Shop Peptides

Our catalog spans more than forty research peptides organized into six functional categories — recovery, skin and tissue, strength and growth-hormone secretagogues, longevity, sleep and neurological, and immune. Each category page includes a deep-dive on the compounds, their mechanisms of action, and links to published preclinical literature so you can evaluate the science before you order.

Every peptide we list is independently tested. Purity is verified by reverse-phase HPLC and confirmed by mass spectrometry, with the resulting Certificate of Analysis available on request for the exact lot you receive. We publish the testing methodology, acceptance thresholds, and what each line of a COA actually means on our quality page — and our guide to reading a COA walks through the same document field by field.

What to expect when you order

• Lyophilized vials shipped cold-packed when ambient temperatures require it, with handling guidance included so reconstitution and storage stay within published stability windows.
• Same-day shipping on orders placed before 2:00 PM EST, with a flat $10 shipping fee and a 6% processing fee disclosed upfront in the cart — no surprises at checkout.
• Discreet packaging and tracked dispatch from our US-based facility, with delivery confirmation emailed automatically.

Built for serious researchers

CALM is a research-supply company. The compounds listed here are sold strictly for in-vitro and laboratory research and are not intended for human consumption, diagnosis, treatment, or cure of any condition. If you're new to research peptides, start with our pillar guide "What are peptides?", then explore the Learn library for compound-specific overviews on BPC-157, GHK-Cu, NAD+, TB-500, CJC-1295, Ipamorelin, Epitalon, and more. For sourcing standards, see our peptide purity and storage and handling guides.

How we test, source, and ship

Every batch we list moves through the same vetted pipeline: synthesis at audited contract manufacturing partners, independent third-party HPLC purity verification, mass-spectrometry confirmation of identity, and lot-level documentation that we retain and make available on request. Compounds that fall short of our ≥98% purity threshold do not get listed — they get rejected at intake and returned. Lyophilized vials are stored under stability-appropriate conditions, packed with handling instructions, and dispatched with tracked carriers from our US-based facility. Cold-pack handling is included at no extra cost when ambient temperatures or compound stability profiles call for it.

Documentation, support, and returns

Every order is backed by accessible documentation and responsive support. Reply to your order confirmation with "COA, please" and we'll send the lot-specific Certificate of Analysis. If a vial arrives damaged or you have a question about reconstitution or storage, our team typically responds within one business day. Full terms — including our refund and reshipment policy for damaged or undelivered orders — are documented on our refund policy and terms of service pages, and we encourage every researcher to review the storage and handling guide before reconstituting any new compound to keep results reproducible across your study.

Featured neuroendocrine compounds

Beyond the headline recovery and longevity peptides, our Sleep & Neurological catalog includes DSIP, Semax, Selank, and Kisspeptin-10 (10mg) — a neuropeptide encoded by the KISS1 gene that is the principal upstream activator of GnRH neurons and a central regulator of reproductive neuroendocrine signaling in animal models. Browse the full Sleep & Neurological category for the supporting research context.

Featured metabolic and growth-axis compounds

For researchers studying NAD+ salvage and methyl-donor flux, 5-Amino-1MQ is a small-molecule NNMT inhibitor frequently paired with NAD+ in preclinical adipocyte and metabolic-aging models — see the supporting overview on the Longevity category page. On the growth-hormone secretagogue side, GHRP-6 Acetate remains a widely cited first-generation hexapeptide GHS-R agonist used as a comparator alongside Ipamorelin and CJC-1295 in selectivity studies; deeper context lives on the Strength & Growth category page.
