6g Citrulline, 5g GlycerSize™ for killer stim-free pumps
Caymus Burn Rate isn't your typical stim-packed fat burner from what the label shows. It's a straight-up, fully open stim-free pump and performance mix focused on nitric oxide, hydration, and keeping muscles full. The setup is simple and smart: start with a solid 6,000mg dose of citrulline malate, back it up with arginine AAKG, agmatine, and norvaline for nitric oxide, then add glycerol and electrolytes to pull in more water for that dense, full feel during lifts. This is for people who want to really feel their workouts, not just get hyped.
The star here is 6,000mg L-Citrulline Malate. Citrulline boosts arginine levels better than taking arginine straight, since it skips a lot of the breakdown in your gut. Arginine is key for making nitric oxide, which opens up blood vessels for better flow. At 6g, it's in the sweet spot for improving blood flow, muscle oxygen, and workout performance. In the gym, you'll notice bigger pumps, better endurance, and a stronger mind-muscle connection set after set.
GlycerSize™ brings 5,000mg glycerol powder, a hefty amount for pulling water into cells and boosting hydration. Glycerol acts like a sponge, helping muscles hold more fluid for a rounder, fuller look and feel. It makes the pump wetter and longer-lasting, not just a quick rush. That's why pairing 6g citrulline with 5g glycerol is a killer combo in this mix.

Key Highlights
- 6,000mg L-Citrulline Malate — this is the solid base every good pump product needs. It boosts arginine better than straight arginine, pumping up nitric oxide for wider blood vessels, better flow, and more stamina in your lifts.
- 5,000mg GlycerSize™ glycerol powder — a big dose for super hydration and fuller cells. This makes your pumps feel fuller, wetter, and more 3D instead of just relying on blood flow.
- 1,000mg Agmatine Sulfate — a real dose to support pumps, not just filler. Agmatine helps make nitric oxide effects deeper and longer, so your pumps stick around during the workout.
- 1,500mg L-Arginine Alpha-Ketoglutarate — adds extra support to citrulline. While citrulline handles the big arginine boost, AAKG throws in direct arginine to complete the nitric oxide team.
- 150mg L-Norvaline — right in the useful range for arginase help. Basically, it keeps the setup right for steady nitric oxide when mixed with citrulline and agmatine.
- A real multi-angle pump setup — doesn't put all eggs in one basket. Blends nitric oxide boosts, arginase support, and hydration for a pump that feels complete and layered.
- AstraGin® for better absorption — this patented mix ups nutrient uptake in your gut. 25mg is under the usual 50mg, but it's a smart add in this amino-packed formula.
- Electrolytes from calcium and potassium — not huge amounts, but they fit in a glycerol-based product. They help with fluid balance so the hydration kicks in smooth.

Who Is This For?
- Bodybuilders in hypertrophy mode who rate pre's by fullness, veins, and pump duration. 6g citrulline malate and 5g GlycerSize™ nail that with nitric oxide and water boosts.
- Evening lifters wanting real pre effects without stim sleep issues. Stim-free means better flow and feel, no heart race or crash like caffeine bombs.
- Intermediate folks who handle caffeine separate and like stack control. This covers pumps with citrulline, agmatine, glycerol, norvaline — add stims as needed.
- Cut-phase athletes keeping workouts popping on low cals. Glycerol hydration plus nitric oxide make muscles feel fuller and ready.
- High-volume trainers with supersets, quick rests, long accessories. Better flow from citrulline/agmatine and glycerol fullness keep sessions from going flat.
- Folks who hate hidden blends and want dose checks. Full open label shows exact citrulline malate, glycerol, agmatine, arginine AAKG, norvaline per scoop.
How to Use
Stir 1 scoop into 12-20 ounces of water and down it 20-30 minutes pre-lift. Go higher on water for glycerol to work best, since hydration drives this. If new to glycerol or get belly bloat, try half scoop first then build. Shaker's best — glycerol and aminos mix better shaken. Hits harder with good daily hydration and a light meal 60-120 minutes before, not empty. Add caffeine separate if you want energy, don't double up. Pairs great with creatine, carbs, or extra electrolytes for big days. No cycling needed without stims, but regular use refines your setup. Keep it sealed cool and dry — glycerol can clump with moisture.
What to Expect
Minutes 0-10: You sip it and it's just normal pre-lift vibes, no stim kick. Minutes 10-20: As it hits, it preps your flow and hydration, especially with good water. Minutes 20-40: That's when it shines in your workout — muscles fuller, flow stronger, pump building from citrulline, agmatine, and glycerol. Minutes 40-90: Top sessions keep that dense feel through sets, no early fade. Days 1-7: You figure out water, salt, and meal timing fast for better results. Weeks 2-4: Not like creatine loading, but pumps get more consistent as you lock in routine, hydration, and stacks.

