I started using the testrol gel about 2 months ago. I have to say, nothing has improved n the libido department, but I know it can take time. Unfortunately, I seem to be getting some unwanted side effects, low mood, fatigue and my hair seems to be thinning, certainly more hair coming out in the shower. I guess it doesnt work for everyone. Confusing when a side effect is hair loss, but low testosterone can lead to hair thinning. Not sure ifI will continue
