How It Works

Testosterone is the fundamental androgenic hormone responsible for driving muscular recovery, strength development, and physical endurance. While total testosterone reflects the overall amount produced, only unbound "free" testosterone can freely enter muscle tissue to trigger protein synthesis and performance adaptations.

MuscleTech AlphaTest Extreme combines clinically validated doses of boron citrate with standardised fenugreek extract and bioavailable zinc to elevate circulating free testosterone while supporting natural hormone regulation. The addition of brassica oleracea powder (a natural source of brassica compounds) assists in maintaining a favourable testosterone-to-estrogen balance, ensuring you get clean, full-spectrum hormonal support for intense workouts and faster recovery.

Recommended Use

Take 1 serving (2 rapid-release capsules) with a glass of water twice daily. For best results, consume your first serving in the morning with a meal and your second serving in the mid-afternoon or 30 to 45 minutes prior to training. Do not exceed 4 capsules within a 24-hour period.
