Got Questions
Frequently Asked
FAQ
How does STIMULYZE™ MAX™ compare to other pre-workouts on the market?
Most pre-workouts hide behind proprietary blends and underdose every ingredient except caffeine. STIMULYZE™ MAX™ delivers full clinical doses across the board — 6g L-Citrulline for pump, 3.2g Beta-Alanine for endurance, 500mg L-Tyrosine and 200mg Alpha GPC 90% for mental focus, 145mg L-Theanine to smooth out the caffeine, and 290mg Caffeine Anhydrous for clean, sustained energy. Nothing hidden, nothing underdosed.
Is 290mg of caffeine too much?
That depends on your tolerance. If you're an experienced pre-workout user, 290mg is going to hit just right. If you're caffeine-sensitive, start with a half scoop and work your way up. Don't be a hero on day one.
Will I crash after the workout?
STIMULYZE™ MAX™ is formulated to minimize the crash. L-Tyrosine supports sustained dopamine production and L-Theanine smooths out the stimulant edge so your focus doesn't nosedive post-workout. Stay hydrated and eat properly.
Can I stack STIMULYZE™ MAX™ with other Species products?
100%. It pairs perfectly with ISOLYZE™ post-workout for recovery, ARTHROLYZE™ ELITE™ for joint support, and OMEGALYZE™ for daily anti-inflammatory coverage. Just don't stack it with SOMALYZE™ right before bed.
Will I feel the Beta-Alanine tingle?
Probably, yeah. That tingling sensation (called paresthesia) is totally normal and harmless — it's just Beta-Alanine doing its thing. Most athletes learn to love it.
Are these products safe for drug-tested athletes?
Yes. Every batch is third-party tested for banned substances and contaminants. We don't cut corners on compliance.
Can I take STIMULYZE™ MAX™ every day?
You can, but we recommend cycling stimulant-based pre-workouts. A common approach is 5 days on / 2 days off, or taking a full week off every 8–10 weeks to reset your caffeine sensitivity.
What if I don't see results?
Hit us up. Our customer service team will help you dial in your timing, dosing, and training approach. We stand behind every product we make.
