    Does nothing and the company ignore any contact
    Phentaslim is an Absolute waste of money. Does nothing it claims to. The company only allows you to message via support ticket via their website and doesn’t respond to it. Money back guarantee is a complete lie.

    Gives me sleepless nights
    I’m 30 years old, yet I look like 50. My body is too big since I’m overweight. I have been struggling with my weight for way too long that I had to look for the best weight loss supplement that would suppress my appetite and burn my belly fat which made people think that I was pregnant. I came across Phentaslim online, and after purchasing it, I would take it three times a day without a miss. I noticed that I started experiencing insomnia such that most of the night, I would end up being awake, and it was challenging to run my errands the following day. I discontinued using Phentaslim for a while, and I noticed the caffeine in it was the one causing sleepless nights. It’s not what I expected.

    Insomnia reloaded
    I don’t care anymore whether Phentaslim works or not. I just want to my normal life of sleeping at night, and not having to deal with drowsiness during the daytime when I’m supposed to be active and productive in my workplace. I purchased Phentaslim from its official website because I wanted this supplement to help me lose some weight. I can’t sleep even after taking some sleeping pills. I consulted my doctor who advised me that Phentaslim contains caffeine, and that’s the ingredient responsible for recent insomnia. I’m no longer taking the capsules. Even if I want to lose weight, but not at the expense of not getting a good night sleep.

  5. Gabrielle P




    Works but gave me palpitations
    Without a doubt I am confident that Phentaslim is an effective weight loss supplement, but I’m very concerned about the potency of ingredients that uses this I experienced scary palpitations while I was using it. I did notice increased energy levels as well as a higher body temperature and increased sweating, good indicators that I was burning more calories. The palpitations caused me to also develop severe anxiety, and I was unable to complete a proper cycle of the supplement. I may try back in the future since it is good, but scary at the same time.

  6. Tony Mcguire




    Side Effects made me stop taking it
    I could not take this for long. After a brief period of 5 days, I stopped. The caffeine made me feel different. I was not jittery but didn’t feel like myself. Although it did give me energy, I felt hazy at times. Also, I experienced a burning sensation and I think it was from the Cayenne. So it is a big no for me.
