Dorian Yates NOX Pump Ultimate 400g

If you want the training pump without the caffeine, NOX Pump Ultimate is the stim-free pre-workout from Dorian Yates Nutrition. 400g tub, designed to stack alongside your stim pre or work as a standalone for sessions where you don't want extra caffeine.

What it is

A stim-free pump-focused pre-workout powder. Mixed with water 20-30 minutes before training. Designed to support blood flow, muscle pump, and training output - without adding to your caffeine load. The 400g tub gives you a working capacity for a serious training block.

Why a stim-free pump product makes sense

There are three good reasons to want a non-stim pump pre. First, you're already running close to your daily caffeine ceiling with coffee, fat-loss caps, or your morning pre. Second, you train in the evening and adding another stim formula would wreck your sleep. Third, you specifically want the pump and training output without the jittery edge a stim pre adds.

A pump pre works on a different mechanism to a stim pre. Rather than caffeine for the central nervous system, the formula typically uses ingredients that support nitric oxide production and blood flow to working muscle [verify source]. The result during a session is the visible muscle pump experienced lifters know, plus the practical benefit of nutrients and oxygen being shuttled into muscle tissue more efficiently during the workout.

Who NOX Pump Ultimate suits

• Lifters who train in the evening and can't stack more caffeine
• People already running a stim pre who want to stack a pump product alongside it
• Anyone who specifically wants the pump without the stim edge
• Customers wanting a clean pre-workout option without affecting sleep
• Older active adults sensitive to high-stim pre-workouts

Not suitable if you're on prescribed blood pressure medication without speaking to your GP first. Pump products can affect blood pressure response by their mechanism.

Why Dorian Yates

Dorian Yates Nutrition's range is built for serious lifters. The 'Ultimate' tier in their range is the upper-end formulation, and NOX Pump Ultimate is the pump-focused product at that tier. We stock it because the stim-free pump category is one most pre-workout shelves don't cover well, and this format gives lifters a sensible option.

Many customers stack this alongside Blood and Guts for their heaviest training days - stim from one, pump from the other, dosed independently. Some use NOX Pump Ultimate alone for evening sessions.

How to use it

One scoop in 300-400ml cold water, 20-30 minutes before training. Drink steadily rather than in one go - the pump effect builds through your warm-up and first working sets.

For evening sessions where you don't want the stim hit, this works as a standalone pre. For heavy daytime sessions you can stack it alongside a stim pre - one scoop of each, mixed separately or together depending on preference.
