26 Fastin-XR Reviews

  • Reduces stress, controls appetite....but haven’t lost weight.
    Rita (Verified Purchase)

    Seems to work like Phenterimine. Unfortunately in my case, it relaxes me. People with Add have the opposite side effect so instead of energy, it calms us down and reduces stress. And it really does relax me like no other ..but without making me sleepy. Perhaps it can reduce cortisol levels that contribute to belly fat. I don’t experience any jittery or increased heart rate. It also reduces my appetite so I don’t crave as much. I haven’t lost much weight with it though. Now, I just buy it because it reduces stress.

  • Donna Oyadomari

    Unfortunately this product caused me to have an allergic reaction. Please let me know how to return the unused product. I apologize for this, however, I am unable to take anymore.

  • Shana

    I have tried both the 45 count and the 90 count of fastin-Xr and the 45 count seemed to work ALOT BETTER then the 90 count. I was not hungry and got full quickly. Taking 1 pill at a time instead of 2 in the morning and 1 in the afternoon worked better for me, good inc in energy without the jitters when taken that way. I bought the 90 count when I couldn’t find the 45 count anywhere and didn’t feel anything at all with them.

  • These pills are awesome and I will definitely recommend them.
