600 milligram plus dose, 8 milligrams per kilogram caffeine and young resistance trained men.

A 2022 crossover, randomized, double-blende placebo-controlled design study

pushed the envelope by assessing the effect of high-dose caffeine,

8 milligrams per kilogram, on muscle strength of recreationally trained men.

For a relatively average person weighing 185 pounds, that would equate to a caffeine dose of

671 milligrams. 21 males who already strength trained, on average, 5.1 hours per week volunteered to participate.

Inclusion criteria included being actively engaged in at least four hours per week of strength

training for a year prior to the study, absence of any pathology or injury that would alter

muscle biology and performance, be a non-smoker, and have a habitual daily intake of less

than 150 milligrams per day of caffeine.

One rep max on bench press.

After taking eight milligrams per kilogram of caffeine,

one rep max bench press strength increased by 7.3%

going from 94.2 kilograms, 207.68 pounds, to 101.1 kilograms, 222.89 pounds.

Almost an entire increment of going from a 35 on the side with the plate to two plates almost.

Pretty impressive.

One rep max on deadlift.

After taking 8 milligrams per kilogram of caffeine, one rep max deadlift strength increased by

10% going from 120.7 kilograms, 266.1 pounds, to 132.8 kilograms, 292.77 pounds. One rep max on squat. After taking eight

milligrams per kilogram of caffeine, one rep max squat strength increased by 9% going from 119.4

kilograms, 263.23., to 130.1 kilograms, 286.82 pounds. Pretty damn significant jumps.
