ALPHA SUPPS | STIM JUNKY EXTREME PREWORKOUT
Alpha Supps Stim Junky is a high-stimulant pre-workout delivering 400mg caffeine anhydrous per serving alongside L-Citrulline 6000mg, NeuroPEA (Eria Jarensis), Alpha Yohimbine HCl, and Huperzine A. Available in 6 flavors, Stim Junky is the revamped version of the legendary Grind Nutrition formula — now under the Alpha Supps brand with a refined, fully-loaded high-stim stack. If you’re looking for a pre-workout built for extreme energy, euphoric focus, and skin-splitting pumps, Stim Junky is it.
Some pre-workouts warm you up. Stim Junky turns the heat all the way up.
This isn’t a product for first-timers or people looking for a gentle lift. Stim Junky is built for experienced athletes who’ve maxed out on conventional pre-workouts and need something that actually hits. Originally developed under Grind Nutrition — one of the most respected names in high-stim supplements — Stim Junky is now part of the Alpha Supps lineup, refined without losing an ounce of its intensity. 400mg caffeine, Eria Jarensis for euphoric drive, Alpha Yohimbine for fat mobilization and energy amplification, and Huperzine A for the kind of mental focus that keeps you locked in rep after rep. This is the full stack for people who train at the edge.

Stim Junky vs After Dark Void - Which High-Stim Should You Choose?
Both are elite high-stimulant pre-workouts in the same tier. Here’s the difference:
-
Alpha Supps Stim Junky - 400mg caffeine + Eria Jarensis + Alpha Yohimbine + Huperzine A. Heavy on the nootropic focus stack alongside the stimulants. Best for athletes who want extreme energy and mental sharpness together
-
After Dark Void - equally aggressive stimulant profile with Kanna and Mucuna Pruriens for a different nootropic angle. Best for athletes who want a mood and motivation edge on top of raw energy
Who Is Stim Junky For?
Stim Junky is for experienced pre-workout users only. It’s the right choice if:
- You’ve built up a high stimulant tolerance and standard pre-workouts no longer deliver
- You train early mornings or late nights and need maximum energy fast
- You want both massive physical pumps AND intense mental focus in one product
- You were a Grind Nutrition customer and want the updated Alpha Supps formula
- You’re looking for a full nootropic + stimulant stack without stacking multiple products
Directions
Mix 1 scoop with 8-10 oz of cold water 20-30 minutes before training. First-time users: start with 1/2 scoop to assess tolerance. Do not exceed 1 scoop per 24 hours. Not recommended for individuals sensitive to stimulants, under 18, or pregnant/nursing.
