First Class Science
First Class Science is a trusted provider of high-purity research peptides, dedicated to supporting scientific and laboratory research with precision-manufactured compounds. Our peptides are produced using advanced synthesis methods and undergo rigorous third-party testing to ensure exceptional purity, consistency, and reliability. Committed to transparency and quality, First Class Science delivers research-grade peptide solutions designed to meet the highest industry standards.
Who we are
First Class Science manufactures every peptide we sell — we are not a reseller repackaging someone else’s batches. Using both solid-phase and solution-phase synthesis, combined with automated technology and expert manual technique, we produce compounds engineered to exceed 99% purity on every SKU. Each batch moves through multi-step quality control from synthesis to final packaging and is independently verified by HPLC and mass spectrometry before it ships. That is what a research-grade peptide is supposed to mean: a known, documented compound, not a guess.
why peptides?
Peptides let researchers isolate a single biological signal and study it directly, with a level of precision broader compounds can’t offer. That precision only holds up if the material itself is accurately characterized. Every peptide we manufacture ships with a batch-specific Certificate of Analysis and is verified by HPLC and mass spectrometry, so the compound in hand matches the documentation in the notebook.
buy more, save more
Ordering at scale for an ongoing study shouldn’t mean guesswork pricing. Volume discounts apply automatically at checkout — no code needed — so larger orders cost less per unit, without changing the batch-tested, COA-documented standard behind every SKU.
what’s next?
Every order ships cold-chain and same business day, with a batch-specific COA already on file in our COA Library. If a question comes up mid-study — a storage question, a documentation request, a batch lookup — our research support team responds within 24 hours, from people who know the chemistry.
