Research Peptides in the USA

Every catalogue compound is available for the United States delivery — GLP-1 receptor agonists (SM, TZ, RT), growth-hormone secretagogues (CJC-1295, ipamorelin, tesamorelin, MK-677 reference material), regenerative compounds (BPC-157, TB-500, GHK-Cu, KPV) and mitochondrial peptides (MOTS-c, SS-31), in 2 mg, 5 mg, 10 mg and 15 mg vial formats depending on the compound.

Alongside the vials, a US parcel contains the printed certificate of analysis for that exact batch, the batch and lot numbers matching the vial cap, compound-specific reconstitution notes and a research-use declaration. Bacteriostatic water, sterile water, mixing vials and syringes can be added to the same order so nothing is missing on arrival.

Nothing ships to the United States on a manufacturer's word. Each batch goes to an independent analytical laboratory — Janoshik Analytical by default, with a second orthogonal laboratory used where the chemistry warrants confirmation by another method or where a US institution names an accredited lab of its own.

Release specification is a main HPLC peak of 99.0% or better, a mass-spectrometry molecular weight matching the target, and water content inside the published range for the compound. A batch that misses specification is not released into the US channel regardless of demand, and the report itself is published on our lab reports page so you can read it before ordering rather than after.

US orders leave our European hub on a tracked service with a typical 5–18-business-day international window, covering all of the United States including New York, Los Angeles, Miami, Chicago, Houston, Dallas, San Francisco, Boston, Seattle, Austin, Denver, Atlanta, Phoenix, Philadelphia and the broader US research community. Tracked international dispatch is handled in temperature-buffered packaging; the research-use customs declaration ships with every US package. Residential, co-working and registered research-entity addresses are all accepted, and express handling can be arranged for time-boxed projects.

Vials travel in temperature-buffered mailers sized for the US transit window. Lyophilised material tolerates the journey well; refrigerate at 2–8 °C once it lands, or hold at −20 °C if the batch will sit unused for more than eight months.

Reconstituted with bacteriostatic water (0.9% benzyl alcohol), most analogues hold a roughly 60-day in-use window under refrigeration. Sterile water is fine for same-day work but should not be kept for repeat use. Aliquot before freezing anything.

The most common cause of measurable potency loss in long-acting analogues is repeat freeze-thaw cycling, not shelf age. Swirl rather than shake, keep reconstituted vials out of direct light, and record the reconstitution date against the batch number. Our compound storage guide covers the per-compound windows in more detail.

Everything listed is supplied as in-vitro and preclinical reference material. It is not a medicine, is not approved for human consumption in the United States, and is not dispensed against a prescription. US research-use peptide supply sits outside FDA-approved medicinal-product regulation; nothing on the Regena catalogue is approved by the FDA for human use.

The research-use declaration travels with every US package and is written to satisfy both the courier and an internal procurement record. Researchers remain responsible for compliance with their own institutional ethics framework and local handling rules; documentation questions can be pre-cleared with our team before anything is dispatched.

The US hosts the world's largest independent and academic research-peptide community — Boston's biotech corridor, the Bay Area research cluster, the NIH-funded ecosystem and a dense network of private research clinics and longevity practices across every major metro. Regena's batch documentation is formatted to slot directly into US institutional procurement workflows.

For longer US programmes — longitudinal stability work, comparator panels, multi-cohort protocols — inventory can be reserved against a project timeline so availability does not shift mid-study. Material Safety Data Sheets, Certificates of Origin and Certificates of Conformity are issued on request before dispatch, and invoicing can be formatted for institutional procurement systems.

A free 20-minute call is open to any US researcher: which compound fits the question being asked, what is actually in stock, how to read the certificate, and how to plan reconstitution. The scientific team takes these directly — there is no sales layer between a US laboratory and the people who release the batch.

Requests go through the consultations page and are answered within one working day, including express dispatch quotes, inventory reservations and bespoke documentation.
