About The Product
Dark Metal Thrasher is a pre-workout supplement (that’s also designed to promote fat loss) by Insane Labz. It costs $54.95 for 60 serving containers, and interestingly, it comes in capsules instead of powder form like most pre-workouts.
To give you an idea of how safe and effective this product is, we’ll analyze Dark Metal Thrasher’s nutrient profile for you in the next section. But first, we’ll tell you more about the company behind it.
Who are Insane Labz?
Insane Labz are a supplements company based in the USA. They market some popular products such as Psychotic (another pre-workout).
Their ‘about us’ page on their website didn’t tell us much about their company at all. They’ve only focused on their image, as most of the page is filled with a Jason style Halloween hockey mask (we would have rather found out what year they were founded etc).
Anyway, you’re here to learn about Dark Metal Thrasher, so let’s see which ingredients are inside this product below…
Dark Metal Thrasher Ingredients Explained
Dark Metal Thrasher contains 9 ingredients overall, which isn’t a bad number to have in a supplement; we usually find that products containing over 10 nutrients are under-dosed and ineffective, so this is good.
But here’s the bad news – every ingredient inside Dark Metal Thrasher is part of a proprietary blend (we’ll expand on this below).
Anyway, now that you know why proprietary blends are one of the biggest gimmicks in the industry; we’ll take you through each ingredient inside Dark Metal Thrasher.
By the end of this review, you’ll know how safe and effective this pre-workout supplement really is.
Here’s Everything You Need To Know:
This might sound fancy, but it’s simply a patented form of juniper berry. Yes, the same stuff you add to gin and tonic.
While it might make this alcoholic beverage taste better, it’s not shown to improve your gym sessions. The only positive is that it contains anti-oxidants, so it might improve your general health.
But when you’re buying a pre-workout, the bottom line is that you want that ‘kick’ to smash your gym sessions everytime. And unfortunately, juniper berries won’t help you do this.
We don’t understand why companies add Choline Bitartate into their supplements, and it shows a lack of research on their behalf.
Basically, Choline Bitartrate hasn’t shown to be beneficial in any study conducted on it.
However, it has been commonly reported to cause your breath and sweat to smell fishy. Personally, this is something we’d rather avoid, especially as there’s no benefits in return.
For this reason, we usually try to avoid supplements containing Choline Bitartrate.
Again, this might sound fancy, but it’s simply a patented form of fulvic acid.
What’s fulvic acid? Well, it’s found in soil and is a ‘highly nutritious layer of the earth’. It can improve your general health by helping to transport vitamins and nutrients to the right places.
However, while this can improve your general health, OxyGold isn’t going to help you break any personal records in the gym.
In case you’re wondering what ‘Anhydrous’ means, it’s basically signals that Caffeine has been dehydrated into powder form (so it can be added into supplements).
When dosed under 200mg per serving, Caffeine is a key pre-workout supplement. This is because it can raise your energy, strength, endurance and focus in the gym.
However, when it’s added into a proprietary blend, it can put you at risk from jittery side effects (as you don’t know the exact amount added into products).
For this reason, we advise you to avoid pre-workouts containing proprietary blends, and Caffeine dosages above 200mg per serving.
Black Pepper Extract
Yes, this is the same stuff that you sprinkle on your food to make it taste better.
But it’s more useful than you think; Black Pepper Extract has shown to improve your digestion and absorption rate of supplements it’s added to.
Although it’s never a key addition to any product, it doesn’t cause any side effects. So it can be a useful ‘bonus’ ingredient.
Now, this is one of the worst ingredients you can find in any supplement; Yohimbe has commonly been reported to cause side effects, which is no surprise as it’s a big source of Yohimbine.
In case you don’t know, Yohimbine has been banned in numerous countries after causing harmful side effects. However, Yohimbe Extract passes through legal loopholes as it’s not directly Yohimbine itself.
As a result, companies are still able to add this ingredient into their products. But we believe it’s only a matter of time until this gets banned too.
We will acknowledge that it’s shown to promote fat loss in studies, but it’s not worth suffering from side effects for. If you’re main aim is to lose fat, you’ll be benefited more by a fat burner supplement.
For this reason. we advise you to avoid any supplements containing Yohimbe Extract.
Rauwolfia Vomitoria Extract
Let’s be honest, any ingredient containing the words ‘vomit’ don’t sound particularly appetising. And as it’s been commonly reported to cause side effects, it’s also on our ‘blacklist’ of ingredients to avoid too.
For this reason, we advise you to stay away from supplements containing Rauwolfia Vomitoria Extract – to stay safe.

It’s not good news when almost every ingredient inside a product can cause a side effect.
In case you skimmed through the section above, Caffeine added to proprietary blends can cause jittery side effects, Choline can cause your breath & sweat to smell fishy, while Yohimbe and Rauwolfia Vomitoria Extracts have shown to cause numerous side effects.

Dark Metal Thrasher Review Conclusion
We’ve reviewed hundreds of supplements, and we’ve never found an effective ‘hybrid’ product that does 2 things in 1.
Basically, Insane Labz have tried to make Dark Metal Thrasher a pre-workout/fat burner hybrid; they’ve clearly advertised this as ‘energy and weight loss’ enhancing product.
However, instead of helping to promote fat loss or improve your gym sessions, Dark Metal Thrasher is more likely to cause side effects.
For this reason, we can’t recommend this supplement, as there are plenty of better options on the market.
