Works for me; have been using it for a year
I have been using testosterone booster for the last few years and this is the only one that worked for me. Boosters using Vit D3 and aspartic acid as their main ingredient did not work. I have seen the increase in testosterone levels by actually measuring my blood testosterone levels. Viril X works for me in all aspects: exercise, muscle mass, less body fat, and sexually.
Positive results thus far
I have been on the supplement for just a little over a month and have had positive results in the areas of stamina and strength. It took about three weeks before we saw continuous results. I will continue taking the supplement and most likely will order again. No side effects for me.
Garbage junk scam ripoff don't buy
This stuff is pure garbage, doesn’t do a damn thing. Took the whole bottle as instructed for a month and nothing. Total scam don’t buy!
Works OK till now for me!
I have been taking this product for about three weeks now. It showed positive changes the first day and continues to show some now as well. However, I did experience stomach ache when I took the supplement directly on an empty stomach. Guess it has a high dose of ginger root, which may have caused it.
