Research Peptides Tested to ≥99% Purity,
With a COA on Every Batch

No. PrimeTime BioLabs supplies every product strictly for laboratory and in-vitro research by qualified professionals. These compounds are not drugs, dietary supplements or cosmetics. They are not intended for human or animal consumption, and they are not for diagnostic or therapeutic use of any kind.

A Certificate of Analysis is a batch-specific document recording a compound's measured purity, confirmed identity and physical characteristics. Ours lists the HPLC purity percentage and chromatogram, the mass spectrometry result, the batch number, the testing laboratory and the analysis date. Every order includes the COA for its batch.

Find the batch number printed on your vial label and on the packing documentation. Enter it on our Certificates of Analysis page to retrieve the original document. Because we archive every COA we issue, the record remains available after purchase for method reporting and audit purposes.

We synthesise our research peptides in United States laboratories using solid-phase peptide synthesis. Manufacturing, purification and release testing all run under US-based process controls. Consequently, batch records and analyst traceability stay within a single regulatory jurisdiction.

Peptides ship as lyophilised powder in sealed vials, packed in insulated containers with coolant and moved on expedited services. On arrival, store unopened vials at −20°C for long-term stability. Lyophilised material tolerates short periods at ambient temperature during transit without loss of integrity.

Sealed at −20°C, away from light and moisture, lyophilised research peptides generally remain stable for 24 months or longer. Once reconstituted, stability drops considerably and depends on the specific sequence, the solvent used and the storage temperature. Always confirm against your own stability data.

Yes. We accept custom synthesis requests for specialised research work. Send your target sequence, required purity threshold and quantity, plus any modifications such as amidation, acetylation or conjugation. Our team will then return a quotation with a projected timeline.

Yes. We supply university laboratories, contract research organisations and private research groups. Our contact team supplies purchase orders, W-9 forms, batch documentation and COA archives on request. That covers most institutional procurement requirements.

Manufacturers produce and test research-grade peptides for laboratory use, then document purity and identity on a Certificate of Analysis. Pharmaceutical-grade material follows GMP for clinical use and carries regulatory approval. The two are never interchangeable, and research-grade compounds must never be used in humans.

Yes. Volume pricing is available for repeat research accounts and larger orders. Contact our team with the compounds, quantities and cadence you expect, and we will return a schedule. Peptide bundles are also listed in the catalogue for comparator and dose-range study designs.

Because these are temperature-sensitive research reagents, we handle returns case by case under our published refund policy. Contact us within the stated window if a batch arrives damaged, or if the material does not match its Certificate of Analysis. We will then replace or refund it.
