Pre-Workout Expert · 20 years training

Feels floaty with a lighter body feel and strong tunnel-vision focus.

Hits hard and lasts long without dropping off quickly.

Batch variance is real, and weaker batches feel like a different product.

Bottom line: High ceiling, unreliable floor — test one bottle before committing.

Euphoria galore
There’s been a lot of mixed reviews on this pre workout. Whether it’s batch discrepancies or some people not responding to it. But for me, this ranks on the top 5 pre workouts I’ve used. It gave me such an incredible sense of euphoria and mood uplift that any other pre has given me. It gives great energy to power you through your workout. There’s little to no pump formula in this, so be sure to stack a pump on top of this if that’s important to you. I didn’t get any crash from this, just a good amount of energy to get through my workout and will slowly die down as you finish. I would definitely recommend this to anyone but just keep in mind some people don’t respond and apparently there’s some batches that aren’t hitting as good as others.

Kill switch hit or miss
Kill Switch is one of those pre workouts that you’ll either love it or hate it. For me, I love it. It gives me the energy i need in the gym and the euphoria is off the charts. It might be a batch related thing but I’ve gotten 2 tubs and every time I run it, it never disappoints. One thing that it lacks is pumps. If you’re going to use this make sure you stack either pump pills or some citrulline if pumps concern you. I had no side effects, no crash just clean, focused energy throughout my whole gym session. If you’re after a calm, happy focused pre, this can be for you. Just remember, this pre workout is known to to have batch discrepancies so whether it hits for you or not, you’d have to try it out yourself.

There is so much hype around Killswitch and I’m actually very glad there was because it convinced me to buy multiple tubs so far Killswitch is probably one of my favorite people workouts I’ve ever had and it is consistently putting me in a great mood with a lot of energy that can last like 12 hours it’s insane. I also feel great endurance during my workouts this workout The feeling of this pre-workout has been consistent and I enjoyed it every time it doesn’t get my heart beating in a bad way. It is very smooth energy. It feels really nice. I think this is something that can be used and enjoyed by almost everybody, but the amount of negative reviews is really surprising to me. Maybe they had a different tub than me maybe they reacted differently to me, but I’m gonna be optimistic and that all of my different flavors and batches are gonna hit the same. I’ve yet to try all of them yet but so far nothing has let me down. I really enjoyed how Killswitch has a delicious flavor Great energy that lasts for the entire day and it never feels like it’s too much or not enough.

One of the best since dark energy
As a very experienced stim junkie, I’ve tried just about everything out there, and my all-time favorite pre-workout has always been Dark Energy. Every time I test a new high-stim pre, I compare it directly to that standard. Let me tell you, this pre took me to even higher levels. From the moment it kicked in, I was locked in and fully focused for my entire hour and a half workout. No distractions, just pure intensity. There’s absolutely no need to double scoop with this one—one scoop will have you feeling like you’re in god mode. The energy, endurance, and focus are unmatched. This is definitely a pre you’ll want to keep stocked for those days when serious gains are the goal. Highly recommend it!

Kill Switch - Is it the excelsior killer or all hype?
I do not have many complaints about kill switch. It was a fantastic experience overall, with the biggest highlights being the focus and mood elevation. However, I do not believe this pre-workout is anywhere near the level of the legends that are excelsior and dark energy, so any of those claims are all for hype. That being said, the best comparison I could make for kill switch is that it is similar to Wildfire by SoCal Supplements, as both of these pwo's were great when it came to mood elevation. I also appreciate that it is 30 servings, and since you are able to find this product for around $50 at different stores, that is very solid value for money. The pumps were nothing special, but lets be honest, if you are taking a crazy a** stim junkie pre workout like this, you probably shouldn't be expecting crazy pumps (unless it's apollon nutrition). Lastly, I'll talk about the least important part, the flavor. I had the sour candy blood bath flavor, and it was solid; no complaints from me.

Strongest thing I've ever taken
Hit within 20 mins, crazy tunnel focus. The yohimbine is no joke — started sweating 10 mins into my warm-up. Not for beginners. Energy lasted the full 2 hour session.

Taste is rough but the energy is real
Pina Colada flavor tastes more like chemicals but who cares. Pumps were solid and focus was dialed in. Wouldn't recommend for anyone under 180lbs.

Kill switch hit or miss
Kill Switch is one of those pre workouts that you’ll either love it or hate it. For me, I love it. It gives me the energy i need in the gym and the euphoria is off the charts. It might be a batch related thing but I’ve gotten 2 tubs and every time I run it, it never disappoints. One thing that it lacks is pumps. If you’re going to use this make sure you stack either pump pills or some citrulline if pumps concern you. I had no side effects, no crash just clean, focused energy throughout my whole gym session. If you’re after a calm, happy focused pre, this can be for you. Just remember, this pre workout is known to to have batch discrepancies so whether it hits for you or not, you’d have to try it out yourself.

One of my favorites
There is so much hype around Killswitch and I’m actually very glad there was because it convinced me to buy multiple tubs so far Killswitch is probably one of my favorite people workouts I’ve ever had and it is consistently putting me in a great mood with a lot of energy that can last like 12 hours it’s insane. I also feel great endurance during my workouts this workout The feeling of this pre-workout has been consistent and I enjoyed it every time it doesn’t get my heart beating in a bad way. It is very smooth energy. It feels really nice. I think this is something that can be used and enjoyed by almost everybody, but the amount of negative reviews is really surprising to me. Maybe they had a different tub than me maybe they reacted differently to me, but I’m gonna be optimistic and that all of my different flavors and batches are gonna hit the same. I’ve yet to try all of them yet but so far nothing has let me down. I really enjoyed how Killswitch has a delicious flavor Great energy that lasts for the entire day and it never feels like it’s too much or not enough.

One of the best since dark energy
As a very experienced stim junkie, I’ve tried just about everything out there, and my all-time favorite pre-workout has always been Dark Energy. Every time I test a new high-stim pre, I compare it directly to that standard. Let me tell you, this pre took me to even higher levels. From the moment it kicked in, I was locked in and fully focused for my entire hour and a half workout. No distractions, just pure intensity. There’s absolutely no need to double scoop with this one—one scoop will have you feeling like you’re in god mode. The energy, endurance, and focus are unmatched. This is definitely a pre you’ll want to keep stocked for those days when serious gains are the goal. Highly recommend it!

Kill Switch - Is it the excelsior killer or all hype?
I do not have many complaints about kill switch. It was a fantastic experience overall, with the biggest highlights being the focus and mood elevation. However, I do not believe this pre-workout is anywhere near the level of the legends that are excelsior and dark energy, so any of those claims are all for hype. That being said, the best comparison I could make for kill switch is that it is similar to Wildfire by SoCal Supplements, as both of these pwo's were great when it came to mood elevation. I also appreciate that it is 30 servings, and since you are able to find this product for around $50 at different stores, that is very solid value for money. The pumps were nothing special, but lets be honest, if you are taking a crazy a** stim junkie pre workout like this, you probably shouldn't be expecting crazy pumps (unless it's apollon nutrition). Lastly, I'll talk about the least important part, the flavor. I had the sour candy blood bath flavor, and it was solid; no complaints from me.
