What’s Inside Stacked AF?

1. MK-2866 (Ostarine) – Lean Muscle Growth & Bone Protection

A powerful Selective Androgen Receptor Modulator (SARM), MK-2866 supports:

• Increased lean muscle mass

• Enhanced strength and endurance

• Improved bone density

• Reduced risk of fractures and injuries

2. LGD-4033 (Ligandrol) – Strength, Size & Recovery

Another potent SARM, LGD-4033 is ideal for:

• Boosting muscle gains and strength

• Reducing body fat

• Improving recovery time

• Supporting bone health

• Lowering inflammation and cardiovascular risks

3. GW-501516 (Cardarine) – Endurance & Fat Loss

A unique PPARδ agonist, Cardarine is not a SARM but often used alongside them for:

• Enhanced aerobic performance

• Fat burning and improved metabolic function

• Increased endurance and reduced fatigue

Popular with MMA fighters and endurance athletes, Cardarine is ideal for high-output training phases and weight-cutting cycles.

4. MK-677 (Ibutamoren) – Growth Hormone Booster & Anti-Aging

MK-677 is a growth hormone secretagogue, stimulating the body’s natural GH production. Benefits include:

• Increased muscle mass

• Faster recovery

• Fat reduction

• Improved sleep quality

• Stronger bones and joints

• Potential anti-aging effects (skin elasticity, reduced wrinkles)

Stacked AF Benefits at a Glance:

• Promote lean muscle growth
• Support fat loss and body recomposition
• Boost strength and power output
• Enhance endurance and performance
• Accelerate recovery time
• Support joint and bone health
• Improve overall wellbeing and hormone balance
