🔶A New Concept in Protein: "Protecting and Enhancing" Your Condition

Traditional protein supplements typically focus on promoting "muscle synthesis" in conjunction with intense exercise. However, at AC FITNESS Minami-Urawa Branch, we are also addressing challenges such as muscle strength decline during periods when busy schedules prevent gym visits, and age-related muscle atrophy (sarcopenia).

We have incorporated 0.1mg of "8PN (8-Prenylnaringenin)," a notable ingredient found in "Astrohop®," a functional ingredient derived from hops developed by Daicel Corporation, per serving. We believe that the key to achieving an ideal physique is not only to maximize the effects of training but also to maintain a high level of muscle condition during times when one is not exercising, such as during work, recovery from injury, or rest days. This philosophy led us to develop and launch our original protein formulation.

🔶Three Features of the Product

1. Supports Training Efficiency and Maintenance on Rest Days with "8PN" Formulation

The ingredient "8PN" is said to suppress the expression of Atrogin-1, a marker for skeletal muscle protein breakdown. In addition to the "offensive" approach that enhances amino acid uptake into skeletal muscle, potentially increasing muscle synthesis rates from training by up to 30%, it also possesses a "defensive" function that inhibits muscle breakdown and prevents atrophy even without concurrent exercise. This supports the maintenance of muscle condition in all phases, not only for those engaged in intense training but also for individuals experiencing muscle strength decline due to busy schedules, recovery from injuries, or aging.
