Dr. JEKYLL Signature V2 Pre-Workout: Benefits, Ingredients, and Review

Not every great workout starts with a surge of caffeine. For those who train late at night, are sensitive to stimulants, or simply prefer to fuel their body without the buzz, finding a pre-workout that truly delivers can be a challenge. Enter Dr. JEKYLL Signature V2 by ProSupps USA.

ProSupps Dr. JEKYLL Signature V2 is a non-stim pre-workout supplement designed to promote sharp focus and muscle endurance with ZERO caffeine. With a new look and improved formula, this upgraded version promises to be the ultimate training companion for anyone who wants performance without stimulants. But can a caffeine-free pre-workout really pack the punch you need? Let’s find out.

What Is Dr. JEKYLL Signature V2 Pre-Workout?

Dr. Jekyll Signature is a pre-workout designed to boost strength, focus and endurance, with ZERO caffeine. It is developed with trusted ingredients to support men, women, and athletes from all fitness levels.

Dr. Jekyll Signature is the ultimate stim-free, pump-inducing pre-workout. This formula combines an unrivaled nitric oxide response blend known as the Performance Matrix, with a Cognitive Drive Matrix for focus and training intensity. In addition, Dr. Jekyll Signature includes an Adaptogenic Matrix featuring Ashwagandha and thermogenic ingredients to help lower cortisol levels and increase metabolic rate, completely stim-free.

Think of it as the other half of the ProSupps pre-workout duo. While Mr. HYDE Signature V2 is the high-energy, caffeine-powered beast, Dr. JEKYLL Signature V2 is the calculated, clean-performance counterpart that works without a single milligram of stimulant.

Ingredients Breakdown

Just like its sibling product, the Dr. JEKYLL Signature V2 is built on full transparency. The fully transparent formula features Beta-Alanine, Creatine, nooLVL (inositol-enhanced arginine silicate), Choline, and L-Tyrosine plus thermogenic-enhancing ingredients to support muscle endurance, pumps, focus, and training intensity. Here’s what’s inside:

Beta-Alanine (3.2g)

The Performance Matrix includes Beta-Alanine (3.2g) to boost endurance, strength, and blood flow. Beta-Alanine is a well-researched amino acid known for its ability to buffer lactic acid buildup in muscles, allowing you to push harder and longer during intense sets. The 3.2g dose is a clinically studied amount that sits right within the effective range. As with any Beta-Alanine product, you may experience a mild tingling sensation (paresthesia), which is completely harmless.

Creatine HCl (1.5g)

Creatine is included for maximum power. Creatine HCl (1.5g) is part of the Performance Matrix designed to boost endurance and strength. Creatine HCl (Hydrochloride) is a more soluble form of creatine, meaning it absorbs efficiently and is easier on the stomach compared to traditional creatine monohydrate. It supports ATP regeneration for explosive power and strength output.

nooLVL (Inositol-Enhanced Arginine Silicate) (800mg)

800mg of nooLVL enhances and optimizes blood flow for improved muscle pumps, nutrient delivery, and endurance. ProSupps is the first to introduce nooLVL, a pump and focus combined super-compound, that is designed to power blood flow and energy for sustained workouts. This is a standout ingredient that differentiates Dr. JEKYLL from many competing stim-free pre-workouts, addressing both the pump and cognitive focus aspects in a single compound.

Choline Bitartrate & L-Tyrosine

Choline and L-Tyrosine help you stay locked-in. The Cognitive Drive Matrix features Choline Bitartrate and Panax Ginseng Extract, helping you maintain mental clarity and focus during every session. L-Tyrosine is a precursor to key neurotransmitters like dopamine and norepinephrine, which play a critical role in motivation and mental sharpness. Together, these ingredients form the backbone of Dr. JEKYLL’s focus-enhancing capabilities.

Ashwagandha (KSM-66) & CaloriBurn GP

With Ashwagandha and Grains of Paradise, the Adaptogenic Matrix supports stress reduction and promotes fat utilisation. Ashwagandha (specifically the KSM-66 extract standardized to 5% withanolides at 125mg) is a powerful adaptogen backed by numerous studies showing its ability to reduce cortisol, improve recovery, and support overall well-being. CaloriBurn GP (Aframomum melegueta at 30mg) is a thermogenic ingredient derived from Grains of Paradise that can help increase metabolic activity and promote sweating during training. Some users may experience a warming sensation and increased sweating after use, which is attributed to Aframomum melegueta.

Additional Ingredients

The formula is rounded out with Panax Ginseng Extract for cognitive support, Black Pepper Extract (BioPerine) for enhanced nutrient absorption, and other supporting ingredients. The product is zero sugar, zero carbs, zero calories, and gluten free.

