Full Review
Apollon Nutrition built their reputation on no-compromise formulas, and Assassin is the crown jewel. This is not a beginner's supplement. It's not even for most intermediate users. Assassin is designed for experienced stimulant users who have built genuine tolerance and need something at the absolute upper end of what's safe and legal.
The Stim Complex: The combined 400mg caffeine (350mg anhydrous + 50mg citrate) alone puts this in the extreme category. Add 200mg Eria Jarensis — a PEA-class compound known for potent euphoric and motivational effects — and you have one of the most powerful stim stacks in any commercially available pre-workout. The caffeine citrate provides faster onset than anhydrous, meaning the effects come on quickly and sharply.
The Pump Stack: Despite being primarily known as a stim product, Assassin doesn't skip on pump ingredients. 6g L-citrulline hits the clinical threshold, and the supporting cast provides real blood flow enhancement. You're not sacrificing pumps for stimulants here — you get both.
The Experience: Users consistently describe Assassin as intense, focused, and bordering on overwhelming for anyone not truly tolerance-adapted. The Eria Jarensis creates a mood elevation that many describe as euphoric. Energy is sharp and forceful, not smooth. This is not the pre-workout you take if you need to wind down afterward.
Who Should NOT Use This: Anyone new to pre-workouts. Anyone with cardiovascular concerns. Anyone who has not assessed their stimulant tolerance at lower doses. Anyone who trains in the evening. Anyone who sleeps fewer than 7 hours.
Value: At $54.99 for 20 servings, the cost per serving (~$2.75) is high. But Assassin is a specialist product — most users take it only for their hardest sessions, not daily.
The Bottom Line: Assassin is the real deal for those who want the most extreme experience available. Clinical pump ingredients, massive stimulant complex, and a fully transparent label from a brand that has never compromised on quality. Approach with serious respect.

Hardcore formula for hardcore lifters

Apollon Nutrition makes products for serious athletes, not casual gym-goers, and Assassin proves it. The stimulant complex is aggressive and effective — this is one of the few pre-workouts where I genuinely feel the performance difference on my heaviest sets. Not for newcomers. For experienced users who want maximum intensity, it's excellent.

Assassin is the real deal for high-stim enthusiasts. The energy is fierce and lasts through my entire training session plus cardio. Pump stack is substantial too — this isn't just a stim bomb, it's a complete formula for serious training. Respect the serving size and don't take it late in the day. Apollon knows who their customer is.
