Works if you looking to last longer in sex. Be hard for long time
I'm about to turn 30 and i had all the lower testosterone level effects. My sex life was shit wouldn't last 5 mins. Felt weak all the time. So I told myself why not buy it its only 20ish dollars. I waste that at bar any night. Now i'm doing 23 years old womans. I last so long and they love it. Oh God how they love it. Its makes you so horny all the time and makes you last long in bed. I don't see a difference in lifting weights like heavy weights gains but I do work out daily and feel so strong.I went from 203 to 189lbs from taking it 2 times daily with food plus being active working out daily. (only take it with food because you wont feel it without). For me its all about pleasuring woman more then lifting. So if you struggle in the bed room then this might be your fix. Its only 20ish bucks? why not try it? I did see mood swings tho but nothing bad and less appetite .its great safe product. It didn't come in white bottle tho but clear 90 caps. My 2 cents :) have a great day!

T Booster? or Mood Booster?
I take just once a day on non-workout days. I take another 1 hr pre-workout. No recognizable differences as far strength is concerned. It seems to have leveled out my energy/mood highs and lows as a result of my workout routines. I attribute to hormone regulation. This is a staple product in my supplement use.

I KNOW this product works!!!! When I'm on it, I feel super-strong!! When it's time to cycle off, I totally feel that something is missing. Additionally, my lab results from my annual physical show that my testosterone levels are up approx. 75 points. At age 50, that is a huge gain. I highly recommend this product specifically and tribulus in general for older lifters. Thanks, GNC.

energizes without causing jitters
i noticed right away that it gave me more energy and endurance in the gym. my lifts went up 5-10 lbs in the first week. i take one in the morning daily, and then a second one before i hit the gym on workout days. although it does give you more energy, it won't make you feel jittery or wired.

Pretty Good Stuff
Works pretty well, some say its similar to USPLabs Prime, and it does have similar effects even though its not the exact same herb. Id say it works almost as good for a much cheaper price. Not quite the same initial pump from plain tribulus as you get with USP's blend, but once you get going you'll feel it.
