What Each Ingredient Does
High-Stim Energy
DMHA, Geranium Extract, and caffeine help support aggressive training energy and intensity.†
Tunnel Focus
Jack3d is built to support mental drive, alertness, and focus when training gets demanding.†
Muscle Pumps
AAKG supports nitric oxide production and blood flow for better pump quality during training.†
Strength Output
Creatine Monohydrate supports power, strength, and repeated high-intensity performance.†
Training Endurance
Beta Alanine helps support stamina and delayed fatigue during hard sets.†
Ultra-Concentrated Feel
Jack3d is designed for experienced users who want a stronger pre-workout than basic caffeine-only formulas.†
Serving Parameters
Mix 1–3 scoops with 6–12 oz of cold water and consume one serving daily. On training days, take 30–60 minutes before resistance training. Contents may settle, so shake the container before each use. Store in a cool, dry place to help prevent clumping and discoloration.
Do not exceed 3 scoops per day. New users and stimulant-sensitive users should start with 1/2 scoop to assess tolerance before moving higher. Do not combine with other caffeine, fat burners, energy drinks, or stimulant-containing products.
Jack3d is your high-stim training driver — pair it with muscle-building support, protein, or a dedicated fat burner based on your goal.
