Met Rx Creatine 4200 Review: An in Depth Analysis of the Supplement

With almost every creatine supplement out of the thousands available offering 5g per serving, why do MET Rx buck the trend and only give you 4.2g?

In our MET Rx creatine review, you're going to learn two things you didn't know.

Firstly, if you think you're taking 5g of powder, chances are you're not. Secondly, appearances can be deceiving—a capsule may be large, but that doesn't mean that it's a challenge to swallow.

Ingredients And Nutrition Facts

As you may have already guessed with the help of some rather descriptive branding, one serving of this supplements gets you a 4200 mg dose (or 4.2g) of HPLC pure monohydrate.



Serving Size


Best Taken



6 capsules



Anyone reading this article can see that 4.2g is below the frequently recommended 5g dosage, but does it really matter?

Well, as much as I like to use science to answer questions, I don't think this one requires any investigation — 4200mg is a perfectly acceptable amount. In fact, it's not just fair, it might be ideal.

You want to know a little secret about creatine? The same creatine that you've used in the past

When you're adding a scoop of creatine to your shake or drink, there's a high chance that the powder does not equal five grams. I actually put this to the test on myself, for my own curiosity, and because I had a weighing scale handy.

All I did was take a level scoop of powder and place it in the bottom of my shaker bottle, which was already on the weighing scale. In fact, I actually weighed the powder on two different scales, because, well I had two scales so why not?

I found that the creatine I thought weighed 5g actually weighed 3. Was I mad?

No, not at all. In the grand scheme of things, a gram here or a gram there is going to have little to no effect on anything, let alone any bodily changes that the human eye can detect. It's for this reason that you shouldn't panic at MEt Rx's slightly lower than average dosage.

Benefits And Effectiveness

Because these fairly large pills are easy to swallow, they're convenient for everyday use, and especially for those who have on-the-go lifestyles or who travel. You don't have to spend time finding a suitable drink to mix your powder into, you can just take them whenever you feel like it.

More on the size of the pills later.

Being pure HPLC monohydrate, you can be sure that your muscles are getting a big boost, especially regarding strength and power. As for how much strength you can expect to gain, this is best illustrated using an example.

A meta-analysis, which basically pools together loads of relevant studies, found that for the bench press, an improvement in 1rm from between 3% to a whopping 45% is achievable.

As you might expect, if you've been bench pressing religiously every Monday for the past decade, you will not be getting a 45% increase in bench press strength. But even as little as 3% strength gains should not be sniffed at, especially if you're already pressing decent weight.

That said if you're a total newbie, expect a nice bump in strength from taking these creatine capsules. As for when to take them, I recommended waiting until after training. We'll look into creatine timing a little later in this review.

Sizes And Servings

Met Rx boasts an impressive 240 capsules per bottle. That certainly sounds like a lot, but as you can see on the label, you don't get anywhere near 240 servings, not even close.

Per bottle, you get 40 servings which for the price, is actually a good deal. Especially considering it will last you well over a month.

For one serving, take 6 capsules. Yeah, that's quite a lot of tablets, and it might be too many for some of you, which brings me onto my next point...

Capsule Size

I won't sugar coat it, the capsules are quite big. Surely, this makes them a nightmare to swallow, and you should just buy a powder instead?

Not quite. While the caps are undeniably large in size, they are deceptively easy to swallow. They are capsules rather than pills, and the coating is really smooth and not hardened like a typical supplement pill.

This makes the 6 capsules a (you guessed it) a much easier pill to swallow...literally.

How And When To take

As I mentioned earlier, I recommend taking creatine 4200 after training, and after pushing your body hard so it can really benefit from the supplement.

If you want to know the nitty gritty usage details, take them with either a post-workout protein shake or wait until you get home and have them with a nice cooked meal.

There's no need to slam them down as soon as you re-rack the barbell for the last time, you're body is still receptive to creatine regardless of when you take it.

Overall Review

Overall, MET Rx Creatine 4200 is one of the best creatine capsule supplements on the market. It strikes the perfect balance between quality and affordability, in which you don't have to pay a lot for a simple product.

With creatine 4200, there's no second guessing how much creatine you're getting, as each of the 6 easy-to-swallow capsules gives you a grand total of 4200 mg of HPLC monohydrate. While it would be the icing on the cake to see more sizing options, buying an extra bottle is a quick and easy fix.

I hope you enjoyed our MET Rx Creatine 4200 review. Hopefully, it helped to clear up anything you were unsure about.
