Who is PVL Domin8 Pre-Workout for?
Domin8 is a high-dose, research-driven pre-workout with 8 g citrulline malate, 500 mg Nitrosigine, 2-stage 360 mg caffeine, 3.2 g beta-alanine, Lion's Mane, L-Tyrosine, L-Theanine, Huperzine A, electrolytes, and BioPerine. For lifters who want extreme pumps, sustained energy without crash, and razor-sharp focus — and who are not stim-sensitive. Choose it if you're an experienced pre-workout user, train hard 4+ times a week, want Informed Choice testing, and want one of the most complete pre-workouts on the Canadian market. Pairs well with PVL Whey Gold post-workout, PVL Pure Creatine daily, PVL Pro H2O during workout, and PEScience High Volume layered on for extra pump. Skip if caffeine-sensitive (choose PEScience High Volume or Mammoth SWELL instead), or stacking with coffee + energy drinks.
How and when should I use it?
Mix 1 scoop in 350–500 ml cold water 15–20 min before training. Start with 1/2 scoop to assess tolerance — Domin8's 360 mg caffeine is near Health Canada's 400 mg daily cap. Do NOT stack with coffee or other caffeine on the same day. Health Canada caps caffeine at 400 mg/day for healthy adults — track total caffeine across coffee, energy drinks and pre-workout. Avoid late-day use — caffeine half-life can disrupt sleep.
What are the macros?
Zero-cal pre-workout. Citrulline malate 8 g, Nitrosigine 500 mg, total caffeine 360 mg (300 mg anhydrous + 130 mg caffeine citrate equivalent), beta-alanine 3.2 g, Lion's Mane 250 mg, L-Tyrosine 600 mg, L-Theanine 250 mg, Huperzine A. Himalayan salt + Aquamin electrolytes. BioPerine for absorption.
Allergens, gluten-free, vegan, certifications?
Gluten-free per PVL labelling. Verify vegan status on current label image (most pre-workout ingredients are fermentation-derived). Informed Choice Certified — safe for competitive sport. Made in Canada in GMP-certified facility. 30-day default returns apply (yes, even on opened supplements ≤7 servings used). Onward upgrade adds 90-day coverage plus 5% cash back, about 4% premium at checkout.
How fast is shipping in Canada and what does it cost?
Same-day shipping from our Montreal store if you order before 4 PM EST Monday–Friday — hand-packed by our team at our downtown location, often faster than Amazon. Free shipping over $125 CAD subtotal. $12 flat over $50. Delivery: Quebec & Ontario typically 1–3 business days, other provinces 3–7. Express options at checkout. Domestic Canadian shipping — NO duties or customs fees. We're at 3575 Av. du Parc inside Galeries du Parc, downtown Montreal.
Can I pick up in-store? Where are you and is there parking?
Yes — free store pickup, ready in 30 minutes during store hours. We're at 3575 Av. du Parc, Local 5635 inside Galeries du Parc underground mall, downtown Montreal. Our online inventory is the same as our in-store inventory — if it's in stock on the website, it's also available in-store, since every order ships directly from the same physical store. Tell us at the cash and we'll give you a free 1-hour validated parking voucher — drop it in the parking machine on your way out for free indoor mall parking. Store hours: Mon 11 AM–8 PM, Tue–Fri 11 AM–6 PM, Sat–Sun 11 AM–5 PM.
What's your return policy + the Onward 90-day guarantee?
Default: free 30-day return policy — yes, even on opened supplements (as long as you've used 7 servings or fewer). Closed food items over $20 are also returnable. Damaged or wrong items are always replaced free — email info@topnutritionandfitness.com with a photo within 48 hours of delivery. Refunds are issued as store credit (gift card good online or in-store). Heads up: bars that soften or change shape during summer heat are only covered under Onward, not under our default policy (they're still safe + edible — refrigerate flat to reshape).
