Research Chemical (researchchemical.com) is a U.S.-based research compound supplier with over 53 active listings on Peptides.SO, occupying a distinctive cross-category niche in the domestic research market. The catalog leads with selective androgen receptor modulators (SARMs) — including liquid solutions, capsule formats, and preformulated stacks — and extends into research peptides, GH-axis compounds, NAD+, and ancillary agents. For researchers who require SARMs, peptides, and metabolic compounds from a single domestic source, Research Chemical provides the broadest multi-category catalog verified in this review cohort.
Company Overview
Research Chemical's name reflects its broad-spectrum positioning: rather than specializing in peptides alone, the company covers the full research chemical space including SARMs, nootropic compounds, hormonal research agents, and peptides. This positions it as a potential one-stop source for research programs studying androgen receptor biology alongside growth hormone axis pharmacology — a combination that frequently arises in muscle biology, bone density, and metabolic research contexts.
The researchchemical.com domain gives the company strong branded visibility in search contexts where researchers look for SARMs and research chemicals broadly. The catalog confirms a research-only orientation with clear disclaimers, and the domestic U.S. base means compliance with U.S. research compound regulations.
Catalog & Products
SARMs Research: The Catalog Core
SARMs (Selective Androgen Receptor Modulators) are the primary catalog category at Research Chemical, offering some of the broadest single-vendor SARM coverage of any supplier verified in 2026.
MK-677 (Ibutamoren): Multiple dose formats of MK-677, a non-peptide ghrelin receptor agonist that stimulates GH and IGF-1 secretion through GHS-R1a receptor activation. MK-677 is notably studied as an oral-route GH secretagogue — unusual in the GHRP class, which typically requires injection. Research has examined MK-677 in growth hormone deficiency models, sleep quality effects (GH is released primarily during slow-wave sleep), muscle mass preservation in caloric deficit, and bone density in aging models. The liquid format at $2.60/mg (25mg/mL) positions it competitively for liquid SARM researchers.
LGD-4033 (Ligandrol): High-affinity SARM with strong anabolic selectivity toward muscle and bone tissue androgen receptors. LGD-4033 has been extensively studied in lean muscle mass research, bone density maintenance models, and SARM comparative pharmacology. Its binding affinity for ARs in muscle and bone is approximately 20× greater than in prostate tissue, making it a precision tool for tissue-selective androgen receptor biology research.
RAD-140 (Testolone): Another high-affinity SARM studied in neuroprotective contexts (brain androgen receptor activation) as well as muscle and bone biology. RAD-140's neuroprotective research application — particularly in models of Alzheimer's disease biology — distinguishes it from the pure muscle-biology SARMs like LGD-4033.
YK-11: A steroidal SARM and partial androgen receptor agonist that also inhibits myostatin (GDF-8) through mechanisms not fully dependent on the androgen receptor. YK-11's dual mechanism — SARM activity plus myostatin pathway inhibition — makes it a complex pharmacological probe for researchers studying the interaction between androgen receptor signaling and myostatin-regulated muscle mass biology.
Andarine S4: A SARM with partial androgen receptor agonist activity studied in bone density and muscle mass research. Available in liquid solution at $1.10–$1.20/mg (50mg/mL).
RU-58841: A nonsteroidal anti-androgen studied specifically for androgen receptor activity at the scalp/hair follicle level — an application distinct from the anabolic muscle biology focus of most SARMs. RU-58841's research application is scalp androgen receptor biology in the context of androgenic alopecia models, making it a specialty catalog entry for hair follicle biology researchers.
Cardarine (GW-501516): A PPARδ (peroxisome proliferator-activated receptor delta) agonist studied for mitochondrial biogenesis, fatty acid oxidation, and endurance metabolism effects. Cardarine is not technically a SARM — it activates PPARδ rather than the androgen receptor — but is frequently cataloged alongside SARMs due to overlapping market positioning.
SR-9009 (Stenabolic): A synthetic Rev-ErbA agonist studied for circadian rhythm biology effects, mitochondrial content regulation, and metabolic rate modulation. Rev-ErbA is a nuclear receptor that regulates the CLOCK/BMAL1 circadian machinery; SR-9009 activation simulates the metabolic effects of a circadian phase that favors mitochondrial biogenesis and fatty acid oxidation over lipid storage.
Ostarine (MK-2866): The most studied SARM in peer-reviewed clinical literature, with completed Phase 2 trials in muscle wasting and bone density. Ostarine's established pharmacological profile makes it the primary reference compound for comparative SARM pharmacology research.
Preformulated SARM Stacks: Multi-Mechanism Research Tools
Research Chemical offers preformulated SARM stacks — a catalog feature that simplifies procurement for researchers studying multi-mechanism androgen receptor biology:
RAD-140/LGD-4033 Stack: Combines two high-affinity SARMs with complementary tissue selectivity profiles. Both target muscle and bone AR, but their differing binding kinetics and selectivity profiles enable researchers to study additive or synergistic anabolic receptor biology.
RAD-140/Cardarine Stack: Combines SARM-mediated androgen receptor activity (RAD-140) with PPARδ agonist metabolic biology (Cardarine) — relevant for researchers studying the intersection of androgen signaling and fatty acid oxidation in body composition models.
SR-9009/Cardarine Stack: Combines Rev-ErbA and PPARδ agonism for dual-mechanism circadian/metabolic biology research. Both compounds activate transcriptional programs related to mitochondrial function and fatty acid oxidation, potentially through synergistic pathways.
Ostarine/Cardarine/SR-9009 Triple Stack: The broadest SARM-adjacent stack, combining established AR modulation (Ostarine) with two metabolic transcription factor agonists. Researchers studying multi-pathway metabolic biology in a single experimental model find the pre-formulated stack format reduces preparation complexity.
S4 (Andarine)/Cardarine Stack: SARM/PPARδ agonist combination for researchers studying androgen receptor-PPARδ pathway interaction.
RAD-140/RU-58841 Stack: Positions androgenicity research at the scalp biology level — an unusual combination targeting anabolic AR signaling (RAD-140) alongside scalp-selective AR antagonism (RU-58841) for researchers studying tissue-selective androgen biology in hair follicle models.
Peptide Research Coverage

