Because there have been multiple version of this product, some are confused on that the actual difference is. The current formula has been around since the beginning of 2017. It's main ingredient is DMHA, but this could change. Due to the issues with the FDA and DMAA, Metabolic Nutrition decided to remove this ingredient, along with every other manufacturer. While many customers were upset about this, the newest formula is stronger than ever and is now a top fat burner in our store.

    Q: Can Synedrex affect birth control.
    A: When taking any sort of medication like birth control, it is best to speak with your doctor. While we don't think it should have any effect, we would highly recommend speaking with your doctor, as they would be able to provide the best answer.

    Q: Can you snort it?
    A: Yes, we actually receive this sort of question. No, this product should definitely not be snorted. It should be taken in the original pill form with liquid.

    Q: What replaced it?
    A: Synedrex is now back, but for the time it was gone, a product called Synadrene replaced it. It is the closest thing to the original product. Metabolic Nutrition removed it from the market when DMAA was starting to have issues. They wanted to wait until they had a good replacement and not rush into releasing a less potent replacement.

    Q: Who makes this product?
    A: Metabolic Nutrition is the manufacturer of this product. They also make other fat burners like Thyrene and Hydravax, which are popular to stack.

    Q: Why was Synedrex banned/discontinued?
    A: It was never banned, but was discontinued. This was due to the government looking more into the use of DMAA (1 3 dimethylamylamine). Because of this, Metabolic Nutrition decided to discontinue that version of the product and replace it with DMHA. This took over a year, which is why it may have seemed the product was discontinued or banned.

    This is honestly the best weight loss product I have come across in a very long time. I personally have lost a lot of weight using it, and some of my friends have lost more than 60 pounds within a month and a half. You do get better results when working out with this product. They come a lot quicker. There wasn't many bad side effects. Sleeping was hard when I first took it, but after a couple of days that went away.


    I love the long term energy and endurance this pill allows. I does make me a bit jittery shortly after taking it, but it wears off. Otherwise I will take it with my protein. Very good appetite suppressant.


    Synedrex does everything it says!! Quality, quality, quality! I actually have to force my self to eat because I'm not hungry at all !! No jitters, great energy all day long!!
