We created Twitch Faster to be the perfect pre-workout for rugby players. It’s a potent, Vitamin-based supplement designed to give you focus and natural energy. Ruggers across the country agree that Twitch Faster is the difference between dreading workouts and loving training. The most common feedback we get is… I love that it doesn’t give me the jitters.

If you’re reading this before purchasing Ruck Harder, we suggest heading over to the No2 Max and Twitch Faster product pages. These pages contain more specific information about the use of these supplements in isolation. The rest of this protocol section will focus on the protocol for combining No2 Max and Twitch Faster to maximize your physical performance during rugby training and games.

Ruck Harder at Training

Rugby training usually goes for about 2 hours. This will vary depending on your club and team, but we’re basing our protocol on the fact that you’ll be training for between 90 and 120 minutes. Because No2 Max needs to be digested and absorbed into your bloodstream, its our recommendation that you take it before your pre-workout.

With that done, we suggest taking 3/4 of a single cup of pre-workout mixed into 500ml of water at least 10-15 minutes before rugby training starts. If your sessions are slightly longer and you have a decent warm-up period, you could actually consider taking your pre-workout at the start of your warm-up. This will let it kick in during warm ups so that when you start drills, you’re all set.

Ruck Harder during Games

This protocol is similar to training except for the timing. Obviously, you can’t be drinking pre-workout as you run onto the field, because you want it to have already kicked in. So for games, make sure you take Twitch Faster when you’re warming up.


Towards the end of a rugby game, when your muscle glycogen is depleted, athletic performance starts to decline. You glance at the bench, hoping there’s a fresh option to replace you. The feeling of having emptied the tank with 15 mins still on the clock is the worst. But Ruck Science has the solution. No2 Max is a potent nitric oxide booster designed to give you abundant energy on the rugby field so you can go a full 80 without feeling like a passenger.

    After trying all the products Ruck Science had to offer, I have to say, these two are by far my favorites. If you’re like me, and your gym sessions take place after a long day of work, this bundle will change the way you lift. Twitch gives you that initial boost you need, without overloading you with carbs (gotta keep keto, you know?) and the NO2 comes right behind to sustain you. No longer to my nights feel wasted because of fatigue. When I hit the weights, Ruck Science helps me hit harder.
