Core Labs M-Sten 60 Caps: Advanced Muscle-Building Supplement

Core Labs M-Sten is formulated to support significant muscle gains and enhanced physical performance. The combination of potent ingredients aims to promote muscle development, support liver health, and improve overall well-being.

Key Ingredients:

  • NAC (N-Acetyl L-Cysteine) – 350 mg: NAC is derived from the amino acid L-cysteine and is crucial for synthesizing glutathione, a powerful antioxidant. Glutathione neutralizes free radicals, supports the immune system, and detoxifies harmful substances in the liver. NAC also has mucolytic properties, aiding in respiratory health, and is studied for its potential benefits in psychiatric and neurological disorders due to its antioxidant effects.
  • M-STEN (2,17α-dimethyl-5α-androsta-1-en-17β-ol-3-one) – 10 mg: M-STEN is a synthetic prohormone known for its anabolic properties, promoting muscle tissue development and enhancing physical strength and muscle mass. It is popular among athletes seeking to augment muscle growth and improve performance.
  • Vitamin E (TPGS) – 10 mg: Vitamin E is a fat-soluble compound with antioxidant activities, protecting cell membranes from damage caused by free radicals. TPGS, a water-soluble form of vitamin E, improves the absorption and bioavailability of other substances. It supports immune function, cellular signalling, and metabolic processes.

Dosage, Timing, and Follow-Up:

Daily Intake: Take one capsule daily with a meal to enhance absorption.


  • On-Cycle Duration: Use for 4-6 weeks continuously.
  • Off-Cycle Break: Take at least a 4-6 week break to allow the body to recover.

Post-Cycle Therapy (PCT):

  • PCT Duration: Start PCT immediately after the on-cycle ends and continue for 4-6 weeks.
  • PCT Purpose: Restore natural hormone production and mitigate side effects from hormonal imbalances.

PCT Supplements:

  • Natural Testosterone Boosters: Fenugreek, Tribulus Terrestris, D-Aspartic Acid.
  • Estrogen Blockers: Aromatase inhibitors to prevent testosterone to estrogen conversion.
  • Liver Support: NAC (included in the product), Milk Thistle, TUDCA.
