The flavor is blueberry lemonade and I LOVE IT. It's so tart but sweet! It's 8oz of water with 1 scoop, so if it's too sour one can add more water and less scoop. It leaves a bit of an aftertaste + texture but it doesn't bother me. It mixes into water easily and has high quality ingredients. I don't have any side effects from it but it made my partner's chest hurt, even though it is stimulant free. I think some people are just more sensitive to pre-workout than others. Obviously stop use if there is this type of side effect. I think this two-part pre-workout set is a great value compared to other products in the same range. I'm extremely appreciative that there's stimulant free offerings. Review: Does the job without jittery caffeine - I’ve quit caffeine and feel much better. No anxiety, sleeplessness, hands shaking, just feel more at peace. So with that said I was looking for a pre workout that didn’t contain caffeine and I found this product. I haven’t had any side effects other than the initial tingly sensation on the skin feeling like pins and more than usual sweating but that went away after first use. Also there was this piece of shell fish or something stuck in my teeth! Yuck! Besides all that, you will feel this in 30 minutes or less ready to go. The blueberry tasted good but when you picture shell fish in this, it kind of kills the taste. Overall it does the job! ## Features - Crush Every Workout with JEKYLL: ProSupps Dr. JEKYLL Signature is a stim-free pre-workout powder designed to support strength, focus, and endurance with ZERO caffeine.

Subtler, lingering effects take a few hours to taper off. **Q: How is this vegan friendly if it contains milk?** A: Vegan friendly? I don’t think so. It even contains shellfish. **Q: Is the noolvl propriety component more or less nitric oxide? can we get some more clarity on what this compound is please?** A: NOOLVLTM COMMON NAME Inositol-enhanced Bonded Arginine Silicate TOP BENEFITS OF NOOLVLTM - Enhances processing speed and accuracy* - Supports executive function* - Boosts energy* - Promotes muscle performance* WHAT IS NOOLVLTM? nooLVLTM is comprised of two components: Bonded (inositol-stabilized) arginine silicate (Nitrosigine®) plus additional inositol. L-arginine has relatively low bioavailability (~20%) following an oral dose, so high doses are needed to significantly boost blood arginine levels.[1] Nitrosigine® and nooLVLTM have overcome this limitation by bonding the L-arginine to a silicate–inositol complex, which significantly enhances the bioavailability of L-arginine.[2–5] L-arginine is involved in promoting healthy circulation because it can be used for nitric oxide production. Blood flow to metabolically active tissues, like the brain and muscles, plays a big role in allowing these tissues to perform their functions at a high level. Bonded arginine silicate supports exercise performance and post-exercise recovery by promoting muscle blood flow.[6] It also supports brain performance, enhancing mental accuracy, focus, processing speed, and executive function.[5,7,8] nooLVLTM has been clinically studied in humans: It has boosted cognitive performance and energy in eSports athletes. nooLVLTM is an upgraded version of Nitrosigine®, an ingredient that supports blood arginine levels and nitric oxide production, enhanced energy, promoted focus and mental acuity, and supported better muscle response following exercise. nooLVLTM is a patented nutritional ingredient from Nutrition 21: It contains Nitrosigine® (l-arginine bonded to silica and inositol with affirmed GRAS) plus added inositol. nooLVLTM is gluten-free, vegan, and non-GMO. nooLVLTM is a trademark of Nutrition 21, LLC. NOOLVLTM DOSING PRINCIPLES AND RATIONALE Studied dose of nooLVLTM has been 1600 mg/day: Nitrosigine® has been 1500 mg/day. Since these are the highest doses that have been given in human research, we consider them to be the upper limit we’d be comfortable with for daily dosing. Since it’s possible that the product this is included in might be used more than once a day (i.e., a person could opt to take two servings), we included a half dose per serving (i.e., 800 mg of nooLVLTM). In Neurohacker’s subjective and objective internal N of 1 testing, the half dose of nooLVLTM had additive effects when combined with other nootropic ingredients.* NOOLVLTM KEY MECHANISMS Vascular function - L-arginine is the substrate for vascular nitric oxide (NO) production by NO synthase (NOS)[9] - Upregulates endothelial NOS (eNOS) [silicate][10] - Upregulates the blood levels of arginine, silicon, and NO[4] - Supports healthy vascular function [2] - Supports healthy blood pressure [arginine][11] [inositol][12,13] Brain function - Upregulates dopamine release[14–16]. - Regulates dopamine transporter (DAT) activity[17–20] - Supports neurotransmitter signaling [inositol][21] Cognitive function - Supports performance in complex cognitive tests requiring mental flexibility, processing speed and executive functioning[7] Exercise performance (ergogenic effects) - Supports exercise performance [arginine][22] - Delays time to exhaustion [arginine][22] - Delays muscle fatigue [arginine][23] - Supports muscle blood flow after exercise[6] - Protects from muscle damage after exercise and during recovery[6] ## Customer Reviews ### ⭐⭐⭐⭐⭐ best flavor ever, can't wait to try more *by R***S on February 16, 2026* This review is for the prosupps dr. jeckyll part cause I didnt try the mr. hyde yet.

