[Featuring a New Industry- 주목 Ingredient] 24-Hour Fitness Gym "AC FITNESS" Launches Original Protein Supplement Containing '8PN' to Suppress Muscle Atrophy!

AC FITNESS Minami-Urawa, a 24-hour fitness gym operated by our group company, Disc City Entertainment Co., Ltd. (Headquarters: Yokohama, Kanagawa; Representative Director: Hiroaki Mita), is launching a long-awaited original protein supplement (in strawberry and chocolate flavors) containing the latest functional food ingredient, "8PN (8-Prenylnaringenin)."

*Available exclusively for in-store purchase at AC FITNESS Minami-Urawa.

🔶 A New Concept in Protein: "Protect and Enhance" Your Condition Conventional protein supplements are generally designed to promote "muscle synthesis" in conjunction with intense exercise. However, AC FITNESS Minami-Urawa has also focused on challenges such as muscle loss during busy periods when members cannot visit the gym, and age-related muscle atrophy (sarcopenia).

We have incorporated 0.1mg per serving of "8PN (8-Prenylnaringenin)," a notable ingredient found in "AstroHop®," a hop-derived functional component developed by Daicel Corporation. We believe that the shortcut to an ideal physique lies not only in maximizing training results but also in how well one maintains muscle condition during "non-exercise time," such as during work, injury, or rest days. This led to the development and sale of this original protein blend.

🔶 Three Product Features 1. "8PN" Formulation Supports Training Efficiency and Maintenance on Rest Days The ingredient "8PN" is said to work by suppressing the expression of the muscle protein breakdown marker (Atrogin-1). In addition to an "offensive" approach that increases amino acid uptake into skeletal muscle—potentially improving muscle synthesis rates from training by up to 30%—it also possesses a "defensive" function that suppresses muscle breakdown and prevents atrophy even without exercise. This supports muscle condition maintenance across all phases, whether for those engaged in hard training, those on rest days due to a busy schedule, those recovering from injury, or those concerned about age-related muscle decline.

2. Carefully Crafted Flavors for Daily Consistency We have pursued a natural taste that is easy to incorporate into daily life by minimizing the flavor profile typical of protein supplements.

Chocolate Flavor: A deep, rich taste with subtle sweetness and the aroma of cacao. It features a lingering aftertaste reminiscent of high-quality chocolate that you won't get tired of. Strawberry Flavor: Utilizes the natural sweet and sour taste of strawberries while smoothing it out. It has a refreshing mouthfeel that can be enjoyed in any situation.

3. Excellent Cost Performance (3,520 yen including tax) Despite containing high-quality ingredients, we have achieved a price point that is more affordable than competing products for a 700g bag. We are committed to this pricing to ensure our members can continue their daily nutritional support without strain.

🔶 Toward Achieving Your Goals At AC FITNESS Minami-Urawa, we support our members in achieving their goals through the following courses, utilizing our new original protein and the "KETO-BHB" also sold in-store.

① Light Course (Physique Maintenance) Focuses on preventing rebound. Maintains current status with twice-monthly training and moderate dietary adjustments (light dinners).

② Standard Course (Light Additional Weight Loss) For those who want to lose another 1-2kg. Solidifies changes made over two weeks through 1-2 training sessions per week and awareness of evening carbohydrate intake.

③ Body Make Course (Maximizing Change): Continues the "Burn-Build Diet." Maximizes visual changes through 2-3 training sessions per week and thorough nutritional management prioritizing protein and fats.

🔶 In-Store Sales of "KETO-BHB" In-store retail price: 4,290 yen (including tax)

BHB is a type of "ketone body," an energy substance that has recently attracted attention as an energy source distinct from carbohydrates. It is expected to be utilized in a wide range of fields, including diet, sports, and beauty.

KETO-BHB is a product developed based on the following four values, leveraging these component characteristics: 1. Rapid Action: Utilized as energy in as little as 10 minutes, supporting the suppression of excessive appetite. 2. Efficiency: Supports a metabolic state that preferentially utilizes fat, leading to a slim body in two weeks. 3. Sustainability: Supports building a body that is resistant to rebounding while maintaining muscle mass. 4. Safety: Uses natural BHB raw materials produced via fermentation technology derived from sugarcane.
