A regular strength 5-hour Energy shot has 200mg of caffeine. Extra Strength bumps that to 230mg. Both come in the same 1.93 fl oz bottle, so the only real difference between the two red-capped shots on the gas station counter is 30mg. Those numbers come straight from 5-hour Energy's own caffeine facts page, which compares the regular shot to "8 ounces of the leading premium coffee" and the extra strength to a 12 ounce cup.
Why a 2 ounce bottle hits harder than your latte
Behind the bar, we think in shots of espresso and ounces of brewed coffee. 5-hour Energy compresses all of it. At 200mg in 1.93 fl oz, the regular shot works out to roughly 104mg of caffeine per fluid ounce. Extra Strength lands around 119mg per ounce. Compare that to the drip coffee you hand across the counter, where the caffeine is spread across 12 to 16 ounces of liquid, and you can see why people describe the shot as abrupt. You are drinking a full mug's worth of caffeine in two swallows, with nothing to slow you down.
There is no sugar in either version. Per Caffeine Informer's entry, the regular shot has 0 grams of sugar and 4 calories, and the official Extra Strength product page lists zero sugar and zero calories alongside a 2,000mg "energy blend" of B vitamins and amino acids. The company does not break down the blend, so the caffeine number is the one figure you can actually plan around.
One more wrinkle worth knowing. When Consumer Reports lab-tested energy shots back in 2012, regular 5-hour Energy measured 215mg and Extra Strength measured 242mg, per the same Caffeine Informer entry. That is a little above the label on both counts, not below it. Treat the label numbers as the floor, not the ceiling.

For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. How caffeine affects you depends on your own tolerance and health, so treat these numbers as information, not advice.
The math matters here more than with most drinks. One Extra Strength shot is already more than half the FDA's 400mg reference point. Stack it on top of a morning cold brew and an afternoon espresso and you are past it without noticing, because the shot itself is gone in seconds. If you are a barista pulling a double and you drink shift espresso all day, the regular version leaves you more room than the extra strength does, and the 30mg difference between them is smaller than the swing between two different cafes' drip coffee anyway.
Is Extra Strength worth it? Functionally, 30mg is about half a shot of espresso. Most people cannot feel that difference in isolation. What they feel is the delivery speed, which is identical for both. If regular strength already works for you, the extra 30mg is buying you a slightly higher number on the label and not much else.
If you want to compare flavors or grab a multi-pack, 5-hour Energy shots on Amazon come in both strengths.
