LYOPHILIZED

Peptide Vials

VIEW ALL

Buy peptide vials supplied as lyophilized powder for reconstitution in your own protocol. The vial catalog spans incretin peptides, BPC-157 and the BPC-157 + TB-500 blend, growth-hormone secretagogues, and specialized research compounds. Most vials are manufactured to exceed 99% chromatographic purity, verified by independent HPLC and LC-MS analysis. For laboratory research use only — see the reconstitution calculator before planning a dilution.

HPLC TESTED

Peptide Capsules

Where to Buy Peptides Online: What to Look For

Frontier Peptide Labs supplies research-grade peptides to laboratories, universities, and independent researchers who need dependable, well-documented compounds for in vitro and in vivo study. Every product in the catalog — from lyophilized peptide vials to peptide capsules and liquid peptide sprays — is manufactured and packaged strictly for laboratory research use, and every listing is built around the same standard: identity, purity, and batch-to-batch consistency that can be verified through independent testing, not simply claimed on a label.

Testing sits at the center of that standard. Each batch is analyzed by an independent, ISO 17025-accredited laboratory using high-performance liquid chromatography (HPLC) and liquid chromatography–mass spectrometry (LC-MS), the two analytical methods researchers rely on to confirm compound identity and quantify purity. Most vials in the catalog are manufactured to exceed 99% purity, and a Certificate of Analysis (COA) documenting those results is available for every batch, giving research teams a paper trail they can reference in their own protocols. This is also why the site’s research guides go into detail on reading a COA, interpreting HPLC output, and distinguishing purity claims for raw peptide powders from the assay and content testing used for finished capsule and spray formulations.

Catalog breadth is the other half of the equation. The Vials category spans dozens of research compounds across several active areas of study: GIP/GLP-1/GCGR incretin-receptor peptides such as Semaglutide, Tirzepatide, and Retatrutide; peptides studied in tissue-repair research, including BPC-157 and the combined BPC-157 + TB-500 blend; growth-hormone secretagogues such as Sermorelin, Ipamorelin, CJC-1295, and Tesamorelin; and specialized research compounds — GHK-Cu, Epithalon, Thymosin Alpha-1, MOTS-c, Kisspeptin-10, PT-141, IGF-1 LR3, KPV, and Selank among them — all supplied as lyophilized powder for reconstitution. Beyond vials, the catalog extends to peptide capsules — including TB-500 and BPC-157 capsule formats — for researchers who need a shelf-stable format, and liquid peptide sprays for protocols that call for a pre-formulated solution. Supporting products, including bacteriostatic water and multi-peptide research sets, round out what a laboratory needs to run a study without sourcing components from multiple suppliers.

None of this replaces peer-reviewed literature. The site’s research library summarizes published preclinical findings for each compound with full citations, and the guides section covers the practical side of laboratory work — cold-chain handling, reconstitution math, solvent selection, and storage stability — so a protocol can be planned before a vial ever arrives. Every product, resource, and article carries the same reminder: these are laboratory research compounds intended exclusively for qualified research and development use, not for human or veterinary consumption, diagnostic use, or any therapeutic application. Frontier Peptide Labs exists to give the research community consistent, well-tested materials and the documentation to back them up.

Frequently Asked Questions

Every batch is tested by an independent third-party laboratory before it ships, and the results are published as a batch-specific Certificate of Analysis at COAs & Lab Reports. Match the batch number on your vial to the COA to confirm identity and purity for that exact lot. If you’re new to reading one, our guide walks through what each section of a COA means.

Each batch is analyzed by an independent third-party laboratory using HPLC and LC-MS to confirm identity and quantify purity. Most vials in the catalog are manufactured to exceed 99% chromatographic purity. Results are published in a Certificate of Analysis available for each batch, so you can verify a compound before it enters a study.

Vials contain lyophilized peptide powder that you reconstitute with an appropriate diluent in your own protocol. Capsules and liquid sprays arrive pre-formulated and shelf-stable, with no reconstitution step. Testing differs by format: raw powders are reported as chromatographic purity, while finished capsules and sprays are reported by assay and content testing. All three are supplied strictly for laboratory research.

Reconstitution means dissolving lyophilized powder in a suitable diluent to reach a known working concentration. The correct volume depends on the peptide mass in the vial and the concentration your protocol calls for. Our peptide reconstitution calculator does the arithmetic; this guide covers diluent selection, and this one works through a full example.

It depends on the state of the compound. Lyophilized peptides tolerate ambient shipping but should be moved to cold storage on arrival — typically −20 °C or below for long-term stability. Once reconstituted, peptides generally require refrigeration and have a much shorter usable window. See cold-chain receiving and storage and stability of GLP-1 peptides in the laboratory.

They answer two different questions. HPLC separates the sample and reports the proportion of UV-absorbing material corresponding to the target peptide — the purity percentage on your COA. This is a chromatographic figure: it does not account for water, residual solvent or counterion, so net peptide content by mass is a separate measurement. LC-MS measures molecular mass, confirming the material matches the expected peptide. Reading both together is what tells you a compound is the right molecule at the stated purity.
