Pre Jym 2.0 Review


Pre Jym 2.0 Review / 29th November 2017

T2. Aliens. Big Momma's House 2.

Pre Jim 2.0 reviewAll represent rare instances of sequels which don't suck.

Ok. Maybe not that last one.

But when we're talking supplements, sequels are usually a poor imitation of the original, thrown together when an ingredient gets flagged up or questioned.

Which brings us to Pre Jym 2.0, the brand new preworkout from Dr. Jim Stoppani.

Now, the original Pre Jym formula was great. I'd go as far as to call it one of my favourite preworkouts of all time. But how about it's successor?

Today's Pre Jym 2.0 review will give you the straight-up facts on whether this sequel joins the ranks of the elite, or belongs in the bargain basement. As usual, my deliberately harsh supplement rating system will pull no punches.

Not So 2.0

In case you don't keep up to date with fitness industry shenanigans, Jim Stoppani broke off his contract with (the sole retailer of his Jm Supplement Science line) last year, and partnered with GNC.

I discussed this in my recent Pro Jym review, so give that a read if you want a catch up.

There was a dispute as to who owned the original Jym brand, so for a brief period we had the doctor formulating new Jym products under his GNC deal while BB continued selling the original line-up after removing images of the doc from the tubs.

Crazy, right?

Of course, this didn't last very long.

By mid 2017, Jym had reunited with and the old line-up of products have now been discontinued completely.

So if you were hoping to bag some of the Pre Jym original formula, you're out of luck.

But under the new deal, the Jym supplement line-up is no longer exclusive to the one marketplace, as he continues to work alongside GNC and a host of other well established retailers.


Pre Jym 2.0 Review

The above information is a very important thing to know when trying Pre Jym 2.0...

Because despite the name change and the snazzy new label design, what we see here is an almost identical formula to the original.

While the  2.0 suggests a "next generation" of Jym supplements, this is merely clever marketing.

Once we get under the hood of the product, what we are really getting is the same old same old, with the name merely altered to separate this product - and proclaim superiority - from confusion with the old Jym brand.

This product was formulated purely to enable Jym to continue his brand after splitting from, and the formula reflects that.

In fact, the only notable difference between the two formulas is the inclusion of huperzine-A in the new blend.

Huperzine-A is a nootropic alkaloid which is added to bodybuilding supplements to increase mental focus, although no significant research exists to document it's effectiveness at doing so. It has, however, been shown to increase muscle contraction force, so that's something. (1)

Is huperzine-A going to make or break your workout? Absolutely not.

Thankfully, the rest of the Pre Jym 2.0 formula still stands up, meaning it is able to hold it's own at the top end of the premium preworkout supplement market:

  • 2g creatine HCL
  • 6g citrulline malate
  • 2g beta-alanine
  • 3g leucine
  • 300mg caffeine

Let's take a quick look at the key players inside Pre Jym 2.0 to determine what you can expect from using the product and, more important, whether the dosage of each ingredient is enough to give you the results it claims on the tub...

That second point is crucial.

You see, the preworkout marketplace is rife with below-par products which hide their formula behind bogus proprietary blends or under-dose key ingredients, leaving you feeling ripped off.

For the most part, you should be pleasantly surprised by Pre Jym.

  • 300mg caffeine

Caffeine is the key player in any great preworkout, and Pre Jym doesn't skimp on the dosage here.

The effectiveness of caffeine is dependent upon an individual's tolerance levels, but 300mg per serving puts this right at the top end of the preworkout spectrum and means that this product is most certainly a one-scooper, unless you plan on laying in bed like a human pneumatic drill. (2)

Most people know caffeine for it's energy boosting properties, which have been well documented in various studies over the years, but it's also been shown to boost mental focus and is often touted as a fat burning ingredient to boot.

The fat burning benefits are overstated, but the mental boost and energy kick are more than enough to warrant it's position as a valuable preworkout ingredient.

  • 6g citrulline malate

Citrulline malate is the most under-appreciated ingredient in a truly great preworkout supplement.

While we like to focus on the ingredients we can feel working (caffeine and beta-alanine), citrulline gets to work in the background and when supplemented regularly can make a huge difference to the quality of your overall training!

Six grams is the clinically proven dosage at which we can expect to see the maximum response, so Pre Jym 2.0 hits the mark here.

This post will tell you more about citrulline malate.

If you'd like to enjoy a greater pump during your workout, faster recovery between sets and better endurance, citrulline is the way to go. (3, 4)

  • 2g beta-alanine

Have you ever felt your face tingling after drinking a preworkout?

That's beta-alanine.

But while it's often unfairly used as a superficial ingredient which is thrown in purely so you can 'feel' your pre kicking in, there are numerous benefits to using beta-alanine.

A 2010 study from researchers at the University of Manchester discovered that boxers increased their punching power by as much as 2000% during the closing stages of a bout via supplementing with beta-alanine prior to training. (5)

Beta-alanine is useful for improving our ability to push through "the burn" during training, with another useful study showing us that subjects were able to force out 25% more repetitions per set. (6) 

At 2 grams per serving, the dosage here hits the nail on the head in terms of performance benefits.

The Final Verdict

There will primarily be two groups of people looking at Pre Jym 2.0.

Those looking for a great preworkout, and those trying to figure out if they should switch to this formula from the old Pre Jym supplement.

If you fall into the first group, you will find Pre Jym 2.0 to be a great preworkout supplement. I'm a big fan of the doctor and the work he has done in the supplement industry over the years. This product lives up to it's billing.

In true Jim Stoppani style, it's dosages have been clinically proven for increased workout performance and the label is very transparent - no hidden proprietary blends or suspect ingredients.

It deserves it's place at the top of the preworkout marketplace.

If you're a current Pre Jym user, you are really not missing anything "new and improved" here other than maybe the packaging. If you like green.

As such, Pre Jym 2.0 receives a very hard to achieve 4 star rating from my deliberately harsh supplement rating system. The fabled "5 stars" is lost due to the fact that I'm still a bit pissed the name hinted at a new and improved formula.

Order Pre Jym 2.0 from here for the best deal.
