Competitive Edge Formestane is product that was hard to find a whole lot of research on. This is in large part because it has been discontinued. However, there is still some information floating around out there. Originally, this supplement was a topical tongue spray created to hamper the conversion of testosterone into estrogen by inhibiting aromatase enzymes. Competitive Edge Formestane was thus designed to create a predominantly androgenic hormonal balance within athletes. From much of the customer feedback we read, it was rather effective. That has ask asking: why was it discontinued?

Competitive Edge Formestane’s Ingredients

Competitive Edge Formestane’s only active ingredient was a compound called 4-hydroxyandrostenedione. According to some resources this ingredient was considered a prohormone. Others claimed it was not since it was meant to stack with other prohormones to diminish estrogen levels. But whatever it was, research showed that this compound has the ability to effectively fight estrogen in breast cancer patients. By blocking the synthesis of estrogen, Competitive Edge Formestane can help sustain higher levels of testosterone making it easier for the body to experience anabolic boosts in muscle growth, strength, and fat loss.

With its ability to block the conversion of testosterone into estrogen, it could also be used as part of PCT (post cycle therapy) regimen. This means that Competitive Edge Formestane could be stacked with other prohormones to keep estrogen side effects to a minimum. Too much estrogen in a man’s body can lead to man-breasts, balding, water-retention, and severe acne.

Conclusion

As is the case with many prohormones, Competitive Edge Formestane was eventually discontinued. This is probably because its main ingredient (4-hydroxyandrostenedione) was too close to an already banned prohormone called 4-androstenedione. If it’s banned you can assume that it’s probably effective but it probably can come with some heavy side effects. If you’re willing to take the risk, there are probably some sites that still have some of this product in stock.
