About The Product

Possessed is a pre-workout supplement made by Insane Labz. It costs $54.95 for 30 servings containers, and comes in 2 flavors – Gummy Worm and Strawberry Pena.

To determine how safe and effective Insane Labz Possessed is, we’ll analyze its 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 create a variety of products, but they definitely make more pre-workouts than any other supplements.

One thing that upsets us about Insane Labz’ products, is that they pack all of their ingredients into proprietary blends. But they’ve made a name for themselves as selling the ‘strongest’ pre-workouts available.

So let’s investigate further and see whether Insane Labz Possessed is worth buying or not.

Insane Labz Possessed Ingredients Explained

Insane Labz Possessed contains 9 ingredients overall, which isn’t a bad number to have in a pre-workout. However, one big problem we have is that every ingredient inside this Insane Labz Possessed is part of a proprietary blend (we’ll expand on this below).


Proprietary blends are mixtures of numerous ingredients that’re only shown to you as 1 quantity. As you can see from the ‘Possessed Blend’ on Insane Labz Possessed’s ingredient list, the overall amount is 1,100mg – but you’re not shown the dosages of each ingredient inside such as Caffeine Anhydrous.

This increases your risk of side effects, and also makes it uncertain whether this pre-workout will work. For this reason, we try to avoid any supplement that contains proprietary blends.

Anyway, now that you know why you should try to avoid proprietary blends, we’ll take you through each ingredient inside Insane Labz Possessed.

By the end of this review, you’ll know how exactly how safe and effective this pre-workout really is.


Here’s Everything You Need To Know:

Creatine Monohydrate 

Creatine Monohydrate is a key addition to any pre-workout, as it’s shown to enhance your strength and endurance.

In fact, it’s one of the most established compounds in the bodybuilding industry; everyone from normal gym-goers to bodybuilders consume Creatine Monohydrate, as it’s also one of the safest ingredients too.

However, we recommend that you consume at least 1,000mg Creatine Monohydrate per serving for it to work. The bad news is that this nutrient is part of a proprietary blend, so no-one knows the exact dosage inside Insane Labz Possessed.

For this reason, we can’t say for sure how effective Creatine Monohydrate really is. And it’s a great example of why companies should stop adding proprietary blends into their products.

L-Tyrosine & Citicoline

L-Tyrosine is a ‘brain booster’ that’s shown to enhance your cognition. However, while a boost in focus is beneficial, you don’t really need improvements to your memory in the gym.

We believe that L-Tyrosine is better suited to a nootropic supplement, but it can make a good ‘bonus’ addition to a pre-workout. We’ve grouped Citicoline here, as it’s also a ‘brain booster’ too.

The bottom line is that Caffeine Anhydrous boosts your focus enough to benefit your gym session, so these ‘brain booster’ ingredients aren’t necessary here.

Mucuna Pruriens & D-Aspartic Acid 

We’re not sure why Insane Labz have added Mucuna Pruriens into Possessed; it’s known for being able to raise your L-Dopa levels, which positively affects your testosterone levels.

However, studies have shown that you need to consume Mucuna Pruriens in 3-4 servings spread throughout your day, for it to work.

As you only consume pre-workout supplements once per day, there’s not much point in having Mucuna Pruriens here. We’ve grouped D-Aspartic Acid here too, as it’s also a T-Booster ingredient.

Ultimately, you don’t buy a pre-workout to try to raise your T levels – this is what testosterone booster supplements are for.



Beta-Alanine is quite a controversial addition to Insane Labz Possessed.

Why? Because it’s proven to enhance muscular endurance, but it also causes itchy and tingly skin (paresthesia).

Ultimately, people react to paresthesia differently; some people don’t mind it, while others prefer to avoid it.

Personally, we prefer to avoid tingly and itchy skin, as we find it very distracting and uncomfortable while lifting weights. But as Beta-Alanine is beneficial too, we’ll leave this up to personal preference.

Caffeine Anhydrous & Caffeine Citrate

In case you’re wondering, Caffeine Anhydrous is the best stimulant you can find you can find in supplements.

Why? Because it’s a pure form of Caffeine (Anhydrous simply means that Caffeine has been dehydrated into powder form, so it can be added into supplements).

Ultimately, this means you can keep track of how much you’re consuming – unless Caffeine Anhydrous is added into a proprietary blend, like it has with Insane Labz Possessed.

As it’s inside a proprietary blend here, you’re not given the exact dosage of Caffeine Anhydrous here; putting you at risk from jittery side effects.

Your risk of these side effects is increased, due to containing Caffeine Citrate too – which is another form of Caffeine.

Personally, we wouldn’t take the risk of consuming an unknown quantity of Caffeine – to stay safe.

Choline Bitartrate 

If you want to know about a useless ingredient that causes a side effect, Choline Bitartrate is what you’re looking for…

Choline Bitartrate has shown to cause your breath and sweat to smell fishy, and hasn’t shown to deliver any benefits to improve your gym session.

For this reason, it’s one of the ingredients that we prefer not to consume as part of a pre-workout supplement. Not a good addition to Insane Labz Possessed at all.

Juniper Berry

This is the same Juniper Berry that you add to gin and tonic; it’s known for containing antioxidants, which are great for your general health, but it’s not shown to improve your gym sessions.

Ultimately, this is nothing more than a good ‘bonus’ ingredient here. But we would have preferred to see a key pre-workout nutrient such as Citrulline Malate instead (which is proven to enhance your muscle pumps in the gym).

Side Effects

The bad news is that Insane Labz Possessed has the potential to cause numerous side effects; this is the inevitable risk of adding every ingredient into a proprietary blend.

But even without the proprietary blend issue, Insane Labz Possessed contains numerous ingredients reported to cause side effects; Beta-Alanine, Choline Bitartrate and Caffeine Anhydrous in unknown quantities.

Here’s the potential side effects of taking Insane Labz Possessed: 

  • Itchy and Tingly Skin (Beta-Alanine)
  • Fishy breath and sweath (Choline)
  • Jitters (Unknown amount of Caffeine)
  • Energy Crashes (Unknown amount of Caffeine)

Insane Labz Possessed Review Conclusion

Ultimately, you can’t ignore that every ingredient inside Insane Labz Possessed is part of a proprietary blend; this increases your risk of side effects, especially as it contains 2 sources of Caffeine and Beta-Alanine.

We can’t stress enough that companies need to stop using proprietary blends. There’s simply no benefit to the customer, and it puts them at risk from side effects.

For this reason, we can’t recommend this pre-workout to you. We believe that you could spend your money much better by looking elsewhere.
