Benefits of PreSeries Bulk Pre-Workout

It is hard to know where to begin with an excellent product like this because there are so many high-quality ingredients in its formula.

One of the most immediate benefits of using Bulk Pre-Workout is that it’s BCAA content will help to stimulate muscle protein synthesis.

This is particularly important while you are training because it helps to offset the potentially catabolic effects of breaking down muscle tissue during intense workouts. This reduces muscle wasting and help you to make progress more rapidly.

Citrulline Malate is another fantastic ingredient to use while you train as it acts as a precursor to nitric oxide production. This helps to stimulate your circulatory system, enhancing workflow and increasing the delivery of nutrients into your muscle tissues.

This also helps to give you at pumps, causing further damage to the muscle tissues and triggering a phenomenon known as cell swelling which has been linked to increased muscle hypertrophy.

Beta Alanine helps to attenuate lactic acid accumulation in the muscles, and reducing acidity like this help you to crank out extra reps while also reducing the buildup of waste in your muscles.

Aside from the physical benefits, it provides a range of different stimulants such as Caffeine Anhydrous, L-Theanine, and Choline Bitartrate, all of which help enhance concentration and focus so that you can have great workout even after a long day at work.

What’s more, PreSeries Bulk contains Black Pepper Fruit extract which helps to further stimulate the circulatory system and enhance the absorption and subsequent uptake of nutrients.

As if all that wasn’t enough, the Testosterone Support complex contains Vitamin D3, Zinc, and Boron, helping to jack up your hormonal production and accelerate your gains even further.

Are There Any Precautions?

Always follow the usage guidelines provided by the manufacturer on any supplement you purchase and always speak with your doctor before taking supplements.

PreSeries Bulk promotes stimulatory effects and contains caffeine so please exercise caution prior to use if you are particularly sensitive to caffeine or other stimulants.

Because of its vasodilatory effects, it should be avoided by anyone who has ever suffered a heart attack or other form of cardiovascular disease.

PreSeries Bulk Pre-Workout Review


One thing that I think really sets Transparent Labs Bulk Pre-Workout apart from a locked of comparable pre-workout supplements is that all of the ingredients it contains are provided in effective dosages.

I have lost count of the number of supplements I’ve seen that use “proprietary blends,” which basically means that you have no idea exactly how much of each ingredient you are receiving, leaving you unable to say whether or not you are actually receiving an effective dose.

That is definitely not the case with Transparent Labs Bulk Pre-Workout.

This product contains highly effective ingredients which are backed by science and provided in quantities that really work.


The fact that Transparent Labs Bulk Pre-Workout is available as a powder means that you can very easily leave it in a shaker and add some water to it when you are ready to head to the gym.

This makes it incredibly convenient for those of you who work in a busy office and don’t want to take entire tubs of supplements with you; simply throw a scoop into your shaker before you leave home in the morning and it will be ready to go before you leave the office.

Taste / Composition / Mixability

Blue Raspberry is a good choice of flavor because it is most impossible to get it wrong.

Transparent Labs Bulk Pre-Workout has a great taste to it and seems to mix very easily into water, leaving you with a light translucent drink that you will look forward to chugging down on all of your training days.

There are some supplements containing BCAA which leave a layer floating on the surface due to poor mixability, but Bulk Pre-Workout has been instantized very effectively so that this isn’t an issue.

There are 3 other delicious flavors to try as well: Orange, Sour Grape and Strawberry Lemonade!

Is it Worth the Money?


I would go so far as to say that the Transparent Labs Pre-Workout supplements are some of the most cost-effective on the market, largely because of the very generous dosages of each ingredient that they contain.

You’ll find no gimmicky ingredients or deceptive proprietary blends in this product, so you can rest assured you are getting excellent value for money.

Final Verdict

There are countless pre-workout supplement on the market that simply do not cut it, but I have to say I am impressed by Transparent Labs Bulk Pre-Workout.

This product delivers the goods in terms of quality, quantity, taste, effectiveness, and of course value for money, so if you are in the market for a pre-workout supplement that you can depend upon then I would very strongly recommend checking this one out.
