American-Made Peptide Manufacturing Built on Precision, Purity, and Process
Decades of hands-on experience in peptide synthesis and compounding — right here in California. GMP-aligned processes, ISO-rated equipment, and third-party verified quality built for partners who demand domestic consistency they can count on.
What We Do
End-to-end peptide synthesis and compounding under controlled, documented conditions — from raw material to finished lyophilized product. All done in the USA.
Custom Peptide Synthesis
We synthesize peptides to your specifications using pharmacist-formulated production protocols under controlled laboratory conditions — domestically, from our California facility.
Lyophilization & Finishing
Lyophilized products prepared and sealed to USP standards for stability and shelf life. Every batch handled with precision.
Sterile Filtration
All injectable-grade preparations undergo 0.22 micron sterile filtration to meet purity and safety requirements.
Batch Documentation
Full batch records, SOPs, COAs, and SDS/MSDS documentation provided with every order. Transparency at every step.
Why Work With MolecularLab
We've built our lab around one standard: doing it right. That means rigorous process controls, verified quality, and the experience to back it up — all from American soil.
Made in America — California-Based
Our laboratory is proudly based in California. All synthesis, compounding, and testing happens domestically — no overseas production, no international supply chain uncertainty.
GMP-Aligned Manufacturing
Our production processes follow GMP-aligned standards, ensuring consistency, traceability, and compliance from batch to batch.
ISO-Rated Equipment
Every synthesis and testing step is conducted on ISO-rated instrumentation, maintained and calibrated to specification.
HPLC Identity & Purity Verification
We use high-performance liquid chromatography (HPLC) on every batch to verify peptide identity and confirm purity levels.
Third-Party Testing
Independent analytical verification through third-party laboratories — including endotoxin testing and heavy metals screening — on a per-batch basis.
Full Chain of Custody Documentation
From qualified supplier sourcing with COAs and SDS on all raw materials to finished product release documentation, every step is accounted for.

Wholesalers who need a reliable U.S.-based synthesis partner to supply consistent, documented peptide inventory at scale.
Compounding Pharmacies
Licensed compounding facilities that require consistent, high-purity peptide APIs manufactured under controlled domestic conditions.
Research Institutions
Academic and private research labs that need custom peptide synthesis with full analytical documentation.
Pharmaceutical Companies
Organizations requiring contract peptide manufacturing with GMP-aligned processes and verified batch records.
Biotech & Life Science Firms
Biotech partners developing peptide-based therapeutics or research compounds who need a reliable American synthesis partner.
Built in California. Trusted Across the Country.
MolecularLab was founded by practitioners with years of direct experience in peptide synthesis and pharmaceutical compounding — operating out of California, USA. Our facility operates under strict quality controls — not because it's required, but because it's the only way we know how to work.
Every peptide we produce is tested, documented, and traceable. We do not cut corners on process, sourcing, or verification. Our clients trust us because we've earned it, batch by batch.
