M-Stak - a complex containing functional substances that will elevate your workout

M-Stak is a complex workout booster that contains amino acids, adaptogens, stimulants and other functional substances. Its formula is designed to take your training efforts to the next level. It opens with AM Complex 1, which contains BCAA amino acids in the form of l-leucine, l-valine and l-isoleucine. These are essential amino acids that enhance the regenerative and anabolic potential of the entire blend. Next, AM Complex 2 contains milk whey, kudzu powder (Pueraria spp.) and Siberian ginseng extract (Eleutherococcus senticosus). The latter is one of the adaptogens, which are substances generally associated with body resilience and physical performance.


Next, there's AM Complex 3 containing Lagerstroemia speciosa extract, which is generally associated with glucose levels. It is supplemented by fenugreek extract (Trigonella foenum-graecum), which is useful in the care of the sex hormone testosterone. It is then involved in many processes in our body and participates in processes related to muscle size and strength. Lipoic acid is also present in this complex, which along with the ginger powder is known for its beneficial effects. 


The formula concludes with AM Complex 4, which consists of guarana, kola nut powder with caffeine, as well as a functional dose of caffeine itself. The latter is also one of the most well-known stimulants, which are very popular in the fitness world. This is because it can energize the body both before a workout and during a busy day. It is regularly found in energy drinks or pre-workout mixes and is also a natural part of coffee. M-Stak is thus a comprehensive supplement that fits perfectly into the mosaic of a workout routine. It will be appreciated by athletes, bodybuilders, fans of an active lifestyle and anyone who wants to give the maximum during their workouts.
