What is Stacked AF?

Stacked AF is a comprehensive research stack combining four popular research compounds into one convenient capsule formula. By bringing together MK2866, MK677, GW501516 and LGD4033, researchers can investigate several biological pathways simultaneously rather than purchasing each compound individually.

Unlike single-compound products, Stacked AF combines two Selective Androgen Receptor Modulators (SARMs), one growth hormone secretagogue and one PPARδ receptor agonist to create a diverse research formula.

Compound Breakdown

MK2866 (Ostarine) – 10mg

MK2866 is a Selective Androgen Receptor Modulator (SARM) researched for its selective interaction with androgen receptors found primarily in muscle and bone tissue.

Research commonly focuses on:

• Lean muscle retention
• Strength
• Body composition
• Recovery
• Muscle preservation

MK677 (Ibutamoren) – 10mg

MK677 is not a SARM. It is a growth hormone secretagogue that activates the ghrelin receptor, stimulating the body’s natural production of growth hormone and IGF-1.

Research commonly investigates:

• Recovery
• Sleep quality
• Appetite
• Growth hormone signalling
• Lean tissue support

GW501516 (Cardarine) – 10mg

GW501516 is not a SARM. It is a PPARδ receptor agonist researched for its influence on energy metabolism and endurance.

Research commonly focuses on:

• Endurance
• Fat oxidation
• Cardiovascular performance
• Energy utilisation
• Exercise capacity

LGD4033 (Ligandrol) – 4.5mg

LGD4033 is one of the most researched SARMs and has been studied for its potential role in lean muscle development and strength.

Research commonly investigates:

• Muscle growth
• Strength
• Recovery
• Muscle preservation
• Body composition

Why combine these compounds?

Stacked AF brings together compounds with different mechanisms of action, allowing researchers to investigate several physiological pathways within a single product.

Researchers commonly study combinations like this for their potential roles in:

• Lean muscle development
• Physical strength
• Exercise performance
• Recovery
• Endurance
• Fat metabolism
• Body composition
• Muscle preservation during calorie restriction

As with all investigational compounds, responses may vary depending on the research model.

This product is intended strictly for laboratory research and analytical purposes.
