Important Notice

This listing contains two different product types supplied for separate purposes:

• Stacked AF products are supplied strictly for laboratory research purposes only
• PCT is a sports nutrition supplement supplied for general nutritional use

High Purity Stacked AF – 4 Way Compound Formula

Stacked AF combines 4 widely referenced investigational compounds into a single, clearly dosed capsule format:

• 10mg MK-677 (Ibutamoren)
• 10mg MK-2866 (Ostarine)
• 10mg GW-501516 (Cardarine)
• 4.5mg LGD-4033 (Ligandrol)

Compound Overview

Stacked AF brings together 4 compounds that act through different biological mechanisms:

MK-677 (Ibutamoren)

has been widely studied for how it influences growth hormone signalling within the body. In controlled settings, it has been examined for its ability to:

• Increase measurable growth hormone (GH) and IGF-1 levels
• Support lean tissue development pathways
• Support fat metabolism signalling
• Support recovery-related hormonal activity
• Promote collagen-associated processes linked to skin and connective tissues
• Associated with better sleep quality in research settings
• Studied as an oral option instead of injectable GH
• Studied in relation to age-related hormone decline

MK-2866 (Ostarine)

In controlled settings, Ostarine has been examined for its ability to:

• Linked to increases in lean muscle tissue during calorie-controlled phases
• Associated with helping preserve muscle while dieting
• Studied for supporting strength-related performance markers
• Examined for its role in muscle maintenance during recovery periods
• Referenced in research exploring bone density signalling
• Known for selective activity in muscle tissue rather than the whole body

GW-501516 (Cardarine)

Cardarine has been widely studied for how it influences the body’s energy systems. In controlled settings, it has been examined for its ability to:

• Support the body’s shift toward using fat as a primary fuel source
• Enhance fat-utilisation signalling pathways
• Promote endurance-related signalling pathways
• Influence training volume tolerance
• Influence cellular energy efficiency
• Support lipid metabolism markers
• Enhance oxidative capacity in skeletal muscle
• Influence how the body manages fuel during calorie-controlled conditions

LGD-4033 (Ligandrol)

LGD-4033 has been widely studied for its selective interaction with muscle and bone tissue:

• Targets muscle receptors for focused lean tissue support
• Studied for its role in lean mass and strength signalling
• Selectively interacts with muscle and bone tissue
• Supports structural muscle development pathways
• Explored for muscle retention during calorie-controlled phases
• Known for its precision receptor activity profile

Mechanism Summary

Stacked AF combines:

• A compound examined for growth hormone pathway signalling
• A compound studied for how it influences the body’s energy systems
• Two compounds studied for selective androgen receptor interaction

Because these mechanisms differ, they are frequently analysed together when examining muscle-related and endocrine signalling systems in controlled environments.

Published scientific literature discussing MK-677, MK-2866, GW-501516,  LGD-4033, and related signalling mechanisms can be accessed via the PubMed database.
