Advanced Definition Kit

MK-2866 SAFETY DATA SHEET
GW0742 SAFETY DATA SHEET
S-4 SAFETY DATA SHEET

The Advanced Definition Kit is a three-compound combination formulated for preclinical investigation of recomposition and partitioning research models. It pairs two tissue-selective SARMs with a PPARδ agonist, forming a research framework focused on simultaneous lean tissue preservation and enhanced fatty acid oxidation under metabolically demanding conditions.

The mechanistic rationale combines low-androgenic AR modulation with non-androgenic metabolic stimulation. MK-2866 and S-4 together provide differentiated AR engagement that supports muscle preservation under caloric deficit, while GW0742 activates PPARδ pathways governing β-oxidation, mitochondrial biogenesis, and glucose homeostasis. The result is a research model in which lean tissue retention and adipose attenuation can be studied as concurrent rather than competing processes.

Included in this kit:

• 1 × MK-2866 | 100 pellets, 10 mg active compound per pellet
• 1 × GW0742 | 100 pellets, 10 mg active compound per pellet
• 1 × S-4 | 100 pellets, 25 mg active compound per pellet

Total: 300 pellets / 4,500 mg active compound.

Compound roles in this bundle:

MK-2866 (Ostarine) – tissue-selective SARM providing the primary muscle-preserving axis, with documented anabolic activity under simulated cachexia, disuse, and caloric deficit conditions.

GW0742 – selective PPARδ agonist contributing the metabolic axis, modulating lipid metabolism, mitochondrial β-oxidation, and adipose tissue accumulation under high-fat dietary challenge.

S-4 (Andarine) – partial AR agonist supporting contractile performance and fatigue resistance, complementing MK-2866 through differentiated AR-binding kinetics.

Combined research applications:

• Preclinical models of body recomposition under hypocaloric or high-fat dietary conditions
• Studies of lean mass preservation alongside fatty acid oxidation and adipose attenuation
• Investigation of contractile performance and endurance under combined AR and PPARδ stimulation
• Research into glucose homeostasis and insulin sensitivity in metabolic disease models
• Comparative analysis of partitioning effects relative to single-axis interventions

This kit is positioned as an advanced recomposition combination with a mild androgenic profile and pronounced metabolic activity, suited for research programmes prioritising body composition refinement over volumetric mass accrual.
