Prefuel: What Is In It and How to Get Value From It

A plain account of what Prefuel is, what is in it, and how to use it so that the ingredients actually do their jobs.

What it contains

Prefuel is a sugar-free, zero-calorie pre-workout built on four components:

Creatine monohydrate — the best-evidenced ingredient in sports nutrition. It increases muscle phosphocreatine stores, which fuel short, intense efforts, and reliably improves strength and lean mass over time.
Amino acids — supporting the protein you are getting elsewhere in the day.
B vitamins — cofactors in the pathways that convert food into usable energy. Worth being precise: B vitamins do not give you energy. They are required for energy metabolism, which means a deficiency impairs it and topping up beyond sufficiency does not add anything.
Green tea — providing caffeine along with the polyphenols, notably EGCG, that come with it.

It is free of added sugar and gluten, which distinguishes it from the energy drinks it is meant to replace.

The one thing that determines whether it works

Creatine does not work acutely. This is the single most important thing to understand about any pre-workout containing it.

Creatine improves performance by saturating muscle stores, a process that takes weeks of consistent daily intake at 3 to 5 grams. A dose taken thirty minutes before training contributes to that saturation but does nothing measurable for that particular session.

The practical consequence: if you only take Prefuel on training days before training, the creatine in it is doing far less than it could. Creatine rewards daily consistency, rest days included. Either take it every day, or take creatine separately as a daily habit and treat the pre-workout as the caffeine.

How to use it

Timing: 30 to 45 minutes before training, which suits the caffeine.
Consistency: daily if you want the creatine to earn its place.
Not after mid-afternoon. Caffeine’s half-life is around five hours. Sleep matters more to your training than any pre-workout does, and it is easy to trade one for the other without noticing.
Water. Creatine draws water into muscle cells. Hydration matters slightly more when you are taking it.

What to expect, honestly

Creatine taken consistently produces a real, measurable improvement in strength and lean mass over a training block — it is one of very few supplements about which that can be said without hedging. Caffeine produces a real, immediate improvement in perceived effort and endurance.

Neither produces a dramatic sensation. If you are expecting the flush and tingle of a heavily stimulated pre-workout, this is not that product — and it is worth knowing that the tingling in those products comes from beta-alanine and is entirely unrelated to any benefit.

Who should not take it

Anyone with a cardiovascular condition or uncontrolled high blood pressure, anyone with impaired kidney function, and anyone pregnant or breastfeeding should treat this as a question for their doctor rather than a label. That applies to any caffeinated supplement, not just this one.
