Our verdict
Legend V4 is one of the better-formulated mainstream pre-workouts: its core ingredients are at research-backed doses, the label is fully transparent, and the flavors are a genuine draw. The 300 mg caffeine dose is too strong for beginners and late-day training, and there is no verified sport certification, so tested athletes should look elsewhere.

- Lifters wanting full pump and endurance doses

Our review
Legend is the flagship pre-workout from GHOST, the Las Vegas brand known for licensed candy and soda flavors such as Welch's Grape, Warheads and Sour Strips. The current V4 formula is a clear step up from earlier versions: each serving delivers 300 mg of natural caffeine, 6 g of vegan-fermented L-citrulline, 3.2 g of beta-alanine and 2.5 g of betaine, plus 2 g of L-tyrosine, 1 g of taurine, 1 g of choline bitartrate and smaller amounts of theobromine, NeuroFactor coffee fruit extract, Senactiv and AstraGin.
Those headline doses line up well with the research. Six grams of L-citrulline sits in the range studied for blood flow and training volume, 3.2 g of beta-alanine matches the lower end of the 3.2–6.4 g daily range shown to support high-intensity endurance, and 2.5 g of betaine is the amount used in most power and strength studies. Every ingredient is individually disclosed, so there are no proprietary blends to decode. The weaker links are the add-ons: Senactiv, AstraGin and NeuroFactor have limited independent human data.
The main caution is the stimulant load. At 300 mg of caffeine plus 100 mg of theobromine, one scoop is roughly three cups of coffee, and the label warns against taking it within four hours of bedtime. Buyers and TikTok reviewers consistently rate the flavors as the highlight, while the most common complaints are beta-alanine tingles and the price outside of sales.
We could not verify a third-party certification for Legend V4, and GHOST's product page carries a California Prop 65 warning for lead.

Questions buyers ask
How much caffeine is in Ghost Legend V4?
Each scoop contains 300 mg of natural caffeine plus 100 mg of theobromine, a milder stimulant found in cocoa. That is roughly three cups of coffee. The label advises new users to start with half a scoop, to avoid other caffeine sources the same day and not to take it within four hours of bedtime.
Is Ghost Legend vegan and sugar-free?
GNC's listing marks Legend V4 as vegan, gluten-free, soy-free and sugar-free, and the panel shows 10 calories with 0 g of sugar per scoop. It is sweetened with sucralose, and the Blue Raspberry flavor is colored with spirulina extract. Licensed flavors can differ slightly, so check the specific tub.
Is Ghost Legend safe for drug-tested athletes?
We could not verify a third-party sport certification for Legend V4: Ghost's product page does not list one, and NSF's Certified for Sport database lists only GHOST energy drinks. Tested athletes should confirm a current listing for the exact product on the certifier's website before use.
