Transparent Labs Stim-Free Pre-Workout - 30 Servings, Blue Raspberry

I wanted to completely cut caffeine from my diet. Even though the pre-workout I was taking before was helping me lift, it was starting to affect my body due to the caffeine levels. This stim free option is perfect. It still gives that itch feeling that makes you want to throw around weight but you have 0 caffeine related issues. I’ve been focused, increasing reps/weight and enjoyed the blue raspberry flavor. I’ve also noticed I’ve been sleeping WAY better because it is stim free and I lift in the evenings. This is my new go to pre-workout.

This pre workout is the stim-free, pump-delivering formula I’ve been looking for! After ordering a couple different brands and having bad luck (powder either came rock solid inside the container or just didn’t deliver), I decided to spend a couple extra dollars than what I budgeted for this one. Boy am I glad I did! My volume for my workouts is rapidly improving without feeling like I’m draining myself too fast. The clean ingredients is what really does it I think. My only complaint is the amount of foam produced when shaken with water, and that some settling occurs when mixing, but those aren’t my top tier value points anyhow. It works, it works well, and it’s not too much more money than the average.

I've been looking for a stim free pre workout for a while, and this one checks almost all the boxes. My only real complaint is the flavor. It could be better, it tastes a bit sour but not in the good way lol. Performance wise, this is the best stim free pre workout I've tried. My lifts feel strong and my runs feel sustained.

Just amazing really. No stimulants. Works like a bomb. Tastes great too. Transparent labs has now quickly become my fav brand. Hope they keep it clean.

I’ve been using this for over a month and it’s become my go-to pre-workout for afternoon/evening sessions. I train most days and take one scoop ~20–30 minutes before lifting. Main benefit is no caffeine but still noticeable performance support—better endurance and improved workout quality without affecting sleep. I originally chose Transparent Labs because the ingredients are independently verified and fully disclosed. That matters to me, even if it costs more. I’ve also tried Nutricost’s stim-free version. It’s cheaper, but I prefer the taste of this one and trust the ingredient quality more. Downside is price, but I ended up putting it on subscription to save a bit since I use it regularly. If you want a clean, caffeine-free pre-workout you can use consistently, this has worked really well for me.

Very good hits hard fast flavor is very strong one thing to note though is the beta alanine causes an intense itching or burning on the skin for the first few minutes it’s not something that’s wrong with the product that’s just what it does overall really good product

As someone who doesn’t do great with caffeine, this is a great alternative that still makes me want to get up and feel energized. Taste is good too and easy to get down.

Some of the claims are partly true, but they are written in a marketing tone. Here is the straight truth: 1. Betaine (BetaPure) True that betaine is found in beets and grains. True that some studies show it may help with exercise performance and small increases in muscle output. The big claims like “many other aspects of health” are marketing, not proven. 2. Citrulline Malate Yes, citrulline increases nitric oxide and blood flow. Yes, 8 grams is a common “effective” dose for pumps and endurance. The term “best nitric oxide booster” is opinion, not proven fact. It helps performance, but not as dramatically as ads make it sound. 3. Beta-Alanine This one is solid. It is proven to raise carnosine levels and delay fatigue in high intensity exercise. The tingling feeling is normal. So this claim is mostly true, but results vary. 4. elevATP This is the weakest claim. It is a patented blend with a couple small studies behind it. Some evidence shows a slight increase in ATP output, but the changes are small and not life-changing. So “quicker recovery” and “improved performance” are stretch claims. Bottom line • Beta-alanine and citrulline have strong support. • Betaine has some support but not as strong. • elevATP has limited evidence and is mostly marketing.
