Regan’s go-to cheat meal maybe a hamburger, fries, and a milkshake, but he has a very strict regime during bulking and cutting seasons that allows him to be successful. Check out his bulking and cutting stack below:   

Grimes Bulking Stack 

To build toward the gains you’re looking for the off-season, remember this: what you put in your body matters. A lot! The powerful Grimes Bulking Stack is all about bulking the right way. It includes GAT Sport Nitraflex Pre-Workout, Nitraflex Pump, Radical Mass, and JetMASS Creatine System. Read on to learn more about what each component of this stack can do for you. 


This clinically tested, high-intensity pre-training formula is legendary, since it has the potent ingredients athletes the world over rely on to help magnify energy, alertness, strength, stamina, pumps, and free testosterone during workouts.

Nitraflex pre-workout delivers fast, explosive training results for a more powerful body, energy, stamina, Nitric Oxide (NO), and testosterone levels. It contains proven muscle-building L-Citrulline malate, L-Arginine, and L-Arginine Alpha-ketoglutarate (AKG) amino acids, plus Calcium Fructoborate (CFB). That’s a natural, high potency form of Boron shown to support free testosterone.

Stim-Free Nitraflex Pump

This scientifically complex power-output formula has the power to outpump inside every bottle. It’s designed to create dramatically extended muscle pumps while weight training. Impressive, bigger, and longer-lasting NITRAFLEX PUMPS!

Nitraflex Pump is stim-free, so it won’t keep you awake after nighttime training. Even those sensitive to stimulants can take it, and since it’s stim-free, it stacks very well with other GAT products!

Researchers know that inducing advanced, blood-engorged Hyperemia Muscle Pumps takes precision: the uniquely potent, athletics-enhancing formula in NITRAFLEX PUMP! Its clinically-defined dosage matrix of L-Citrulline, Hydromax Glycerol, L-Norvaline, and Pine Bark work together to boost nitric oxide and dilate blood vessels. That produces higher volume flow racing into muscles to fight fatigue. It increases pumps and endurance. Agmatine Sulfate adds Nitric Oxide synthesis, muscle growth, and recovery. A long-term CFB study reported a free testosterone increase of up to 29%.

Radical Mass  

To pack on real mass and muscle, look no further than GAT RADICAL MASS.

GAT RADICAL MASS is a premium weight gainer delivering a HUGE 960 calories and only 6 grams of fat per serving. All, while delivering a deliciously rich milkshake flavor. Radical Mass is fortified with key nutrients and electrolytes in a recommended 3:1 carb-to-protein ratio. Our own Triple-Whey Matrix provides a whopping 50 grams of high-quality proteins.

GAT RADICAL MASS will help pack on size and solid muscle to improve your performance. It’s the perfect choice to help maximize glycogen synthesis, for improved protein upload and recovery. 

JetMASS Creatine System 

This superior Creatine-driven formulation is for athletes with goals for exercise-induced gains in muscle, strength, and performance. It’s specially formulated to increase uptake of Creatine, add lean muscle mass, increase muscle torque, and speed recovery times. JetMASS now contains 5 grams of premium grade Creapure® Creatine monohydrate, the recommended daily level supported by research. The Creatine Monohydrate in GAT JetMASS delivers more creatine uptake into muscles than any other creatine.

Grimes Cutting Stack

As a result, your training stack looks a little different, too. The Grimes Cutting Stack includes GAT Mens Multi+Test Vitamin, FLEXX EAAs+Hydration, Nitraflex Burn, and GAT Whey Protein.
