Biological Activity

Description Andarine (GTx-007, S-4) is a selective non-steroidal androgen receptor (AR) agonist with Ki of 4 nM, tissue-selective for anabolic organs. Phase 3.
Androgen Receptor [1]
4 nM(Ki)
In vitro

Andarine stimulates AR-mediated transcription to 93% of that observed for 1 nM DHT at a concentration of 10 nM. [1]

In vivo Andarine exhibits potent and efficacious anabolic activity and results in dose-dependent stimulation of growth in prostate, seminal vesicles, and levator ani muscle with the ED50 of 0.43 mg/day, 0.55 mg/day, and 0.14 mg/day, respectively. Besides, Andarine shows no dose-dependent effect on castration-induced change in FSH, and partially suppresses LH production at dose rates of 0.5 mg/day or higher. [1] In dogs administrated by intravenous doses of Andarine (0.1, 1, 3, and 10 mg/kg), the total body clearance (CL) ranged from 7.4 mL/min/kg to 3.1 mL/min/kg, volume of distribution at steady state (Vss) is 1.39 L/kg and half-life of Andarine is 229 minutes, respectively. In addition, oral bioavailability is 38%, 62% and 91% for the 10 mg/kg, 1 mg/kg and 0.1 mg/kg doses, respectively. [2] Andarine demonstrates tissue-selective pharmacological activity and significantly decreased prostate weight to 79.4% at a concentration of 0.5 mg/day in intact rats. [3]

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
