By Bulldog Nutrition Editorial Team | Updated: June 2026
Quick Answer
TC Nutrition Batch 27 is one of the best high-stimulant pre-workouts made in Canada — 325mg of caffeine per serving, 8g citrulline malate (~5.3g pure L-citrulline), 3.5g beta-alanine, 2.5g betaine, and 150mg L-theanine in a fully transparent, no-proprietary-blend formula. Built by a Canadian brand for Canadian lifters, with 40 servings per container. Available at Bulldog Nutrition, an authorized TC Nutrition retailer, in Canada and the US.
Most of the biggest pre-workout brands in Canada are American — imported and formulated south of the border. TC Nutrition is different. Built in Canada, Batch 27 is a fully dosed, clinically transparent high-stimulant pre-workout designed specifically for the Canadian market. It's become one of the most searched pre-workout products in Canada. This review covers the full formula, who should use it, and how it compares to other high-stim options available to Canadian lifters.

Full Formula Breakdown
The 325mg Caffeine Dose with 150mg L-Theanine
At 325mg caffeine, Batch 27 is firmly high-stimulant territory — built for experienced users who have outgrown 200–250mg formulas. What separates Batch 27 from other high-stim options is the 150mg L-theanine. At a 325:150 caffeine-to-theanine ratio, the theanine takes the edge off the sharpest part of the caffeine peak without blunting the overall energy effect — producing a more sustained, focused stimulant experience than a straight 325mg caffeine formula typically delivers.
Pump: 8g Citrulline Malate
At 8g citrulline malate 2:1, you're getting approximately 5.3g of actual L-citrulline per serving — approaching the clinical maximum for nitric oxide production. The addition of ~570mg agmatine sulfate provides a secondary pump pathway, creating a stacked vasodilatory effect that exceeds what citrulline alone delivers. For lifters who prioritize training pump alongside energy, Batch 27's pump matrix is one of the strongest available in a combined energy + pump formula in Canada.
Endurance: 3.5g Beta-Alanine
At 3.5g beta-alanine, Batch 27 exceeds the clinical threshold (3.2g) studied for carnosine buffering. First-time users or those returning after a break will experience skin tingling (paresthesia) for 15–20 minutes — entirely harmless, fades with consistent use.
Power Output: 2.5g Betaine Anhydrous
Betaine at 2.5g matches the clinically studied dose for supporting power output and cellular hydration — one of the more appropriately dosed betaine inclusions in any pre-workout on the Canadian market.
Canadian-Made Transparency
Batch 27 is manufactured in Canada under rigorous quality standards. For supplement buyers who prefer sourcing Canadian-made products, Batch 27 is one of the few pre-workouts in the high-performance category that can genuinely make that claim.
Who Should Take Batch 27?
- Experienced lifters with established caffeine tolerance (250mg+ already in use daily)
- Training sessions requiring maximum intensity — competition prep, strength peaks, high-volume phases
- Canadian buyers who prefer domestically manufactured supplements
- Lifters who value formula transparency with no proprietary blends
Who Should NOT Take Batch 27?
- ✗ Beginners — 325mg caffeine is not a starting point. Start with CBUM Essential or ANS Ritual first.
- ✗ Caffeine-sensitive individuals — 325mg is intense even with L-theanine moderating the delivery
- ✗ Evening trainers — 325mg caffeine will interfere with sleep if taken within 6 hours of bedtime
- ✗ Anyone stacking with other caffeine sources — do not combine with coffee, energy drinks, or other stimulant supplements
- ✗ Under 18 — not intended for use by minors
