SlinMax is a glucose disposal agent that helps optimise carbohydrate metabolism by routing nutrients toward muscle tissue, so you can push workouts and lean gains. [This science-led formulation keeps quality high and puts you in charge of training.] Berberine and Banaba support the insulin mimetic action, helping allocate carbs toward muscle tissue. This brand is built on science led formulation and rigorous quality standards that put you in control of your training.

Available Sizes & Variants:

120 capsules – ideal for steady, month-long use.

Benefits & Features:

• Directs nutrients toward muscle tissue after high carb meals, supporting lean gains.
• Supports insulin sensitivity through a multi ingredient approach including berberine and alpha lipoic acid, helping glucose uptake during meals and aligning nutrients with muscle growth.
• Gymnema Sylvestre reduces sugar absorption in the gut and [may curb sugar cravings].
• Banaba extract helps reduce fat cell proliferation, supporting body composition.
• BioPerine boosts absorption.

Seven actives work in harmony to improve how your body handles carbohydrates. Berberine activates AMPK to support insulin function and glucose transport, while Banaba helps reduce fat cell growth. Gymnema lowers sugar absorption in the gut and may curb cravings, and chromium supports insulin response. Sodium R alpha lipoic acid adds antioxidant support, while BioPerine boosts absorption of these actives, helping you feel the benefits sooner. This science led formulation is produced with strict quality controls and reflects our broader wellness range, including magnesium glycinate, probiotics, and a vitamin d supplement.

The Active Ingredient Is: Berberine HCL

Berberine HCL is a plant-derived alkaloid used as a dietary ingredient to help normal metabolic processes around glucose handling inside the body. This form is commonly chosen for its properties within nutrient partitioning pathways and metabolic regulation.

Berberine HCL acts through established pathways to support how nutrients are managed after a meal, with a focus on improving the body's handling of carbohydrates and glucose within healthy limits.

What Berberine HCL Does?

Berberine activates AMPK, which regulates insulin and glucose transport, enabling glucose uptake into muscle cells via GLUT-4 transporters.

This mechanism supports normal carbohydrate metabolism and energy use as described in EFSA-aligned discussions of nutrient function.

Performax Labs is the brand we rely on for evidence-based formulation in performance nutrition, and SlinMax shows their focus on insulin mimetic science. This brand's approach to bringing together clinically relevant actives into one, synergistic formula lines up with our aim for clear, results-driven products that help nutrient partitioning during high carbohydrate intake.

Our expert team of doctors, nurses, and nutritionists assessed Performax Labs for its clear mechanism of action and the targeted ingredient blend that steers nutrients toward muscle tissue. The product’s design highlights multiple insulin-sensitising pathways and leans on well-known actives like Berberine, Banaba, and Gymnema Sylvestre, with BioPerine to boost bioavailability. This synergy mirrors a thorough formulation ethos focused on purity, potency, and practical dosing strategies.
