ACP-105 – A non-steroidal SARM developed to selectively activate androgen receptors with minimal impact on prostate tissue. Known for its short half-life and experimental status.
Androgen Receptor (AR) – A type of nuclear hormone receptor that binds to androgens (like testosterone) and regulates gene expression. SARMs selectively target ARs in muscle and bone.
Anabolism – Refers to muscle-building effects. SARMs aim to provide anabolic benefits without androgenic (masculinizing) side effects.
Bioavailability – The proportion of a compound that enters systemic circulation and is available to exert its effects. A critical factor in SARMs dosing.
COA (Certificate of Analysis) – A document verifying the purity, identity, and quality of a compound, typically issued by an independent lab. Should include HPLC, NMR, and MS data.
DHT (Dihydrotestosterone) – A potent natural androgen that SARMs attempt to mimic in target tissues without the systemic side effects.
Endocrine Disruption – Endocrine disruption refers to the process by which external chemicals interfere with the body’s hormonal (endocrine) system – often with far-reaching health effects.
Half-life (t½) – The time it takes for the concentration of a compound in the body to be reduced by half. Affects how frequently a research compound is administered. Helpful tool: SARMs half-life calculator
HPLC (High-Performance Liquid Chromatography) – A lab method used to assess compound purity by separating and quantifying chemical components. Often included in COAs. Further reading: SARMS & HPLC
PPARδ Agonist – A compound like GW501516 (Cardarine) that activates the PPARδ receptor, improving endurance and lipid metabolism – not technically a SARM.
Peptide – A peptide is a short chain of amino acids linked by peptide bonds.
RAD-140 (Testolone) – A highly anabolic SARM with a long half-life (~45 hours). Often researched for its potential muscle and neuroprotective benefits.
S-23 – A very potent SARM with strong androgenic effects in preclinical studies. Often used in aggressive research protocols.
SR9009 / SR9011 – REV-ERB agonists that modulate circadian rhythm and metabolic activity. Though sometimes grouped with SARMs, they have a different mechanism.
Tissue Selectivity – A key property of SARMs – they activate receptors in muscle and bone but spare reproductive or prostate tissue.
YK-11 – A myostatin inhibitor and partial androgen receptor agonist, often grouped with SARMs but structurally distinct.

What It Means, How It Happens & Why It Matters in Research Endocrine disruption refers to the process by which external chemicals interfere with the body’s hormonal (endocrine) system – often with far-reaching health effects. These disruptors can mimic, block, or alter hormone signals, leading to changes in development, fertility, metabolism, or even behaviour. If …
Definition: A peptide is a short chain of amino acids linked by peptide bonds. In the body, peptides act as signalling molecules, controlling everything from hormone release to tissue repair. They’re smaller than proteins and are either naturally produced or synthetically engineered for therapeutic or research use. Quick Summary Term Peptide Type Short amino acid …
Ever wondered what a “ligand” actually is when people talk about SARMs?You’ll see the word tossed around in studies, forums, and product descriptions – but what does it really mean? Let’s break it down in simple, science-backed terms.Spoiler: understanding ligands is key to understanding how SARMs work. What Is a Ligand? A ligand is simply …
Definition: Anabolic Anabolic refers to any biological process that builds up complex molecules from simpler ones – the opposite of catabolic, which breaks things down.In the context of physiology and sports science, “anabolic” typically describes the growth and repair of muscle tissue, bone density, and other body structures through increased protein synthesis and cellular regeneration. …
