Strongman / Strength athletics
Hafthór Björnsson
Citrulline 8 g · Caffeine 200 mg · Beta-alanine 4 g
A profile built around the demands of strongman: maximal strength and short efforts at extreme intensity (heavy lifts, carries, medleys). Inspired by the style of the giants of the discipline (Hafthór Björnsson, Eddie Hall) — no affiliation, no partnership. A power stack pushed to the caps (creatine, citrulline, beta-alanine, taurine) and a reinforced hydration side suited to a very large frame (glycerol, electrolytes at the cap, pink salt), with high caffeine and tyrosine. No personal stack published: the doses are inspired.
