What We Do

End-to-end contract manufacturing under controlled, documented conditions - from raw material to a finished, filled, and sealed product. All done in the USA.

Encapsulation

Two-piece capsule filling for powders, granules, and blends. Capsule size, fill weight, and blend uniformity matched to your formula and verified in process.

Liquid Filling

Filling and sealing for serums, oils, tinctures, and liquid supplements. Fill volumes checked throughout the run and finished to your spec.

Custom Formulation

We develop and refine formulas to your specification, from raw material selection through a stable, reproducible finished product - domestically, from our California facility.

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 formulation, filling, 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 filling 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 ingredient identity and confirm purity levels.

Third-Party Testing

Independent analytical verification through third-party laboratories - including microbial 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.