Frequently Asked Questions
Is Caymus | Burn Rate a stimulant pre-workout?
No. Based on the verified formula provided, Burn Rate is effectively a stim-free pump formula built around 6,000mg L-Citrulline Malate, 5,000mg GlycerSize™, 1,000mg Agmatine Sulfate, 1,500mg Arginine AAKG, and 150mg L-Norvaline. It is designed for blood flow, cell hydration, and muscle fullness rather than a caffeine-driven energy rush.
What does the 6,000mg of L-Citrulline Malate actually do?
Citrulline raises arginine levels more reliably than taking arginine alone, which helps support nitric oxide production and vasodilation. At 6g, this is a clinically relevant dose for improved blood flow, better muscle oxygenation, stronger pumps, and more productive training sessions.
Why is GlycerSize™ at 5,000mg such a big deal?
GlycerSize™ provides glycerol, which helps your body retain more water and supports hyperhydration. That means the pump is not just a blood-flow effect; your muscles can also feel denser, rounder, and more volumized during training, especially if your water intake is on point.
How should I take Burn Rate for the best pump?
Take 1 scoop 20-30 minutes before training in 12-20 ounces of water. Because glycerol and nitric oxide support both depend on hydration status, most users get better results when they are well-hydrated and have had a normal meal with some carbs and sodium earlier in the day.
Can I stack Burn Rate with coffee or a caffeinated pre-workout?
Yes. Since Burn Rate is not built around a stimulant panel, it stacks cleanly with coffee, caffeine capsules, or a lower-stim pre-workout if you want added energy. Just avoid blindly combining it with another full pump formula, or you may duplicate citrulline, glycerol, or agmatine unnecessarily.
Is 25mg of AstraGin® enough to matter?
AstraGin® is included for absorption support, and the commonly cited standalone target is often 50mg. At 25mg here, it is best viewed as a supportive addition rather than a fully loaded standalone dose, but it still makes sense in an amino-heavy pump formula.
Will this help with endurance or just pumps?
The primary experience is pump, fullness, and blood flow, but that can translate into better training endurance during high-volume work. Citrulline’s role in nitric oxide production and oxygen delivery often makes later sets feel more sustainable than they do with underdosed pump products.
Can beginners use Burn Rate?
Yes, especially because it is stim-free and fully disclosed. Beginners should still start with half a scoop first to assess stomach comfort and hydration response, particularly because 5,000mg glycerol can feel heavy if water intake is too low.
Do I need to cycle Caymus | Burn Rate?
No formal cycling is necessary because there are no stimulants here to build tolerance against. You can use it whenever you want a stronger pump effect, though consistent use helps you learn the hydration and timing setup that gives you the best response.
Is this really a fat burner?
Not based on the verified active panel. There are no classic thermogenic ingredients listed here; the formula reads as a dedicated stim-free pump and hydration product. If you want appetite suppression or metabolic stimulation, that would need to come from a different type of formula.
