  • Amazing for POTS!!
Flavor Name: Tropical Punch
I have POTS and struggle with staying hydrated and not getting light headed during workouts. I’ve tried a few stim free pre workouts but felt like I’d drank nothing at all. This pre workout is hands down the best I’ve ever taken. I actually feel a difference without getting shakey, cold, clammy and ultimately light headed and out of it. I’ve had the best workouts lately and it’s because of this. I actually sweat in the best way now making me feel like I’ve gotten in a great workout. Start with a tad less then a scoop and prepare for a lil itchy skin but other then that amazing! ... show more

  • Pleasantly surprised by both flavor and effectiveness
Flavor Name: Strawberry Lemonade
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. ... show more

  • Transparent Labs Stands Behind Their Products
Flavor Name: Strawberry Lemonade
I had a minor issue with my order, and the customer service team at Transparent Labs was quick to respond and resolve it. David followed up personally and sent a replacement without any hassle. He clearly explained the tracking process and made it easy to get updates if needed. It’s rare to find a company that stands behind their products and service this well. I really appreciate the transparency and responsiveness. By the way, the product is great. Highly recommended! ... show more

  • Good Solution for Non-Stim Preworkout
Flavor Name: Strawberry Lemonade
Good solution for non-stim pre workout. I am recovering from a TBI and have been looking for a performance booster that doesn’t involve 3,000mg of caffeine and taurine. You will notice itching with this, particularly if you haven’t had pre or non-stim before. It mixes well with water or other elements, and I felt an incremental increase in muscle access during workouts. ... show more

  • Do not waste your money
Flavor Name: Strawberry Lemonade
Absolute trash. Felt like I’ve been ripped off after taking this trash. I’ve been in the gym over 20+ years and have taken many pre-workout supplements and this one is one of the worst. Taking a whole scoop made me nauseous and ended having a bad workout and left the gym. Took a half scoop the next day and could have went to bed. There’s no happy medium and it clearly does not work. Still have a full can that’s just collecting dust as I bought this back in February ... show more

  • Taste Actually Makes Me Shiver
Flavor Name: Strawberry Lemonade
I've been testing out different pre workout brands for a while, and I've yet to find one that has good ingredients and tastes good at the same time. And if you couldn't tell by the title, this only checked one of those boxes... First off, the ingredients and macros are amazing. While it doesn't have caffeine, this brand is great if you're trying not to intake junk ingredients. The only thing keeping this from a 5 star review is the taste... At first, it seems nice as it tastes like strawberries and cream, but as the days go by, it really grows on you. It quite literally makes me shiver and sometimes gag. As for in the gym, it's relatively "ok". I haven't noticed any improvements since I've started using it (1 month ago), but that's most likely due to the supplements I've taken before. If you never had pre-workout before, this should be pretty effective, but be aware of the itchiness from the beta-alanine. On money, I'd say it's pretty good. Compared to other brand like Genius, this is a lot better value for money, even if it tastes a bit worse. Overall, PLEASE double check what flavor you're getting and if you truly want it. I've only had the Peach Mango and the Strawberry Lemonade, and from my experience, please don't go for them. ... show more

  • Improved workout
Flavor Name: Tropical Punch
This works well for me. I can definitely feel a difference in my workout. I'm able to get a couple extra reps in with less rest between sets. Also helps me focus. I didn't experience any of the side affects listed by others (nausea, tingling, etc..), however, because I tend to have a hard time getting enough sleep, I only use 1/2 the dose and limit my coffee intake to 1/2 cup in the morning before workout. I use the Tropical Punch flavor and it tastes better than I was expecting. Can't comment on other flavors. It does have Stevia, which I personally don't care for, but I don't notice it in this brand/flavor, but again, I only use 1/2 dose. In the end, everybody's different so you just have to take all the reviews with a grain of salt and try stuff to see if it works for you. TL is kind of on the expensive end and it would be nice if they didn't include natural flavors, but on the balance I'm happy with it and will continue to use it. I'd recommend to others. ... show more
