Beach Bum
Thavage Pre-Workout in Beach Bum flavor absolutely delivers! The tropical flavor is smooth and refreshing—not too sweet or overpowering, which is rare for a pre-workout. It mixes easily with water and goes down great even early in the morning.The energy boost kicks in within 20–30 minutes and hits hard without the jitters. Focus, endurance, and pumps are all noticeably enhanced, and best of all—there’s no crash afterward. I felt locked in throughout my entire workout and didn’t feel drained after.

Genuine Surprise
First time trying this. From what I’ve seen Chris Bumstead uses his own products so I figured “why not?” Dissolves easy. Tastes smooth and has the flavor as advertised (1 or 2 scoops). It’s a bit more expensive then what I am used too. I’m used to jittery tingling feelings in my preworkout. I confess, I was let down (AT FIRST) because it didn’t feel like I was getting the bang for my buck. Then I started my workout and kept going, and going, and GOING. Cardio, weights, and even off days. I felt like I could push my limits without questioning if my heart was going to explode. It was seamless energy. Highly recommend and worth the money.

A MUST HAVE!
Recently picked up Chris’s Secret Stuff and it is my GO-TO! If you are an intermediate lifter or more experienced, I would suggest double scooping for more caffeine and pump. Overall, great formula for a focused and sustainable lift. Tastes great too!

Not the pre-workout I was hoping for
I have been lifting weights consistently for the past 15 years, and in this time, have tried numerous different brands of pre-workout. I wanted to try this brand and line of pre-workout because I had heard great things and know the pedigree that is associated with its creator. But I was unfortunately disappointed in it. I'm about 3/4 of the way through the tub, so I can safely say I have adequately given it its fair chance to impress me. The flavor is fantastic, don't get me wrong in that. The pump it gives you during the workout and the longevity to keep pushing through more reps and sets compared to your baseline are both absolutely fantastic. But when I think of a pre-workout, I want something that primes and readys me for a lift, and unfortunately this particular supplement is not that. It takes a very long while to even feel the initial effects, and they are pretty minimal in terms of getting you ready for a workout; so not very ideal for just a quick lift, but rather a much longer session where the anti-fatigue affects will really help you out toward the end. If that "priming" you for a lift is what you are looking for, I would try another brand.

Great preworkout
I’ve tried many flavors of this brand and all have been great. The Beach Bum flavor wasn’t my favorite, it was a little salty, but overall I’d highly recommend this brand.
