PreHD Elite

Most pre-workouts contain four grams of citrulline and no glycerol at all. Elite carries eight grams of each. Citrulline drives nitric oxide production to widen blood vessels; glycerol pulls water into the muscle. One increases the flow, the other increases what is being carried. Together they produce a fullness that a nitric oxide ingredient cannot achieve alone.

Caffeine creates alertness by blocking the signal that tells you that you are tired. That is not the same as clarity. Elite uses Lion's Mane, Alpha GPC, choline bitartrate, Bacopa Monnieri, Huperzine A and tyrosine to support cognition directly, which is why it produces a locked-in feeling rather than a wired one.

Peak O2 is an organic mushroom blend included at two grams to support oxygen utilisation and work capacity. Aquamin adds a marine-sourced mineral complex, and Astragin is included to support absorption of the formula.

Caffeine tolerance climbs. Evening sessions cost you sleep. Some days you have already had three coffees before you reach the gym. A stimulant-free pre-workout gives you the pump and the focus without adding to any of that, and if you want caffeine on a given day you can add exactly as much as you want with StimHD.

Mix one scoop with 10 to 12 oz of cold water 20 to 30 minutes before training. Shake it properly. Eight grams of glycerol needs a real shake in enough water to dissolve fully.