NAD+ Research
NAD+ with Reconstitution Kit: Nicotinamide adenine dinucleotide for cellular energy metabolism, sirtuin activation, and PARP biology research. The inclusion of reconstitution kit simplifies laboratory preparation workflow. NAD+ research has expanded significantly in the 2023–2026 period, with particular interest in aging biology, mitochondrial function, and neurodegenerative disease models.
Pricing Analysis
Research Chemical's pricing structure varies significantly between its SARM liquid and peptide segments:
SARM/Liquid Solutions (per-mg cost):

| Andarine S4 | 50mg/mL | — | $1.10–$1.20/mg |
| RU-58841 | 50mg/mL | — | $1.20/mg |
| MK-677 | 25mg/mL | — | $2.60/mg |
Peptide Vials (per-mg cost):
| Compound | Size | Price | Per-Mg |
|---|---|---|---|
| Melanotan I | 10mg | $50 | $5.00/mg |
| PT-141 | 10mg | $55 | $5.50/mg |
| GHRP-6 | 5mg | $55 | $11.00/mg |
| KPV | 5mg | $55 | $11.00/mg |
| AOD-9604 | 5mg | $75 | $15.00/mg |
The SARM liquid pricing at $1.10–$2.60/mg is highly competitive for solution-format SARMs. Peptide pricing is in the mid-range for the compounds listed.
Quality & Testing Standards
Research Chemical follows third-party analytical testing standards for both its SARM solutions and peptide catalog: HPLC purity characterization and mass spectrometry identity confirmation per batch, with COA documentation available. For SARM liquid solutions, concentration accuracy (mg/mL verification) is particularly important alongside purity, as dosing precision in liquid format depends on both factors.
The breadth of the catalog — covering SARM solutions, peptide vials, capsule formats, and stacks — creates quality verification complexity: each format type has its own analytical considerations. Researchers should request COA documentation appropriate to the specific format being procured.
Shipping & Customer Service
Research Chemical ships domestically within the United States with standard 1–3 business day processing. The diverse catalog formats (liquid solutions, lyophilized vials, capsules) ship with format-appropriate handling: peptide vials with cold-chain insulation, SARM solutions at ambient temperature as appropriate for solvent-based preparations.

Verdict
Research Chemical is the strongest recommendation in this review for researchers who need SARMs — particularly those studying androgen receptor biology, metabolic biology via Rev-ErbA/PPARδ pathways, or multi-mechanism SARM stacks — alongside growth hormone and tissue healing peptides. The preformulated stacks are a genuine procurement convenience, and the breadth of SARM coverage (8+ individual SARMs plus 6 preformulated stacks) is unmatched among the vendors reviewed here.
Researchers whose program focuses exclusively on peptide biology (GLP receptor agonists, GH secretagogues, tissue healing compounds) will find Research Chemical's peptide pricing and catalog depth uncompetitive relative to dedicated peptide specialists. But for the SARM-plus-peptide research program, Research Chemical is the natural single-source choice.
