Excellent Stim-Free Pre-Workout, But Powder Is Very Fine
Overall, this is a very solid stim-free pre-workout from Transparent Labs. The formula is clean, effective, and delivers great pumps and endurance without any caffeine or jitters. It mixes well, tastes good, and I really appreciate knowing exactly what I’m putting into my body. That said, the powder is extremely fine. When scooping it out, it tends to puff up into the air, and if you’re not careful it’s easy to inhale some of it. Not a dealbreaker, but definitely something to be mindful of. Despite that minor issue, it performs exactly as advertised and is one of the better stim-free options I’ve used. Just scoop carefully.

Works great and is a clean product product
I’ve been using transparent labs products for over a year now a little pricey, but worth it if you train regularly. Awesome, clean an effective product. If you want to bulk up you will get that pump if you’re leaning out like I am to have a more athletic look, works great but of course with any product you take, nutrition is 90% the battle. You will get the tingling effect for a few seconds, but goes away quickly. I’m 59 years old and do hiit and metabolic conditioning style training. I’m a big proponent of kettlebell which I have been doing for over a year now. When those workouts get intense, I’m able to push through and go a little further, which is great for those heavy days if you will. Basically stim free does the job when it comes to pump and energy to get the job done. I do recommend cycling off after you finish your tub for about 7 to 10 days, it’s just what I do and works for me. So if you like stim free, do the subscribe and save which I recommend.

No Caffeine but comes on STRONG
I wasn't expecting much from a caffeine-free no stim pre-workout this stuff comes on strong energy, "tingle," no buzz I've seen reviews complaining of the taste, I purchased the Tropical Punch, nothing wrong with the taste but if you're used to sweet sweet Kool Aid and strong sugary flavors be prepared to be disappointed, it's a mild fruit taste, not too sweet ... is it a little grainy, yeah ... it's not a dessert, it's a pre-workout mix, I'm giving it five stars for doing what it's supposed to do and tasting/mixing way better than I expected Takeaway, the taste is not unpleasant, and if you want it thoroughly dissolved use a blender and warmer water, I use cold water and hand mixer, a little grainy, not too sweet, not overpowering flavor, gives good energy lasts a long time

Good energy, focus, no side effects
It’s a good product considering it’s a non stim pre. Taste is really sweet and strong but that’s kind of expected, it was not a problem for me. It didn’t make my stomach upset, no headaches or pre workout crash. It does cause a tingling sensation but I don’t really mind it. I also take it whenever I need a pick me up to focus at work, since I don’t drink caffeine. It does help me focus. I don’t have it everyday so I feel like it’s a good value for the money. It helps my workouts for sure but it’s not as powerful as regular pres.

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.

Works great
This stuff is great, no jitters or weird feeling of getting too much caffeine, but this stuff helps give me a great workout, I can definitely feel a big difference.

Terrible reaction
I had an awful experience with this pre-workout. Shortly after taking it, I became extremely sick — vomiting, diarrhea, intense stomach upset, and an uncomfortable hot, itchy feeling. I felt so unwell that I couldn’t even work out and ended up feeling sick for the rest of the day. I’ve used other pre-workouts before and never had a reaction like this. Unfortunately, this was completely unusable for me and not something I would ever recommend.
