Pre JYM High-Performance Pre-Workout

Take it 30 to 45 minutes before you train, so the energy and focus are there when the workout starts.* Customers describe it holding through the whole workout and winding down without a crash.

Both. It’s made for adults who train, and a good formula doesn’t change with how long you’ve been lifting. Everyone starts the same way: half a scoop or less the first time, to see how you handle it.

Mix one scoop in 16 to 24 oz of water and drink it 30 to 45 minutes before you train. The first time, use half a scoop or less to see how you tolerate it. After that, never take more than one scoop, and don’t take it within six hours of bedtime.

300mg per scoop, about the same as three cups of coffee. Don’t use it with any other caffeinated product, and that includes coffee and energy drinks. Too much caffeine can cause nervousness, irritability, sleeplessness, or a rapid heartbeat.

Then go with Pre JYM Stim-Free. The label says not to use this one if you’re sensitive to caffeine. Stim-Free has the same active ingredients at the same doses, minus the caffeine, including 6g of citrulline malate, 6g of BCAAs, 2g of creatine HCl, 2g of beta-alanine, and 1.5g of betaine.

Don’t use Pre JYM if you’re under 18, pregnant or nursing, sensitive to caffeine, taking any prescription or over-the-counter medication, or have a known or suspected medical condition. Stop taking it two weeks before any surgery, and keep it out of reach of children. If you have any adverse reaction, discontinue it immediately and see your doctor. It’s made on shared equipment that also makes products that may contain egg, milk, soy, and tree nuts. Check with a healthcare professional before you start, as you should with any supplement.

It can if you take it late, so don’t take it within six hours of bedtime. If you train in the evening, Pre JYM Stim-Free has the same active ingredients without the caffeine.

Some people feel a mild tingle and plenty feel nothing at all. As one reviewer put it: “No tingling, no crash.” That tingle is a common, temporary sensation from beta-alanine, which Pre JYM has at 2g per scoop.

Some long-time customers say one scoop keeps working for them. As one reviewer five years in put it: “I’ve never felt the need to up my dosage.” Either way, never take more than one scoop.

Because Pre JYM is built to support the muscles doing the work. Creatine helps your muscles regenerate ATP, the energy molecule they burn through during hard sets.* Leucine, one of the three BCAAs, helps switch on muscle protein synthesis, the process that repairs and builds muscle.* That’s why every scoop has 2g of creatine HCl and 6g of BCAAs.

Look at what’s in the scoop. Every scoop of Pre JYM has about 21g of active ingredients, each at the dose printed on the label, including 6g of citrulline malate, 6g of BCAAs, and 2g of creatine HCl. Put that label next to whatever you’re comparing it with.

Every active ingredient is printed with its exact amount, so you can check each one against the research yourself. Hiding doses behind a blend name is like handing you a workout that says bench press, flies, and curls with no sets and reps. We print the sets and reps.

It’s when a label groups ingredients under a blend name, like an energy matrix or a pump blend, and prints one total weight for the whole blend instead of each ingredient’s dose. The ingredients are listed from most to least, but you can’t see how much of each one you’re getting. That’s how a label can name a long list of ingredients while giving you very little of most of them.
