They’re calling it a “Scientifically Advanced All-In-One Formula for Improved Workouts.” It’s Pre JYM from Jim Stoppani of JYM Supplement Science. If you haven’t heard of him, he’s a scientist who’s been working out since he was 11 years old. He’s got a website, he was a Senior Science Editor at Muscle and Fitness Magazine, and he works with Bodybuilding.com, and he’s basically pretty serious about what it takes to perform, succeed, and excel. He runs his company very closely, even taking questions directly come customers through Twitter and Facebook.

Pre JYM Ingredients and How They Work

Pre JYM is a comprehensive pre workout supplement, and in some cases, comprehensive can mean that there are lots of different ingredients for lots of different benefits, but the amounts of each ingredient are so small as to not really have any effect in the end. This is something that Pre JYM, and JYM Supplement Science, pushes back against pretty hard. This supplement uses full, effective dosing for all of its ingredients, and no proprietary blends. Everything is fully disclosed.

The formula is divided up into several matrices:

• The Power/Strength Matrix includes Creatine and Beta Alanine which both increase the strength and power of your muscles for more intense lifting.
• The Maximal Pump/Vascularity & Energy Amplifier includes Citrulline Malate which will increase the amount of nitric oxide in your system, opening up your blood vessels and allowing increased blood to make it to your muscles for that pump you want.
• The Fatigue Fighting Anabolic Activator includes BCAAs L-Leucine, L-Isoleucine, and L-Valine to ensure a quick and complete post workout recovery. If you can’t go back to the gym the next day, then you need BCAAs.
• The Focus & Drive Intensifier uses Caffeine and Huperzine A to increase energy and mental clarity and focus so your eyes stay on the prize and you have the energy, will, and stamina to see it through.

Frequently Asked Questions We Get

Does it have any side effects?

After pouring through countless customer reviews, it looks like the most common we’ve seen is instance of bloating, a strong “tingly” feeling, and insomnia.  Obviously you can prevent the insomnia issue by taking it as early as possible in the day before your workout, but that’s not always possible for many who have a late day workout routine.

Is there a Pre Jym pre workout available without caffeine?

At this time no, however, the owner has explicitly stated that there is a caffeine free version of the product available called Post JYM (which is a post workout supplement).

How do I take it?

The instructions on the label say to mix one scoop of Pre JYM with 14 oz of water about 30-45 minutes prior to your workout.  It’s not stated whether or not you should take it on an empty or full stomach, however, it is recommended that you start with half a scoop to assess your tolerance.

What are the reviews saying?

Check out a couple of popular Pre JYM reviews we found on Youtube:

Where to Buy

Pre JYM is sold through bodybuilding.com. The 20 serving tub sells for $35.  It doesn’t appear to be sold on Amazon, and currently no brick and mortar stores like CVS, Walgreens, or Walmart carry it.

Conclusion

With a well rounded formula, fully dosed ingredients, and rave reviews, I would say go for Pre JYM, with just a couple reservations. 300 mg of caffeine is a lot, so some people might find that to be too much. Also, the price is a little steep, but not too awfully bad. If the big dose of caffeine doesn’t bother you, give Pre JYM a try.

User Questions and Answers

Hi , I was wondering if there are any ingredients in this pre workout that can worsen existing gynecomastia. Also could any ingridients in Pre Kaged or ErgoBlast worsen gyno? Thanks in advance. -Floyd

It doesn't look like it to me, but I don't know all the ins and outs of gyno. You should check the ingredients with your doctor.- Rob
