Transparent Labs BULK vs Pre JYM – what’s the best pre-workout supplement?

Today we’re going to look at these two popular, premium products to try and get to the bottom of which is best. We’ll outline each, their benefits, and how they compare across a range of different factors.

Pre-Workout – What to Look For

pre jym vs bulk

The main role of a pre-workout is to support better workouts and, usually, counteract tiredness and protect you against fatigue.

This makes it a great choice for busy working days before workouts, or early workouts. This is why pre-workout is such a popular supplement choice – that and the fact it usually makes workouts feel great (1).

There are a few different categories we’re going to use to discuss these two competing pre workout supplements and what they can do for you:

  • Improving workout performance: strength, power, endurance, and/or hypertrophy
  • Improving fatigue-management and protecting you from exhaustion
  • Boosting the quality of nutrient uptake and/or use in exercise
  • Protecting muscles and other tissues from the worst impacts of workout-stress
  • Supporting recovery after the workout
  • Logistics like value-for-money and price per serving

The better a pre-workout performs in each of these categories, the better it is likely to be.

Obviously, effectiveness is our number one choice, but then other factors like cost, value, taste, and the design focus of a product are important.

We want a pre-workout to do what it says, and not side-step the most important functions when we review it.

Transparent Labs Bulk Pre Workout

transparent labs preseries bulk vs pre jym

Transparent Labs’ BULK Pre-workout is a workout enhancing supplement with a focus on supporting recovery and weight gain.

It’s a way of stimulating more growth through better workouts and then immediately supporting better post-workout recovery. In this way, BULK indirectly supports weight gain quality in two – overlapping – ways.

BULK is one of the best products on the market for these purposes with a major benefit to both sides of a workout.

Ingredients: What’s In Transparent Labs BULK?

  • Caffeine: both anhydrous and DiCaffeine Malate
  • A vitamin blend: B6, B12, and D3
  • Mineral blend: Sodium, potassium, zinc, and boron
  • Citrulline
  • Beta-alanine
  • BCAAs
  • Betaine anhydrous
  • Mental support amines: taurine, L-tyrosine, and L-tryptophan
  • Alpha-GPC
  • Astragin – an absorption booster

Transparent Labs Bulk: Benefits

These break down into 3 major benefits that you’re going to want to focus on.

First, better workouts come from better mental and neuromuscular performance. Caffeine, anti-fatigue amines, and alpha-GPC combat fatigue.

This leaves you with improved mental performance, power output, and strength-endurance throughout your workout.

Second, you’re going to have better muscular metabolism and chemistry.

The BCAAs protect you against muscle damage, while the improved muscular metabolism from caffeine and betaine supports both endurance and the delivery of nutrients to muscles after workouts.

Finally, there’s an overlap between these two groups for post-workout recovery. By improving both of these factors, you’ll see significant recovery benefits.

BCAAs protect and signal for muscle growth, improved betaine blood flow supports the required nutrient and energy availability for better quality weight gain: more muscle growth.

Pros

  • Great synergies
  • Better workout-specific mental performance benefits
  • Better value for money
  • No conflict between caffeine and creatine
  • Two types of caffeine for better results

Cons

  • Lacks acetylcholine synergy that is in Pre Jym

Pre JYM Pre Workout

PreJym is the Jym all-purpose pre-workout supplement to support better workout performance. It’s a focused pre workout supplement with a good blend of ingredients and a premium overall design.

PreJym doesn’t define itself as a weight-gain pre-workout supplement like BULK does, and offers a more general approach.

There is still some overlap, however, with a focus on improving workouts with the same muscle metabolism, mental performance, and recovery combination.

Ingredients: What’s In PreJym Pre-Workout?

  • Creatine
  • Beta-alanine
  • Betaine
  • Taurine
  • A-GPC
  • Huperzine
  • Citrulline
  • Beet root extract
  • BCAA
  • Piperine

Pre JYM Benefits

bulk vs pre jym

Like BULK, PreJym’s main benefits are improving wakefulness and the performance of workouts in 3 major ways: muscle metabolism, mental performance, and post-workout recovery.

First, creatine, caffeine, and citrulline are going to have large benefits to workout performance.

The combination of caffeine and creatine doesn’t work as well as independently, but these are powerful compounds in clinically-effective doses in any case.

The mental performance benefits are interesting. PreJym has less fatigue-resilience benefits compared to BULK, but has better acetylcholine-boosting benefits from Huperzine and Alpha-GPC (a powerful synergistic pair).

This makes it good for overall mental performance but not as effective for workout-specific fatigue-protection.

Finally, this product has a shadow of post-workout recovery benefits. These are mostly due to the combination of creatine, citrulline, and betaine.

These improve muscle energetics while also supporting the uptake of nutrient-rich blood in the muscles after exercise.

This means better recovery for improvements to your next workout, as well as improving muscle building.

Pros

  • Great green apple flavor
  • Excellent Acetylcholine synergies
  • Good all-rounder for pre-workout supplements

Cons

  • Worse value for money
  • Inferior caffeine profile
  • Lacks some of the best fatigue- and mood-adjusting amines from BULK

Transparent Labs BULK Vs Pre JYM: Our Verdict

When comparing Transparent Labs BULK vs Pre Jym, Transparent Labs BULK is the better pre-workout supplement. It has a clearer idea of what it wants to do, and has a smart overall design that makes the most of each scoop with powerful synergists for a range of workout and recovery benefits.

It’s also better value for money than PreJym.

The design of Transparent Labs BULK and PreJym are actually quite similar.

They both support workout performance, muscular recovery, and mental health support. They take different routes to similar results and have an interesting blend of ingredients.

Why is Transparent Labs BULK The Best Pre-Workout?

While both of these supplements have similar actions, the benefits of BULK’s synergies in each area are powerful:

  1. Mental support from the combination of taurine, tyrosine, and tryptophan with Alpha-GPC
  2. Muscle metabolism and chemistry regulation from caffeine, BCAAs, betaine, and electrolytes
  3. Better strength-endurance from caffeine, betaine, B-alanine, and citrulline

These make BULK one of the most effective pre-workout supplements for weight gain and recovery.

This makes it a great way to target more muscle-building stimulus and the recovery processes that make it happen.

In this way, BULK is not only a great product, but also has a more clear target. It’s a weight-gain pre-workout that does what it says.

Meanwhile, Jym is effective but lacks the clear design direction to compete, which does let it down a little in our comparison.

It also helps that the BULK value for money is a little better, while Jym is a notoriously premium-price manufacturer.

We will say, however, they make this up relatively well with their excellent flavors – especially green apple.

Conclusion: Our Final Thoughts

pre workout

Overall, we prefer Transparent Labs BULK to PreJym. The long story short is that it does all the same things, has slightly better synergies, and offers a more cause-and-effect design for its stated goal. 

It’s also a great choice for 3rd party tested supplements with a guarantee that it has no contaminants or unwanted heavy metals.

This makes BULK a great pre-workout supplement to support better overall performance, but specifically the high-quality weight gain that gives it its name. If you’re looking for the best in class, BULK might be it.

PreJym is still a great product and, if you’re looking for something a bit more general, it could be a great choice to make up the creatine you’re not taking. 

Creatine and caffeine do have some negative interactions for absorption, but it’s a good way to take the concern out of a whole supplement stack.
