What should you look for?

Work it out per serving. Tubs differ in weight and in the number of scoops.
Check the doses. 150 to 300 mg of caffeine per scoop and at least 6 grams of L-citrulline. Beta-alanine (3 grams or more) only works if you take it every day.
No blends without doses. If the label does not give the amount per ingredient, you do not know what you are buying.
Training in the evening? Then take a caffeine-free version.

Questions

What is the cheapest pre-workout in the UK?

The lowest price for pre-workout across the shops we track is today Myprotein Impact Pre-Workout: £0.19 per serving (£9.00 per tub of 480 g with code KROTON). Measured on 22 October across 52 pre-workout powders at 4 shops; powder only, based on a serving of 10 grams. The list above is live: the order changes with the discounts. Always work it out per serving, not per tub: a small tub is often dearer per scoop than a big bag on offer.

Is a cheap pre-workout any good?

Sometimes yes, sometimes no. Cheap becomes a problem once the doses suffer, for example less than 6 grams of L-citrulline or a blend without listed amounts. What a good pre-workout should contain: the best pre-workout.

How do you buy pre-workout at the lowest price?

Take a big tub and keep an eye on the brands’ offers. The prices above already include the current discount, so you see straight away what you really pay.

When should you take pre-workout?

About twenty to thirty minutes before training, so the caffeine peaks when you start.

With or without caffeine?

Caffeine gives the most energy and focus. If you train late, take a caffeine-free version so your sleep does not suffer.

Full explanation

The list below is live and sorted by price per serving, with discounts already included. But cheap does not mean well dosed: what works is 150 to 300 mg of caffeine per scoop (the ISSN puts it at 3 to 6 mg per kilo of body weight, source 1 below), at least 6 grams of L-citrulline for the pump and 3.2 to 6.4 grams of beta-alanine a day, which only works if you take it every day (source 2). If a pre-workout falls far short of that, it is cheap because there is little in it.

What doses should a pre-workout have at the very least?

Ingredient	Effective dose	What for
Caffeine	150 to 300 mg per scoop (the ISSN puts it at 3 to 6 mg per kilo of body weight, source 1).	Energy and focus during training.
L-citrulline	At least 6 grams per serving.	Pump and blood flow.
Beta-alanine	3.2 to 6.4 grams a day, only works if you take it every day (source 2).	Buffers acid during repeated hard sets.
