What Makes Demolish Different?

Demolish Pre-Workout by Frenzy Labz is formulated with high doses of both traditional and “exotic” stimulants.

The formula lists everything clearly, including 6g L-citrulline (pump), 3.2g beta alanine (endurance/tingles), 1.5g glycerol monostearate (hydration, but often causes clumping), and a 350mg caffeine backbone.

It also contains 100mg DMHA and 200mg DMBA, both of which are not permitted in many sports and organizations.

The blend is designed to deliver energy, focus, and pump in one serving.

Flavors include options like Tropical Punch, Blue Tropical, Cherry Limeade, Pineapple Mango, Firecracker, Snow Cone, and Tiger's Blood.

Pros & Cons

Pros:

  • Fully disclosed formula
  • High-stim blend for advanced users
  • No proprietary blends
  • Several flavor choices
  • Decent pump ingredients

Cons:

  • Stimulant load is too high for beginners
  • DMHA and DMBA are banned in most tested competitions
  • Clumping can occur due to glycerol
  • Tolerance develops quickly
  • Not as extreme in effects as some expect based on the label

Who Should Take It (and Who Shouldn’t)

Best for:

  • Experienced pre-workout users
  • Lifters who want high energy, strong focus, and solid pumps
  • Those who are not subject to drug-tested competition

Not for:

  • Beginners or anyone sensitive to stimulants
  • Anyone who is drug-tested for competition or employment
  • Users who prefer lower-stim or non-stimulant formulas

Ingredients Breakdown

  • L-Citrulline (6,000mg): Supports nitric oxide production and muscle pump.
  • Beta Alanine (3,200mg): Buffers lactic acid, may cause tingling.
  • Glycerol Monostearate (1,500mg): Improves cell hydration and pump, but may clump.
  • Caffeine Anhydrous (350mg): Fast-acting energy.
  • DMHA (100mg) & DMBA (200mg): “Exotic” stimulants for focus and energy; both banned by most organizations.
  • Theobromine (100mg): Smooth stimulant, mild mood lift.
  • Methylsynephrine HCL (20mg) & Alpha Yohimbine HCL (2.5mg): Additional stimulants; alpha yohimbine can increase energy but may cause side effects for some.

How to Use

Mix one scoop (13.7g) with 8–12 oz of water.

Consume 20–30 minutes before a workout.

Start with half a scoop to assess tolerance.

Do not combine with other stimulants.

Limit use to once or twice per week to prevent rapid tolerance.

Final Verdict: Is Demolish Worth Trying?

Demolish Pre-Workout by Frenzy Labz is a fully disclosed, high-stimulant pre-workout.

It’s built for experienced users who want strong energy, focus, and pump, not for beginners or anyone who is drug-tested.

If you want a pre-workout that delivers on label claims with a higher stim blend, Demolish is an option, just know what you’re getting into and use responsibly.

Demolish review

May 20, 2025

Alright I’ve tried demolish about three times and it reminds me of most other dmba pres. very similar to stim shady but this may be a bit more powerful than stim shady because of the alpha yo. There wasn’t any bad side effects and it wasn’t as strong as I expected but it definitely had the goods and I really enjoyed it. It felt fun to workout and it tastes good. I didn’t notice shortness of breath or anger but I remember killing the weights. I felt powerful and had a good time for at least 6 hours. There is a new version that may be even better but someone may prefer stim shady if you want a bit more happy vibes. You will demolish the weights and you will love it. It’s not as strong as the label suggest to be honest but thats true of all the stim Pres

Demolish Pre Workout review

April 4, 2025

Frenzy labs has been in this game for a long time, it's one of the most reputable pre workout companies. I have tried Stim shady from them. And this Demolish has very similiar feel to it like the OG version of Stim Shady.

Let's start with the least important section of the review which is taste. The flavor I have was tropical punch flavor and it was very sweet very enjoyable not typical generic fruit punch flavor . frenzy labs always nail the flavoring system. Mixability is on point.

The experience: Beta Alanine kicks in around 15 minutes and stays for good 15-20 minutes it's not too strong like a medium level but you get your ears and hands itchy. Then what's quickly followed by is the surge of energy it's not too strong, it gradually builds up, initial kick is most likely caffeine.. 350mg of caffeine is the perfect amount for this pre. It does not blow your head of with caffeine and let the other exotic stimulants shine. from 15 20 minutes mark, up to hour it's a gradual climbing and you get the mood elevation, sense of well-being, mental clarity and overall you're motivated to go to the gym. It's sustained clean energy throughout the workout no ups and downs very smooth experience nothing to fear about. In terms of the DMBA I'm not really sure because when I take the DMBA in some pre-workouts I notice the strength output, Like in Crack Barbarian, weights feel light. I think it has dmaj in it but it's very subtle and you don't really feel the moment it kicks in or change your experience but it does contribute to the overall experience and motivation and mostly performance because you have very good endurance with it.

To compare I would say I like the new stim Shady better than this one labels are very familiar but in terms of effect the old version I have and it wasn't that strong or that memorable. I didn't use it much but it got clumped up, turning into gummy texture overtime, most probably due to Glycerol in it.

In terms of pumps it's really good, because you are tuned in your workout and you get good pumps anyway. You might wanna stack some pump pills on top it.

No crash or side effects from it. It's beginner high stim pre workout, for once a week use because of the DMHA and DMBA, which body builds tolerance to it real quick. It has new version now with new label.
