabilities, and tightly controlled production environments. That depth of expertise in peptide synthesis and purification yields exceptionally high-purity APIs with outstanding batch-to-batch consistency.
Every batch undergoes comprehensive analytical testing and is backed by a Certificate of Analysis verifying identity, purity, and quality specifications — complete traceability and confidence on every production run.
We selected this partner for its pharmaceutical expertise, publicly listed corporate governance standards, advanced manufacturing infrastructure, and proven track record across the global peptide industry. Sourcing premium, pharmaceutical-grade APIs is what lets us deliver products built on quality, purity, consistency, and reliability.
How we vet a source
We don't take a supplier's word for it. Neither should you.
- Pharmaceutical-grade APIs only — no commodity research-chemical sourcing.
- Publicly listed governance — accountable, audited corporate standards.
- Advanced analytical testing — HPLC and mass spectrometry on every batch.
- COA per batch — identity, purity, and specification documented.
- Proven track record across decades in the global peptide industry.

04 — Process
A controlled path, documented at every step.
01
Spec & Sequence
You submit the sequence, fill weight, and volume. We confirm feasibility, lead time, and pricing.
02
Synthesis
Solid-phase synthesis to order in our domestic facility, scaled to your run size.
03
Purification
Multiple rounds of preparative HPLC strip reagents and byproducts to >99% purity.
04
Verification
Mass spectrometry confirms each peptide against its theoretical molecular weight. COA issued per lot.
05
Fill & Lyophilize
Precision filled, frozen, and lyophilized to your specification for stability and shelf life.
06
Label & Ship
Your branding applied, units packed, and shipped same-day-capable from the USA.
05 — Quality
Trust is analytical, not aspirational.
Every lot is treated as evidence. Nothing leaves the facility without documentation a researcher can rely on.
Purity >99% by HPLC
Liquid chromatography isolates the target peptide and removes contaminating reagents and byproducts.
Identity confirmed by MS
Mass spectrometry verifies the theoretical molecular weight of every peptide before release.
Certificate of analysis per lot
Documented purity and identity data shipped with every production run, traceable by lot number.
Consistent, repeatable lots
Standardized process controls keep fill weights and purity stable run to run.
Built for partners
Wholesale-only. Volume pricing, real terms, named account management.
- Minimum order quantities structured for resale, not retail.
- Tiered volume pricing that scales as your order size grows.
- Account approval — verified business entities only.
- Dedicated point of contact from quote through delivery.
Evaluate before you scale
Sample orders for third-party testing.
Verify our purity for yourself. We offer smaller sample-quantity orders so labs and brands can run independent third-party analysis before committing to a bulk run. Every sample ships with its certificate of analysis and lot number.
What ships with every sample
- Per-lot certificate of analysis — purity and identity data, traceable.
- Lot number matched to your eventual production run.
- Ships to your testing facility of choice for independent analysis.
- Sample pricing credited toward your first bulk order on approval.
