Sigma™ Benefits
This formula targets various aspects to address suboptimal nutrient and mineral intake, androgen biosynthesis in the testes, binding protein interactions, and even stress management to support a more conducive state for maximised natural testosterone output.
Far too many people rush in and start administering exogenous hormones before exploring all the ways they could support their endocrine system through the basics like sleep hygiene, diet, exercise, stress reduction, etc.
This product is not a substitute for those basics in any capacity, but it can be a potent adjunct to help support higher testosterone levels and overall fertility metrics.
For best results, take two (2) to four (4) capsules spread throughout the day. Do not exceed four (4) capsules in any 24 hour period. Sigma Testosterone Booster should be cycled. Take daily for 1 month, then take at least 1 week off before resuming use.
Hypromellose (HPMC) capsule, microcrystalline cellulose, stearic acid.
