Recently third-party tested Stacked AF at 99.25% purity (GW-501516), 99.85% purity (MK-677), 99.73% purity (MK-2866) and 99.31% purity (LGD-4033) – please see latest Certificates of Analysis in Data Sheet section below.

Stacked AF provides the ultimate means of researching 4 science-backed actives at the same time in research proven doses.

This stack comprises of 2 potent Selective Androgen Receptor Modulators (SARMs) in the form of MK-2866 and LGD-4033 while also including GW-501516 which is a PPARδ (peroxisome proliferator–activated receptor) agonist. Completing this impressive profile of compounds is MK-677 the ever popular potent growth hormone secretagogue.

The combination of Stacked AF has been shown to provide a range of potential benefits. Which include an increase in lean muscle mass and strength, a reduction in body fat, enhanced endurance and performance, improvements in recovery time, and reduce inflammation.

In addition, it may help improve overall health and wellbeing, reducing the risk of injury, and help the building and maintenance of healthy bones and joints.

GW501516 / GW-501516 (Cardarine) is a compound that was created in the 1990s by GlaxoSmithKline and Ligand Pharmaceuticals. It is often used as a performance–enhancing supplement, as it has been found to increase endurance and reduce fatigue.

Cardarine is becoming increasingly popular, especially among boxers and MMA enthusiasts who often have to “make weight” at the same time as having to significantly increase physical fitness and cardio output. 

MK-677 / MK677 (aka Ibutamoren) is a popular supplement that can help people achieve a wide range of health and fitness goals. It is a growth hormone secretagogue, which means it helps the body to produce more growth hormone naturally.

This can help to boost metabolism, reduce fat, increase lean muscle mass, improve bone density, and boost energy levels. It can also help to improve sleep quality and reduce stress levels, while also helping to regulate hormones in the body.

In addition, MK-677 has been shown to have anti–aging benefits, with some studies showing that it can reduce wrinkles, improve skin elasticity, and improve overall skin tone. With all these potential benefits, MK-677 is an effective supplement for anyone looking to improve their health and fitness.

MK2866 / MK-2866 (Ostarine), also known as enobosarm, is a selective androgen receptor modulator (SARM). SARMs like MK-2866 stimulate steroid hormone receptors, androgen receptors which mimic testosterone. Unlike typical steroids, though, SARMs can target specific tissues, such as the muscles or bones.

MK-2866 can also help improve bone density and reduce the risk of fractures and other bone–related injuries. This can be especially beneficial for athletes who are at risk of injury due to repeated impacts and intense physical activity.

Finally, the benefits of LGD–4033 are many. It can help increase lean body mass, improve strength, and reduce fat mass. It can also help to improve bone density, which can aid in the prevention of osteoporosis. Additionally, LGD–4033 can help to reduce inflammation, improve recovery time from exercise, and improve overall physical performance. Lastly, it can also help to reduce the risk of cardiovascular disease.
