Probably the best I've ever had
Taste is amazing. Mixes fast and easily. No jitters and no crash. I am thoroughly impressed with how well this got me moving, how good I felt while doing it and was really successful at the gym when I train this out. Highly recommend

    Gonna try to give an honest review. I've taken a few pre works but I try to use them as little as possible. But now that im using them for the gym and to stay awake on night shift after the gym , im looking for something different.

    With that being said I liked that it didn't give me jitters quite as bad as other brands. Other brands dang near give me panick attacks! This one did not. It increased my energy and focus but didn't spike it! Which i like. It also lasted from 6:30pm to 4:30 am. Kind of like coasting energy which I loved. But…. ITS NASTY AF !!! And I mean that. It tastes AWFUL. But because it's clean and natural i will figure out a way to ingest it without it making me wanna puke. 🫠

    Kick It Up Some

    I’ve used a number of pre workouts before. I come from the time of the original Hydroxycut (before they changed the formula). I can tell you Bulk is very similar in feeling to that from so long ago with just one scoop. I did as directed and went half then .75 then full. Every single time I know exactly when it’s kicking in. PLEASE, before you start this make sure you are healthy enough to use it. Talk to someone about your concerns. I’m telling you this because it’s gonna make you sweat and feel like you need to move. Be cautious. But 10/10 would recommend.

    Sour Gummy is bomb, no chemical taste and great effect!

    Pretty much the 1st time you take it's ALOT, esp if you haven't taken pre workout in a while..

    I got the Sour Gummy flavor and its surprisingly VERY good in taste and effect, I HATE the chemical taste of some of the other major brands and this just tastes like Waterboy/electrolyte power type of drink.

    Very smooth and I love the nerds gummies and tastes similar to that to a degree but not overwhelming.

    Overall it lasts 2 hrs+ depending on tolerance Id cycle it on and off to keep the effect consistent.

    No stomach issues, nothing crazy I've seen just a SLIGHT jitter/itchy/tingles on the 1st day but again afterwards nothing like that just focus, energy, great pump and a smooth ride.

    So I purchased sour gummy due to the reviews. And the flavor is like you squeezed 15 lemons into your cup, nothing about it is sweet like nerd clusters. But the first two times i took it i did go over my max PR at the gym.

    I will update it after using for a week.

    Sour Gummy = 4 year expired cough medicine

    I have no idea hour “Sour Gummy” got approved by quality control. There is absolutely nothing Sour or Gummy about it. I can’t imagine a group of folks testing flavors.. tasting it and thinking “This is delicious; ship it!”

    Imagine yourself as a child and your grandmother has 4 year expired cough medicine; that’s what they should have called this flavor.

    It’s a shame because normally Transparent Labs have great products.
