Q: What supplements should I take while cutting?
A: A 4-product stack: fat burner (Rapidcuts Shredded) + whey isolate (Isoflex) + intra-workout EAAs (MusclEAA Xtreme) + pre-bed casein (CaseinFX) — plus a multivitamin to fill gaps from caloric deficit.
Cutting phases create three problems supplements can solve: (1) muscle preservation during caloric deficit, (2) energy and training capacity when calories are low, and (3) hunger management. The stack below addresses all three using products verified in-stock at our Montreal warehouse.

What to Look For
- Protein per pound bodyweight: aim for 1g per pound to preserve muscle on a deficit.
- Fat burner timing: 30-45 min pre-workout — never within 6 hours of bedtime.
- Intra-workout EAAs: critical for training sessions over 45 min while in deficit.
- Pre-bed casein: the most under-utilized cutting tool — supports overnight muscle protein synthesis.
- Avoid: mass gainers, sugar-heavy pre-workouts, "anabolic" formulas claiming to put on muscle while cutting (you cannot lose fat and gain significant muscle simultaneously beyond beginner gains).
Frequently Asked Questions
How long should a cutting phase last?
Most athletes aim for 8-16 weeks per cut, losing 0.5-1% bodyweight per week. Longer cuts = more muscle loss risk. Use this stack throughout.
Can I do this stack on a vegan diet?
Swap whey isolate for plant protein (PVL Plant-Pro) and casein for a vegan pre-bed protein. Other items work the same.
Will fat burners replace a calorie deficit?
No. Fat burners support energy and metabolic activity but cannot override a calorie surplus. Track macros — supplements amplify a good diet, not replace one.
Should I take creatine while cutting?
Yes — creatine preserves strength and muscle during deficit. The slight water retention is not fat gain. 5g daily, no cycling.
When should I add a pre-workout vs use ACuts vs Rapidcuts Shredded?
Use ACuts for amino-energy + lighter caffeine days. Rapidcuts Shredded when you need full thermogenic. Don't stack both — exceeds caffeine limits.
