Fastin is a relatively new weight loss supplement that has been receiving a lot of positive attention in recent months. That's because of a ton of positive user feedback from satisfied customers.
What's so special about Fastin? Well, for starters – this is not one of those simple weight loss products. Nope! Not only will Fastin help you lose weight, it will also help you during the actual process of eating less (appetite reduction) and working out more (energy boosting effects).
With that said, in the review below, you will find a lot more information about its effects, side effects… and most importantly – ingredients. So, without further adue, let's kick things off and check out Fastin's formula!
What's inside Fastin?
If you are interested in the formula behind this supplement, then you should start off by taking a closer look at its official ingredients list:
Unfortunately, the exact dosages of ingredients from the proprietary blend are not showed. However, the total dosage ranks up to 245mg and, considering the sheer power of ingredients inside, I'd say it is more than enough to make a difference!
Apart from being used as a food treat, theobromine (or rather its originating plant – cocoa) is also used for lowering blood pressure and cholesterol levels.
Derived from bitter oranges, Synephrine can effectively promote weight loss when combined with high caffeine intake and plenty of workouts.
Originates from a Yohimbe tree that's a common occurrence in certain parts of Africa. When it comes to effects, Yohimbine effectively promotes weight loss and increased athletic performance.
100mg of Caffeine Anhydrous
While 100mg of Caffeine Anyhydrous is not a huge dosage, it will still provide a decent energy boost that will last throughout the day.
What side effects could occur with using Fastin?
As far as side effects are concerned, the majority of people won't feel a thing. However, it's recommended that people with higher blood pressure steer away from this one as it can lead to further increase which, as I'm sure you already know, can result in serious issues. On top of higher blood pressure, some users have also complained about short and mild headaches and rapid heart beat, most likely caused by caffeine.
What about Fastin user feedback?
Now let's take a closer look at user feedback for Fastin. As I've mentioned earlier, people are loving this supplement so don't be surprised at how positive these Fastin review are going to be.
“Love this product! Losing weight without any complications, i'm just not hungry. Love the fast service from a1supplements! Have never had issues with this company!
“I just started taking this again, the first time I took it I went from a size 12 to a size 5/6. I was ecstsatic. Then the formula changed and did nothing but make my heart race and feel sick. When I found the website with the original formula I am excited to see if it works again. After a month I'll review again. Just started taking it and so far no racing heart or feeling sick, yay!!!!”
“Being someone who has never gotten over the removal of ephedra from weight loss and energy pills I have looked for a suitable substitute for years, I have to say I've found it. Ephedra produces the same “mood elevation” this product promises, and although not ephedrine-based, it feels the same as I remember. Caution though is the key, the first dose had my heart-pounding for the first half hour, must assess your tolerance, and don't take a red bull like I did, but I'm a machine, what else can I say?”
To top it all off, here's one negative review that will put the above in contrast:
- Product from a proven brand
- Powerful ingredients
- Chance of higher blood pressure and mild headaches
Final words on Fastin
As you could see for yourself, there are plenty of positive reviews for Fastin. It's not a surprise since it sports a potent formula that not only promotes weight loss but helps you eat less and achieve more during your workouts.
So, for all of you battling with few extra pounds, Fastin seems like a great solution. Realistically speaking though, it's a bit pricey, especially if you're looking in the long run of things. However, price/value ratio is absolutely brilliant since I doubt you'll get a 100% legal, ephedra-free weight loss with energy boosting properties for less than $50.
