Step One Research is a U.S.-based research compound supplier operating at s1research.net with over 40 active product listings on Peptides.SO. The "Step One" brand positioning signals accessible entry into research compound procurement — clear product organization, multiple dose format options, and coverage of the principal compound categories used in contemporary peptide research. The catalog spans metabolic research agents, GLP receptor compounds, tissue healing peptides, growth hormone-axis compounds, cognitive research peptides, immune support agents, and anti-aging compounds.
This review draws on Peptides.SO listing data and catalog analysis to assess Step One Research's position in the 2026 research compound market.
Company Overview
Step One Research's brand philosophy — accessible entry-point sourcing with clear organization — manifests in a catalog that covers standard research use cases without unnecessary complexity. The 40-listing catalog reflects practical scope: broad enough to serve most core research procurement needs, focused enough to maintain product coherence. Multiple dose format options and bundle pack availability for high-demand compounds reflect attention to researchers who run multi-vial protocols or compare dose-response relationships across cohorts.
Catalog Depth and Breadth
Metabolic Research Compounds
AOD-9604 (Advanced Obesity Drug, hGH fragment 176-191) is available in both single-vial format (5mg with reconstitution solution) and two-pack bundles (10mg total with reconstitution water). AOD-9604 is studied for its selective lipolytic properties in adipose tissue research — specifically adipocyte signaling, free fatty acid mobilization, and metabolic rate modulation — with research interest focused on its fat metabolism effects independent of the IGF-1 axis stimulation seen with full-length hGH. The bundle format provides cost efficiency for researchers running longer-duration metabolic protocols.
5-Amino-1MQ covers NNMT inhibitor research in adipocyte metabolism and NAD+ precursor biology. Tesofensine covers triple monoamine reuptake inhibition research in appetite regulation and weight management biology.
LIPO-C and LIPO-C with B12 (10mL) — lipotropic combination formulations for cellular fat metabolism research — are listed in both standard and B12-augmented variants, providing format flexibility for researchers studying lipid mobilization pathways alongside methylation biology.
GLP Receptor Research
Step One Research shows meaningful GLP receptor compound coverage:
Retatrutide (Reta 10mg) — the triple GLP-1R/GIPR/GCGR agonist (Eli Lilly LY3437943, Phase 3) — is listed for frontier metabolic signaling research.
R-GL-Peptide3 (CAS #2381089-83-2) — a Retatrutide research form designation with specific CAS registry identification — provides a second entry point for researchers working with Retatrutide-adjacent compounds and verifying compound identity through chemical registry data.
GLP3/Cagrilintide 20mg/4mg combination vial covers dual-receptor metabolic research designs combining GLP-1/GIPR/GCGR triple agonism with amylin receptor biology — one of the most pharmacologically complex metabolic compound combinations available from domestic suppliers.
S-GL-Peptide1 (CAS #910463-68-2) and T-GL-Peptide2 (CAS #2023788-19-2) extend the GLP receptor research catalog with research-designation compound entries, with CAS numbers provided for chemical identity verification.
Tissue Repair and Healing Compounds
BPC-157/TB-500 combination blends are listed in multiple SKUs and dose formats, reflecting high researcher demand for this dual-peptide healing combination. BPC-157's gastrointestinal mucosal protection and systemic healing signaling complements TB-500's actin-sequestering and angiogenic activity in tissue repair research models.
TB-500 (Thymosin Beta-4) is listed separately for researchers using the full-length Tβ-4 molecule. TB-500 Fragment 17-23 10mg — the active C-terminal fragment of thymosin beta-4 studied in cardiac tissue regeneration and wound healing acceleration — is a specialty format providing the bioactive region in isolation for researchers comparing fragment vs. full-length activity.
KPV covers alpha-MSH-derived tripeptide research in mucosal protection and anti-inflammatory signaling. AHK-Cu Cosmetic Raw 1g provides the copper peptide AHK-Cu (alanine-histidine-lysine copper complex, structurally related to GHK-Cu) in cosmetic-grade 1g raw format — a rare format specification for dermatology and skin biology researchers requiring bulk raw material.
Growth Hormone Axis
Ipamorelin 10mg covers ghrelin receptor agonist research in pulsatile GH release biology. CJC-ND 5mg + IPA 5mg combination vial provides the standard GH secretagogue dual-compound preparation in a single reconstituted format. Thymosin Alpha-1 10mg covers immune modulation and thymic peptide biology research.
IGF-1 (1-3) 1mg — the ultra-short N-terminal IGF-1 tripeptide (des-1-3-IGF-1 fragment, Gly-Pro-Glu) with high receptor affinity and CNS activity — is studied in synaptic plasticity modulation, neuroprotection, and cognitive biology research. This fragment's specific CNS activity profile distinguishes it from full-length IGF-1 and IGF-1 LR3 for researchers focused on neural IGF receptor biology.
GHK-Cu 120mg Blue/Purple Color — the blue-purple coloration characteristic of copper complexation confirms the chelated copper state — provides a high-dose GHK-Cu format for researchers running intensive copper peptide tissue modeling protocols.
Cognitive Research Compounds
Semax covers ACTH-derived heptapeptide research in BDNF induction, neuroprotection, and cognitive biology. Selank covers anxiolytic neuropeptide research in GABAergic modulation and stress biology. Both are widely studied in Russian neuroendocrinology literature and increasingly in Western cognitive biology research.
S-31-S 50mg extends the cognitive research catalog with a specialty designation compound. NAD+ pH Balanced — pH-buffered NAD+ formulation for cellular energy metabolism and longevity research — provides improved stability characteristics versus unbuffered formulations.
Anti-Aging and Longevity
B12 10mg (Liquid) covers methylcobalamin research in neurological function and methylation biology. Glutathione (1,500mg) covers redox biology and antioxidant research. SNAP-8 10mg — the cosmetic octapeptide studied in facial wrinkle modulation through acetylcholine-release inhibiting mechanisms at the neuromuscular junction — extends coverage into cosmetic peptide research applications.
Reconstitution and Ancillary Products
Bacteriostatic Reconstitution Solution and Acetic Acid 0.6% 10mL provide the standard ancillary products required for complete research protocols — coverage that ensures researchers can source both peptide compounds and reconstitution materials from a single supplier relationship.
COA Standards and Testing Quality
Step One Research provides COA documentation for catalog compounds. The presence of multiple GLP receptor research compounds with CAS registry identification (R-GL-Peptide3, S-GL-Peptide1, T-GL-Peptide2) reflects a catalog approach that prioritizes chemical identity documentation alongside purity characterization.
Researchers should request batch-specific COA documentation directly from Step One Research for precision protocol applications, particularly for the research-designation GLP compounds where chemical identity verification is a primary quality checkpoint.

Verdict
Step One Research delivers a well-organized, accessible catalog that earns distinction in two areas: GLP receptor compound depth (Retatrutide, GLP3/Cagrilintide combination, CAS-identified research compounds) and specialty format differentiation (AOD-9604 bundles, TB-500 Fragment 17-23, IGF-1 (1-3), AHK-Cu cosmetic raw). The "Step One" accessibility proposition is substantiated by clear catalog organization and multiple dosing format options that reduce procurement friction for researchers entering these compound categories.
For researchers studying metabolic biology, GLP receptor pharmacology, or tissue repair mechanisms — and particularly those who value CAS-identified compound documentation — Step One Research is a practical and distinctive 2026 supplier option.
