Nader Qudimat
Pre-Workout Expert ยท 20 years training

Starts off almost underwhelming, then slowly builds into a long, drawn-out training drive where your body keeps working without that old โ€œrush and chaosโ€ feeling.

The experience is shaped more by steady accumulation than any sudden kick.

Bottom line: A smoother, less chaotic Kill Switch that still drives solid workouts, but loses some of the old aggressive punch and instant intensity.

Kill Switch is genuinely the best dmaa pre workout of this generation.
Where to even start man. The energy alone this thing provides makes me unable to sit still, even on half a scoop. On days where i did full scoops i fell like i was vibrating with pure joy and drive, this shit makes me fucking angry in the best way possible. I am not the type of person that is able to channel anger into power at the gym, until i found this pre at the local crack shack. Put on some good music and close your eyes for a second and you can just feel your body vibrating. 11/10 pre workout, this is my favorite out of all the pres iโ€™ve ever had. i recommend to anyone who wants the strongest shit around cuz ainโ€™t nothing better than this. the come down from this is horrible however, i normally have to sleep it off, but the 4-5 hours before then is probably the best moments of my life. itโ€™s hard to explain you just have to try it. maybe im personally a hyper responder to dmaa but no other preworkout has ever hit this hard. the pump is very mid, but this pre is made for power not sexiness. Starspangled Bloodshot tastes just like a bomb pop popsicle, like spot on.

Euphoria galore
Thereโ€™s been a lot of mixed reviews on this pre workout. Whether itโ€™s batch discrepancies or some people not responding to it. But for me, this ranks on the top 5 pre workouts Iโ€™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. Thereโ€™s little to no pump formula in this, so be sure to stack a pump on top of this if thatโ€™s important to you. I didnโ€™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 donโ€™t respond and apparently thereโ€™s some batches that arenโ€™t hitting as good as others.

One of my favorites
There is so much hype around Killswitch and Iโ€™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 Iโ€™ve ever had and it is consistently putting me in a great mood with a lot of energy that can last like 12 hours itโ€™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 doesnโ€™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 Iโ€™m gonna be optimistic and that all of my different flavors and batches are gonna hit the same. Iโ€™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 itโ€™s too much or not enough.

One of the best since dark energy
As a very experienced stim junkie, Iโ€™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. Thereโ€™s absolutely no need to double scoop with this oneโ€”one scoop will have you feeling like youโ€™re in god mode. The energy, endurance, and focus are unmatched. This is definitely a pre youโ€™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 โ€” 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.

There is so much hype around Killswitch and Iโ€™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 Iโ€™ve ever had and it is consistently putting me in a great mood with a lot of energy that can last like 12 hours itโ€™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 doesnโ€™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 Iโ€™m gonna be optimistic and that all of my different flavors and batches are gonna hit the same. Iโ€™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 itโ€™s too much or not enough.

One of the best since dark energy
As a very experienced stim junkie, Iโ€™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. Thereโ€™s absolutely no need to double scoop with this oneโ€”one scoop will have you feeling like youโ€™re in god mode. The energy, endurance, and focus are unmatched. This is definitely a pre youโ€™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.

Kill Switch is genuinely the best dmaa pre workout of this generation.
Where to even start man. The energy alone this thing provides makes me unable to sit still, even on half a scoop. On days where i did full scoops i fell like i was vibrating with pure joy and drive, this shit makes me fucking angry in the best way possible. I am not the type of person that is able to channel anger into power at the gym, until i found this pre at the local crack shack. Put on some good music and close your eyes for a second and you can just feel your body vibrating. 11/10 pre workout, this is my favorite out of all the pres iโ€™ve ever had. i recommend to anyone who wants the strongest shit around cuz ainโ€™t nothing better than this. the come down from this is horrible however, i normally have to sleep it off, but the 4-5 hours before then is probably the best moments of my life. itโ€™s hard to explain you just have to try it. maybe im personally a hyper responder to dmaa but no other preworkout has ever hit this hard. the pump is very mid, but this pre is made for power not sexiness. Starspangled Bloodshot tastes just like a bomb pop popsicle, like spot on.

Euphoria galore
Thereโ€™s been a lot of mixed reviews on this pre workout. Whether itโ€™s batch discrepancies or some people not responding to it. But for me, this ranks on the top 5 pre workouts Iโ€™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. Thereโ€™s little to no pump formula in this, so be sure to stack a pump on top of this if thatโ€™s important to you. I didnโ€™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 donโ€™t respond and apparently thereโ€™s some batches that arenโ€™t hitting as good as others.