Formula Transparency and Certification

One of the standout features of the Dr. JEKYLL Signature V2 is its commitment to quality assurance. Dr. Jekyll Signature proudly carries the Informed-Choice certification badge. Informed-Choice is a globally recognized third-party quality assurance program for nutritional supplements. Products that carry the Informed-Choice logo undergo rigorous routine testing and manufacturing audits and have been tested for more than 220 banned substances prohibited in sports by LGC’s world-class anti-doping labs.

Made in the USA, soy- and gluten-free, with no fillers, no banned substances, and no artificial dyes. Every ProSupps product undergoes rigorous third-party testing for purity, efficacy, and transparency, every batch, every time.

This certification is a major confidence booster for competitive athletes who are subject to anti-doping regulations and need absolute assurance that their supplements won’t cause a positive test.

How to Use It

Mix 1 scoop of Dr. JEKYLL Signature Stimulant-Free with 8 oz of cold water. Consume 15 to 30 minutes before exercise.

If you decide to stack with another pre-workout, such as Mr. HYDE Signature, assess your tolerance with half a scoop of each before proceeding to a full serving. Shake container well before use.

One of the great advantages of a stimulant-free formula is that there are no restrictions on timing. Whether you are hitting the gym late at night, or just not a fan of caffeine, Dr. Jekyll Signature has you covered. Unlike stimulant-based pre-workouts that should be avoided within 4 hours of bedtime, you can take Dr. JEKYLL at any hour without worrying about disrupted sleep.

The Stacking Advantage

A unique feature of the Dr. JEKYLL Signature V2 is its ability to be stacked with its counterpart, Mr. HYDE Signature V2. Mr. Hyde Signature and Dr. Jekyll Signature were designed to perform individually and work as a stack. By combining both, you harness the power of extreme energy and focus with enhanced pumps and training capacity. ProSupps recommends assessing your tolerance if you decide to stack the two products by starting with half a scoop of each before proceeding to a full serving.

This stacking approach gives users incredible flexibility. On days when you need a full-throttle energy boost, stack them. On late-night sessions or recovery days, use Dr. JEKYLL solo. It’s the best of both worlds.

Taste and Mixability

The V2 is available in several popular flavors including Blue Razz, Blueberry Lemonade, Sour Candy, Strawberry, and Orange. The Blueberry Lemonade flavor is described as delicious and refreshing, making it a treat to sip on before hitting the gym.

User feedback on taste is generally positive, though slightly mixed. Many users say the taste is truly great, and it mixes and dissolves well. Others describe the stimulant-free formula as having the same punch as before, with flavoring that is fantastic as always. However, opinions on taste are mixed; while some enjoy it, others find it too sweet or chalky and difficult to mix. As with most supplement powders, taste preference is highly subjective, and adjusting water volume can help find your sweet spot.

Performance and Real-World Results

User experience with Dr. JEKYLL Signature is overwhelmingly positive, especially among its target audience of nighttime trainers and caffeine-sensitive individuals.

Positive feedback: Customers generally appreciate Dr. Jekyll Signature for its effectiveness and quality. Many users report a significant boost in energy, focus, and mood during workouts without the jitters or sleepless nights associated with caffeine. The product is praised for delivering excellent pumps and maintaining muscle fullness.

One reviewer noted surprising results for a pre-workout with no caffeine, reporting excellent focus and pump that lasts a full hour to an hour and a half workout, with no tingles or jitters.

Users who work out at night report that caffeine messes with their sleep too much, but with Dr. Jekyll they still get the extra energy to power through workouts after a long day, while still getting the benefits of beta-alanine and the other ingredients.

Another user described a very strong physical and mental boost, saying it will make you go.

Critical feedback: Not everyone is blown away. One user felt the product didn’t provide enough pep for a pre-workout and suggested stacking it with something else, as they traditionally look for an all-in-one pre. Another noted the flavor is a little intense but it doesn’t take away from the results. A small number of users felt that without caffeine, the product simply couldn’t match the raw intensity of a stimulant-based formula.

Overall, customers gave Dr. JEKYLL Signature an outstanding rating on ProSupps’ own site. On Amazon, the product holds strong ratings based on thousands of individual reviews.

Value for Money

The product is priced at approximately $24.97 for a 30-serving container. At well under a dollar per serving, this represents outstanding value for a caffeine-free pre-workout with clinically dosed, transparently labeled ingredients and Informed-Choice certification.

When you consider that many competing stimulant-free pre-workouts charge significantly more for fewer active ingredients or proprietary blends, Dr. JEKYLL Signature V2 offers remarkable bang for your buck. And if you choose to stack it with Mr. HYDE Signature V2, the combined cost is still competitive with many single-product premium pre-workouts on the market.
