Not kidding the peach mango tastes like juice. I’m VERY picky when it comes to texture with things like pre-workout and this does not have a chalky texture AT ALL!!! I usually mix in 1 scoop with ~12 oz of water and no problems dissolving either. I also have to say this has the all the optimal ingredient levels at an AMAZING price. Also doesn’t have a bunch of crap in it that doesn’t do anything like a lot of the more expensive ones. Also even though caffeine is the thing that helps the most with workouts I honestly love that this doesn’t have it because they often put way too much and this you can control the amount of caffeine you have by supplementing with something else. Perfect all around – and way better than more expensive pres.

I recently tried the PRE-SF non-stimulant pre-workout, and overall, I’m quite impressed, rating it a solid four out of five stars. The best part about this product is the excellent value it offers. It’s reasonably priced and delivers noticeable benefits. I appreciate how easily it mixes with water, ensuring a hassle-free preparation process. However, I did experience some minor stomach discomfort after using it, which is why I couldn’t give it a full five stars. If you’re looking for an affordable and effective non-stimulant pre-workout option, PRE-SF is worth a try, but be mindful of your stomach’s sensitivity. No jitters and it felt like I was on speed.

Very scary experience using this product. I had taken it pre-workout for a week or so. I had a powerful skin tingling sensation but I read that that was normal. This morning the skin tingling was even more pronounced and happened suddenly. My vision started to blur and I was getting sleepy, thankfully I pulled the car over and call my wife. I lost consciousness on the phone with her and a couple more times after that and wound up in the ER. I have never passed out in my life, I am fit and don’t have any medical conditions. I was perfectly fine once this poison was flushed from my system. Also, it tastes horrible. Zero stars.

Proper dosage, good quality, decent flavor, and best of all cheap! May not be the flashiest, but it is definitely one of the best.

This is an excellent stim free pre workout for the price. It checks all the boxes for ingredient dosing. I definitely notice concentration and output improvements. Will this make you feel unstoppable like a preworkout that has 300mg of caffeine? No. But it will give you the drive to crank out a few more reps and recover quicker between sets. So it’s perfect for me.
I was concerned about the pink lemonade flavor after reading other reviews but personally I think it tastes great and is much better than 90% of the pre workouts I’ve had in the past 15 years. I saw another reviewer complain of headaches from this and I can tell you with pre workouts packing this much in a scoop it’s easy to get dehydrated so make sure to drink a lot of water around the time you take it. I’ll be ordering this again over transparent labs stim free preworkout as the ingredients are similar and this one is almost half the cost.
Formula changes, keep in mind. –
For the price this stuff is the very best! Only maybe gorilla mode is better but much more expensive. Works Amazingly. The flavor could be a little better but the pink lemonade is still amazing!

Edit to original review from January 6, 2024:
I have changed my position on the removal of betaine from the formulation. After doing an updated review of the research, it would appear that betaine is not effective for any performance enhancement, especially if one is already taking/using creatine monohydrate in the recommended dose of 3-5 grams per day.
In fact, after reviewing the more recent research, betaine in higher doses of 4g and above actually appears to increase blood cholesterol, specifically LDL cholesterol, by 12-14mg/dL, which is quite notable.
Thus, after learning of this new evidence, I am changing my negative that I gave the original review regarding betaine removal. I have also changed the following paragraphs that discussed betaine to reflect this updated position.
I now rate this 4.5 stars which is an upgrade from my previous 4 stars.
*********************
I’ll start by saying that this is an all-around decent stim free pre-workout. There have been some slight formula tweaks in the past few months that new buyers should be aware of so they can make the most informed decision.
When I originally bought this product back in the summer of ’23 the formula contained betaine anhydrous and theobromine. The new formulations no longer have these ingredients. I couldn’t care less about the theobromine as that’s not reliably been shown in research to increase performance by any metric I’d consider meaningful. The removal of betaine I am now indifferent towards/slightly in favor of (as of my edit on 2/15/24>, given the recent evidence on the supplement not having much effect for any performance benefits at all, and likely increasing blood cholesterol (specifically LDL) by 12-14mg/dL at higher doses of 4g and above. The original formula I believe only has 1.25-1.5g of betaine.
There were 2 changes with this reformulation with regard to dosing B vitamins. 1) folate is now folic acid, and 2) increased the dose of vitamin B6 to 4,412% of daily value from what was a more reasonable 3,530% of daily value. This change in folate also increased the dose of folic acid from 300 dietary folate equivalents (DFE) to 510 DFE. Not that folate or the B vitamins have much impact on performance in the presence of a well rounded diet, but the switch to folic acid is superior.
All in all, the changes aren’t likely to be massive with respect to the effects on exercise performance.
I also think the flavor is good and can be watered down or concentrated to fit one’s preferences.
I would eventually love to see an NSF certified for sport or Informed choice/informed for sport 3rd party testing for banned substances. While this has a cGMP seal on the label the additional consumer protection from contamination would be nice.
I think a 4.5 start rating is pretty fair for the reasons given above. The dosing of the other ingredients is in line with research and the value is rather good such as L-citrulline being 6 grams. 5 star rating would include getting a 3rd party certificate seal for banned substance testing from informed sport/informed choice or NSF sport.
TL;DR: they removed betaine (indifferent/possible positive – see edit above), removed theobromine (indifferent to), increased the vitamin B6 dose (indifferent), and increased folate dose and use folic acid now (positive). No caffeine and great taste make this a go to for later day workouts.

This product definitely gave a good boost. However, it is way too sweet for me.
