    hydroxystim, contains an ingredient which is used to enhance “men” workout, such as yohimbe extract, so my query is that is this product hydroxystim from muscletech, safe to be used only for males, or can females also use this product?

      Hey Nancy,
      Yohimbe (and Hydroxystim) is as safe for women as it is for men. That is to say that some people do experience side effects. I was one of them, in fact. It could work great for you. Just take it slow at first, like MuscleTech recommends.

    Yesterday was my first workout in quite a while. As a 25 yr old female I really haven’t done too much since high school, besides for the workout class here and there. My fiance got hydroxystim for me to try. I took one capsule before my workout yesterday. I was actually very impressed with the amount of endurance I had with the help of the hydroxystim. I was able to spend 30 minutes high intensity on the elliptical, followed by about and hour and a half of weight training. I did get a headache about half way thru, but as I was sweating ALOT I just chugged about half a gallon of water and within minutes the headache was gone. Post workout I was pretty hungry, but craved sugar so I had a large blueberry muffin and just that filled me up. My only complaint was that in the middle of the night I woke up and my pj’s were drenched in sweat and I felt extremely HOT! However, I just hopped in the shower, rinsed off and changed into something else and slept thru the rest of the night fine. I’m hoping that this will wear off and I won’t get the night sweats as badly once I my body gets a little more used to the product. So far so good with this product, so I will give another review after a few weeks or a month or so.

    taking it for one week now and feel nothing. but then again I am a serious coffee drinker and perhaps this product is not as strong as my morning cup! i play soccer semi-competatively (a little over 35 years now) and my games are late so a boost would be nice.

    Hello. I’m 23 yr old female and I try the hydroxystim and I loves this product. I was taking about 2 pills 30 min before my workout and I didn’t have any crash like effects but I did combine this with the gaspari spirodex and I dropped weight quickly while working out of course. But the combination left me some serious headaches if I didn’t take those pills in the morning and do my workout. I think I went through a caffeine withdrawal lol.
    Anyways great product for those who like cardiovascular and want a supplement they can “feel”. Cheapest I’ve found is online for like $20I a bottle.

    Hey Yuvi,
    I wouldn’t recommend that you keep using Hydroxystim without talking to your doctor first. Yohimbe can be pretty dangerous for some people, so it’s just not something you want to mess around with. Personally, I like Phen375 for fat burning. It really works, and you hear next to nothing about side effects.
