Hi ZOE,

Short answer-SP has been reported to be anti-estrogenic, spearmint is ok, but something that does both makes more sense like, Reishi (Ganoderma lucidum),That study found that reishi mushrooms significantly reduced levels of 5-alpha reductase, preventing conversion of testosterone into the more potent DHT.

Or Peony Root - Estrogenic, blocks 5ar and pro-aromatase - Strong.

DHT is the real enemy!, I know it's confusing, certain conditions apply in your decision, like age, bmi, sex. Have you ever had a test?
