Shop

The One Peptides shop includes Research Use Only chemical reagents in lyophilized and capsule form, and laboratory accessories. Each batch is accompanied by an HPLC certificate with purity of at least 98%. The catalog currently contains over thirty products across six groups: regenerative peptides and neuropeptides, SARMs, amino acids, performance research reagents, lab accessories, and current promotions.

Before placing your first order, we recommend:

• reviewing our quality-control standards and HPLC certificates,

• using the peptide calculator to calculate the concentration and the volume to withdraw from a vial,

• reading the science blog for mechanistic context on specific compounds.

How is the catalog structured?

The shop is divided into six categories. Each has its own sorting logic and regulatory framework.

Research Peptides (Research Use Only)

Peptides are the largest category in the catalog. It includes tissue-repair peptides (BPC-157, TB-500, GHK-Cu, PEG-MGF), neuropeptides (Semax, Selank, DSIP, Oxytocin), melanocortin peptides (PT-141, Melanotan II), GH-IGF1 axis peptides (CJC-1295 with DAC and without DAC, Ipamorelin, GHRP-2, GHRP-6, HGH Fragment 176-191), GLP-1 pathway peptides (Semaglutide, Retatrutide, GLP-1/GIP), and longevity peptides (Epithalon, Kisspeptin-10).

All peptide items are delivered as lyophilized material for reconstitution in bacteriostatic water. Regulatory status: research-use chemical reagents only. They are not medicinal products or dietary supplements.

SARMs and other compounds in capsules (RUO)

SARMs are selective androgen receptor modulators. In our catalog you will find four widely studied compounds in capsules, of which only MK-2866 (Ostarine) is a SARM: MK-677 (Ibutamoren) is a GHS-R1a agonist, GW-501516 (Cardarine) a PPARδ agonist and SR-9009 (Stenabolic) a Rev-Erbα ligand. Each batch is supported by HPLC documentation, and products are offered in 60-capsule packs.

Regulatory status is the same as for peptides: Research Use Only reagents.

Amino Acids — RUO research reagents

Amino acids are laboratory materials organised by chemical composition, including L-Carnitine in two strengths (200 mg and 600 mg). Active products in this category are Research Use Only reagents, not dietary supplements.

Performance — RUO research reagents

Performance groups compounds from different mechanistic classes — a shared catalogue category does not imply a shared pharmacological class. All active substances in this category are Research Use Only chemical reagents and are not intended for consumption or use in humans or animals.

Laboratory accessories

Accessories include materials needed for work with lyophilized peptides in laboratory settings. The key item is Bacteriostatic Water 10 mL, a standard solvent for RUO peptide reconstitution. Additional sterile tools are planned.

Promotions

Promotions are a rotating list of products with temporarily reduced prices. The list is updated regularly, so check this category before placing planned orders.

Quality control standards

Every product leaving our warehouse goes through a three-step quality control procedure: batch identification, analysis and documentation, and release for sale. The same standards apply across the entire catalogue, regardless of category:

HPLC ≥98%. High-performance liquid chromatography with UV detection: the main peak area must account for at least 98% of the total chromatogram peak area. Batches below this threshold are rejected.

MS confirmation. Mass spectrometry confirms structural identity by comparing measured molecular mass against expected theoretical mass. Two independent analytical methods in one document.

COA per batch. Certificate of Analysis is issued for every batch individually. PDF reports with chromatogram and MS spectrum are available from product pages and the quality-testing section.

Cold chain 2-8°C. Temperature-controlled handling from synthesis through delivery. Storage and shipping flow are monitored end-to-end.

Batch traceability. Batch ID is recorded in three independent places: vial label, invoice record, and COA document.

How to navigate the catalog

The shop offers three practical entry paths, depending on where you start.

Category path. If you know you need regenerative peptides, neuropeptides, or SARMs, go directly to the relevant category page.

Educational path. If you want mechanistic background first, start with the science blog. Articles are linked with literature references and then to related products.

Practical path. If this is your first time working with lyophilized peptides, begin with practical resources: the research peptide handling guide, bacteriostatic water overview, and peptide calculator. This helps estimate required peptide quantity and solvent volume before purchase.

Regulatory status in one catalog

Two different regulatory frameworks coexist within one store. This distinction matters for product descriptions, claim language, and documentation format.

• Peptides, amino acids and compounds in capsules: Research Use Only status. Chemical reagents intended exclusively for laboratory use. Not medicinal products, not dietary supplements, not foods.

• Accessories (bacteriostatic water and lab tools): technical products outside pharmaceutical and food-supplement frameworks.

The catalogue separates active substances from laboratory accessories and does not present any active product as a dietary supplement.
