Perfect for Body Recomp
I love my pre workout 🏋🏻 I’ve been using Transparent Labs Lean Pre-Workout for a few weeks now, and I’m honestly impressed. If your goal is body recomposition (building lean muscle while cutting fat), this formula is a great fit. Down 20 pounds First, the energy is smooth and steady. no crash afterward. The caffeine level feels just right, especially if you train early in the morning or after a long day. Second, I love how transparent the label is (true to the name). No proprietary blends, no hidden ingredients, you know exactly what you’re putting in your body. The focus and mental clarity during workouts are noticeable. I feel locked in, especially during strength training sessions. It also mixes well with no clumps, and the flavor is clean not overly sweet or artificial tasting like many other pre-workouts. Worth every penny.

Less tingling, more balanced boost than other brands
Good taste. It's on the pricey side, but doesn't give me the aggressive skin tingling that other preworkouts give. Other options I've tried make me sweat immediately and tingle all over. It feels like a more relaxed and firm energy boost than getting hit with a freight train.

Getting the pump without the jitters
This is one of the cleanest pre-workouts I’ve tried. The flavor is nice and I appreciate that there are no artificial sweeteners. It mixes easily and gives a smooth boost of energy and focus, no jitters, just steady pump through my workout. The taste is a bit on the bitter side, but not a dealbreaker. If you want a pre-workout gets you through your workout, this one’s a solid pick

Good preworkout supplement
Good product and flavor. It can hurt your stomach if you just start taking it, so make sure you ease into it. It's hard to judge the effectiveness of preworkout supplements but it does feel like I'm not as tired at the end of a wStevie. My only problem is I wish they had a flavor without stevia. Overall it's a good preworkout that boosts my energy level during and after workous.

Pleasantly surprised by both flavor and effectiveness
First, I was pleasantly surprised by the flavor. Some of the reviews here had me dreading it, but I've tried both strawberry lemonade and blue raspberry, and can happily report that they're both decent. It's about the flavor you'd expect if Monster Energy made a strawberry lemonade or blue raspberry flavor....not something you'd drink for fun, but if you can handle Monster, this will taste fine. As for effectiveness, I bought both Lean and Stim-Free, and both of them make an immediate and noticeable difference. I can't yet comment on long term gains, but what I can say is: After taking Lean for just a week, I added two reps for both pull-ups and bench press, and that's after being stuck on a plateau for bench for the past few weeks. I was also massively more energetic during my initial warmup. I also took Stim-Free before a morning jog. I noticed a clear tingling sensation in my face and chest, which is one of the potential side effects associated with greater bloodflow. I'm not a very good runner and usually get lactic acid pain pretty quickly, but during this run, there was no lactic acid at all, which is one of the main benefits that Stim-Free claims. I felt purely limited by how hard I was breathing and not by muscle pain. One week in and I'm already a clear five stars. I'll check back in once I have evidence of long term gains.

Lots of energy
I love love this product. I use this pre workout every morning and half of the same amount for recovery. Does not give me jitters or that hard crash. Dissolves easily and the taste is so good. Keeps my energy level throughout my workout and the best part I have never had any stomach discomfort.

Update: … the flavor..
Update: Taste: poor Effectiveness: medium Side effects: miserable I’ve been using for about a month. I’m stopping using this preworkout. At first the flavor was awful then it got better as I figured a mix of scoops and water I could tolerate. Since then my stomach has been meeesed up! I thought maybe it was some other stuff in my diet. Got off of it a few days then went back to it and boom messed up tummy all over again. Do not recomend. Got it today, couldn’t wait to try it since I ran out of my usual. Kicks in quick, lasts for the workout, but man.. it does not taste great.. got the strawberry lemonade. Has a crazy after taste that hangs about a minute. Could be the natural sweeteners. Maybe more or less water with the suggested scoop. I’ll update later if I find a combo that works ok. Lower doses compared to what my normal pre workout had, so we will see how I like it going forward.