No anxiety, sleeplessness, hands shaking, just feel more at peace. So with that said I was looking for a pre workout that didn’t contain caffeine and I found this product. I haven’t had any side effects other than the initial tingly sensation on the skin feeling like pins and more than usual sweating but that went away after first use.

The blueberry tasted good but when you picture shell fish in this, it kind of kills the taste. Overall it does the job! ### ⭐⭐⭐⭐ Be wary of the strawberry flavor *by S***. on June 14, 2024* I would like to start that I think the product, overall, is great. It gets me amped up and ready for the gym, just as it should, without going crazy on the caffeine since I prefer to remain stimulant free. I get GREAT workouts in, and the product is a great price. My only complaint is the strawberry flavor. It's not strawberry. Not even remotely close to strawberry. As someone who's favorite flavor is strawberry, this was a really off flavor if it's supposed to be strawberry. The mix is spicy. And not subtle. The spiciness caught me so off guard at first, that I legitimately thought I was allergic to the product. My throat started to feel really hot, and I was concerned for a moment until my husband took some of it too, and said it was also making his throat feel hot. So we looked at the ingredients list, and saw paprika was an ingredient and immediately it made sense. It tastes like paprika. My best way of comparing it is to imagine Tajin on the rim of a shot, and that's how it feels to take this. If you're someone who doesn't mind spicy or likes Mexican Candy shots, this is a good product. If you're someone like me who loves strawberry and bought this expecting it to taste sweet like a strawberry, then maybe avoid it or try another flavor. I'm going to give other flavors a try after I force myself to finish this one, but the strawberry IS NOT strawberry. ## Frequently Bought Together - PROSUPPS Dr. Jekyll Signature Pre Workout Powder with Creatine - Stim-Free Preworkout Supports Focus & Endurance - Caffeine-Free Gym & Fitness Supplements (Blueberry Lemonade, 30 Servings) - PROSUPPS Mr. Hyde Signature Pre Workout Powder with Creatine, Beta Alanine & Caffeine - Performance, Energy & Endurance - Clean Fitness & Gym Supplements for Men & Women (Blue Razz, 30 Servings) - PROSUPPS Mr. Hyde Max Pump Pre Workout Powder - Stim-Free Preworkout Supports Blood Flow, Muscle Volume & Endurance - Caffeine-Free Nitric Oxide Gym & Fitness Supplements (Blue Razz, 20 Servings) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/158337375-prosupps-dr-jekyll-signature-pre-workout-powder-with-creatine-stim](https://www.desertcart.sn/products/158337375-prosupps-dr-jekyll-signature-pre-workout-powder-with-creatine-stim) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-08*
