Get more out of your pump and get more gains. Here are three bioactive agents that make it happen.
It's more than cosmetic. A big pump contributes to muscle growth.
That tight, engorged feeling signals anabolic pathways (like mTOR activation), promoting muscle protein synthesis. It enhances the anabolic environment, delivering amino acids, glucose, and oxygen to muscles. The pump is key to the mind-muscle connection, and it even helps with recovery.
And now we can enhance the pump and make it last for hours. It's psychologically motivating and, physiologically, plays a big role in workout performance and gains.
Three substances augment the pump: citrulline malate, citrulline nitrate, and betaine. All three are part of the Igniter ➔ Buy at Biotest formula.
3-way pump
The pump is driven by nitric oxide (NO)-mediated vasodilation, metabolite accumulation, and osmotic changes. Lifting increases blood flow to muscles, causing fluid accumulation in muscle cells (cell swelling).
Here's how citrulline malate, citrulline nitrate, and betaine fit in:
- Citrulline Malate: This compound combines L-citrulline, an amino acid that boosts NO production, with malic acid, which supports energy metabolism. Citrulline malate rapidly converts to arginine, driving immediate nitric oxide synthesis and promoting intense vasodilation, greater muscle perfusion (the delivery of blood/nutrients to muscle), and explosive pumps.
- Citrulline Nitrate: This compound combines L-citrulline with a nitrate group, further boosting NO via a different pathway. It sustains NO levels for hours, prolonging muscle fullness and maintaining maximal nutrient delivery.
- Betaine: The choline-derived compound supports muscle performance, hydration, and recovery by acting as an osmolyte and methyl donor. Betaine complements the synergistic effect of citrulline malate and nitrate by promoting intracellular hydration and cell volumization, optimizing the muscular environment to enhance and extend NO signaling and vasodilation.
Enough science. Tell it like it is.
- It gives you bigger, longer-lasting pumps, bro.
- You'll look more veiny.
- You'll have more endurance during long sets and get more reps.
- You'll feel less fatigued during hard workouts.
- Heavier weights will feel lighter.
- You'll be able to contract a muscle harder.
- You'll recover faster and feel less sore.
All three ingredients are included in Igniter ➔ Buy at Biotest, along with other performance enhancers for razor-sharp focus and dopamine-fueled motivation.
Take Igniter about 20 minutes before your toughest workouts and get ready to feel it.
