CellucorC4 Original Pre-Workout

Overview

Cellucor's C4 Original has been a gym-bag staple since 2011, and its appeal is simple: it is cheap, easy to find and comes in bright, candy-style flavors. The current fifth-generation formula on Cellucor's site lists 200 mg of caffeine, 2 g of CarnoSyn beta-alanine, 1.2 g each of L-citrulline and L-arginine, 1 g of creatine nitrate, 100 mg of PeptiPump lentil peptides and a small huperzine A dose, sweetened with sucralose and acesulfame potassium. Older stock with the previous 150 mg formula is still around, so check the label on the tub you receive.

What reviewers say

Long-term users like Hope Baskett, who reviewed it after three years of use, praise its dependable energy and taste, and a TikTok reviewer gave the newer 200 mg formula a 10 out of 10 for flavor. Critics focus on dosing. FeastGood's review praises the value but still spells out a top reason not to buy, and Dr. Brian Yeung's ingredient-by-ingredient breakdown weighs the research behind each component and lists simpler alternatives. On paper, 1.2 g of citrulline is far below the 6–8 g of citrulline malate used in pump research, and one critical reviewer reported only a mild energy boost with no noticeable pump.

Who it's for

Beginners, budget shoppers and casual gym-goers who mainly want an energy and focus boost from a moderate dose of caffeine. It is also a sensible pick for people who train a few times a week and do not want to pay premium prices for ingredients they will not take consistently.

Bottom line

C4 Original is the cheapest way to try a name-brand pre-workout, at roughly $0.62–$0.80 per serving. You are paying mostly for caffeine and flavor, so upgrade if you want research-level pump and endurance doses.
