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.Edit: Results after one year!Long term, I found that this stuff makes the biggest difference for running. The citrulline malate and beta alanine are incredible for running, especially if you're like me and usually limited by lactic acid. After a lifetime of struggling to run more than 3 miles, I ran my first full marathon last year! The only way I can describe it is legitimately life changing.On the lifting side, I think the main benefit for lifting was honestly the caffeine in the Bulk version (plus taking creatine, which is not in this supplement). If you're only lifting and not running, consider saving some money by just trying some caffeine + theanine pills.I also tried a DIY approach to further save money: on Amazon, I bought generic citrulline malate and beta alanine powders, along with caffeine pills and some flavor powder. I can happily report that the DIY preworkout works just as well as this product but for less than half the price!

Works great and is a clean product product
Iโve 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 youโre 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. Iโm 59 years old and do hiit and metabolic conditioning style training. Iโm a big proponent of kettlebell which I have been doing for over a year now. When those workouts get intense, Iโm 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, itโs just what I do and works for me. So if you like stim free, do the subscribe and save which I recommend.

Start with a low dose.
One of the best pre-workouts I have seen in the market. Works well for me. Better to start with a half of spoon dose. Taste is not bad. Kept me energized throughout my workout. Even after two hours I felt energized. A little expensive tbh. Mix well with water.

Definitely worth it
Tingles for sure, but subsided after consistent use. They felt like a little shot of the adrenaline needed to power through a hard workout. Tastes great and digests easily. No after effects at all. Definitely buying this again!

Essential for my late day exercises
A friend of mine recommended Transparent Labs to me many years ago and I've been using them since.Due to time constraints, I only have time to workout in the afternoon/evening time. After finding out that there are "stim free" preworkouts, I decided to try out Transparent Labs' stim free preworkout.I'm usually pretty tired (and lazy) after I get off work, to the point that I don't want to exercise. However, this definitely helps get me through my late day workouts. It's almost like drinking a satisfying cup of coffee without the downside of taking caffeine late in the day. Also, I've never tried regular preworkouts, so I have no comparison of how "good" of a pump this gives. But I can definitely lift more and longer than without taking the stim free preworkout.As far as flavor goes, I've only tried Blue Raspberry, strawberry lemonade, and orange; with strawberry lemonade being the best so far.

More Energy & Strength
As someone who works out later in the day pre-workout always kept me up at night. First time Iโve tried this and after 30 minutes felt the results. There is a slight tingling in the muscles and I had an extra boost of both energy and strength throughout my hour long workout session. More so than Iโve had on other products and was able to sleep with no issues. I will be buying again!

Very ineffective and disappointing
This is a product that does not taste very good, does not mix well, very gritty and bitter, there is no positive effect of this product, did not enhance my workout experience, the effectiveness was non existent, no energy gain, very expensive for a placebo effect, that didnโt even give me a mental help.

Perfect for late-day workouts! Great pump without the jitters
"I work in construction during the day and train right after work. I was looking for a caffeine-free pre-workout because I didn't want it to affect my sleep, and this product has worked incredibly well. It helps me maintain my performance in the gym without feeling jittery or anxious. The ingredients are high quality and the dosages are fully transparent. Very satisfied with this purchase!"
