Forskolin and Testosterone Levels

Dear Dr. Rassman,

Thank you in advance for reading this question. I am a 19-year old male with MPB, NW II. I am currently on propecia to combat this.

I have recently started taking a nutritional supplement called forskolin, at half the daily recommended dose, as I am worried about the possible effects on testosterone levels. A study was done and can be found here: Body Composition and Hormonal Adaptations Associated with Forskolin Consumption in Overweight and Obese Men.

My question is, if this product does legitimately increase serum free testosterone levels significantly, is this a cause for concern?

Thank you in advance

I looked at the abstract of the study that you referenced. It seems that it does increase your serum testesterone levels, although not significantly. Time frame wise, the study only looked at the effects of this supplement at 3 months. It is possible that at 6 months or a year both the placebo and the Forskolin group may have no difference in serum testosterone levels. Who knows? With an increase in testosterone levels in the blood stream you always run the risk of having more testosterone converted to DHT, and thereby having increased hair loss.
