Overview of Gold Star Performance Products New Jack
Gold Star Performance Products has a multitude of products that they are behind. Their lines consists of test boosters, PCTs, fat burners, commodities and two different pre-workout supplements: Triple X and New Jack.
New Jack is a pre-workout which sells the benefit of 50mg of Ephedra in it; however it is known that the “good” ephedra is no longer legal to sell in the US. Overall New Jack lacks many of the components we liked about Gold Star’s Triple X pre-workout. With a prop blend dominated by under-dosed ingredients we cannot recommend this pre-workout over Triple X. We’re a fan of Triple X. Not so much of New Jack.
Testing Results and Ratings
We reviewed Gold Star Performance Products New Jack on five categories. We first start by looking at it’s ingredient profile. This portion of the review looks at the different ingredients used in the pre-workout, what their intention is and how effectively dosed are each ingredient.
We then look at effectiveness. An effective pre-workout will use high quality, proven ingredients, at clinically backed dosages. This is generally an extension of the profile section. The higher quality ingredients used at proper dosages, the more effective that product will be.
Then we move into the taste of the different flavors we’ve tried. We grade each flavor separately and average the scores for their overall taste rating. We were able to test out the following flavors: Sour Cherry.
Mixability refers to how well the powder mixes in 12oz of water. We use the shaker bottle test. This would be your typical Blender Bottle with the spiral chrome ball.
Finally, we talk about value. Value is the combination of profile, effectiveness, taste and mixability in relation to cost. Another part of value are the competitors and other versions of pre-workout products on the market.
If you’ve been to our website before you know that we are not fans of proprietary blended supplements. I believe as the consumer we deserve the right to an open label. Unfortunately, New Jack is another prop blended pre-workout on the market. Companies will say they do this to “protect” their formula but with enough education and 3rd-party testing, you can find out anything. With that said, let’s dive into this profile.
One area we do like is the use of DiCaffeine Malate at 404mgs (providing 300mg of caffeine). DiCaffeine Malate, per TigerFitness.com, provides less of a crash than you would get wth Caffeine Anhydrous. Another common benefit is that DiCaffeine Malate doesn’t provide that sudden rush of energy, but a slower energizing feeling that lasts throughout a lift.
L-Taurine, increases muscle endurance and strength, is included in this pre-workout at 750mgs. I’ve seen this as high as 2g before in a pre-workout. Another transparent portion of the label is L-Tyrosine, increases focus, at 300mgs, but this is under-dosed as well. Again, I’ve seen this dosed in the 2g area.
The area that disturbs me is the prop blend of New Jack. It contains 6,520mgs of 8 different ingredients. The first is L-Cittruline, helps with the pump. I know that clinical dosage of L-Cittruline is 6g. That would practically take up this entire prop blend if it was clincally dosed. We can then make the educated guess that it is not properly dosed. They follow it up with Agmatine Sulfate, another pump enhancer. I’ve seen this typically dosed between 500mg-1g. This could be properly dosed, but no-way to tell based on the label.
Moving on we run into the ever-so-popular pre-workout ingredient Beta-Alanine, maximizes strength output. This is clinically dosed at 3.2g. This is third on the ingredient list so it’s a safe assumption that it is not clinically dosed. I’ve seen this between 2 and 3.2g in pre-workouts on the market.
Dendrobium Alkaloids help with your overall cognitive functions and helps improves your mood. There is not enough evidence to suggest that there is a proper dosage amount, but I do like the use of the ingredient as I am a big fan of cognitive enhancing ingredients. The next ingredient is Rauwolfia Vomitoria Extract, which also can enhance your mood. Another good ingredient we find in a lot of products on the market.
We get into 2-Amino-5-Methylhexane which is a form of DMHA. I am a fan of DMHA. In fact, I like DMHA compared to DMAA. However, not knowing the dosage hurts. We know it is higher than 50mg (the label claims 50mg of Ephedra and that’s the next ingredient). DMAA is typically dosed around 75-80mg while DMHA is around 150mg. The 2-Amino-5 variation of DMHA is said to be stronger, so less than 150mg is fine, but I don’t know if it is much higher than 50mg of Ephedra.
Speaking of Ephedra, it is important to note that Ephedrine Alkaloids are illegal. This is not the same Ephedra in this product. For those of you that had wishful thinking, think again. Now that is not to say there are not positives to Ephedra Extract, there are, they just aren’t even close to the fat loss capabilities that Ephedrine Alkaloids gave. The last ingredient is Synephrine which has been shown to increase energy, but this would be a very low dosage.
Overall, some of the ingredients are nice selections, but they are being overshadowed by the under-dosed main ingredients of L-Cittruline, Agamatine and Beta-Alanine.
When you wake up at 5am and hit the gym you want something that works. For me, unfortunately, New Jack didn’t provide the type of energy, pump and focus I would look for from a pre-workout. You would think given that the two first ingredients in the prop blend were pump ingredients you would have a great pump, but I didn’t. I found myself using additive pump products to get it. I was disappointed here because I enjoyed Triple X from Gold Star Performance Products. This, to me, was a let down compared to that. I would urge you to check out the review we did on Triple X.
With the mood enhancers and cognitive function enhancers I thought I would have laser focus and I just didn’t either. I will admit, I am a stim head, but this product should still deliver something to me.
The taste of New Jack was one of the better features of this pre-workout. Unfortunately I do not buy products based on taste; I buy them based on effectiveness. With that said, if you’re a fan of cherry you are going to love this.
New Jack didn’t have any issues with mixability. The powder is very fine. At 8g a serving it is pretty small compared to a lot of the other pre-workouts, so it makes it easier to mix it up in a little amount of water.
There is a $50 price tag on New Jack on Goldstar’s official website. I cannot justify that cost for this pre-workout when the ones on our Best Pre-Workout Supplements list (click here to see it) all retail for less than that. If you are looking for a good tasting pre-workout and want to spend this kind of money, go ahead. I cannot give it my stamp of approval at this time. If they properly dosed the pre-workout then they would have a much better argument to sell this for $50.
