The Science of Going Faster Is Simpler Than You Think
You've trained the miles. You've dialed the nutrition. But when the gun goes off, your muscles still hit that invisible wall — the point where effort stops slows your pace and the winning move gets away. Here's what most athletes don't realize: the limiting factor often isn't just fitness. It's oxygen efficiency. Your muscles are working hard, but your body isn't getting oxygen to them as efficiently as it could. That's exactly what nitrate supplementation is designed to do.
The SiS GO Nitrates Shot delivers 500mg of dietary nitrate per 30ml shot — sourced from beetroot juice concentrate and Amaranthus leaf extract, Informed Sport certified, and backed by a substantial body of peer-reviewed research.
Precision Dosing – Rather than relying solely on beetroot concentrate, SiS combines beetroot juice with Amaranthus leaf extract — a high-nitrate leafy green that lets them hit the 500mg research threshold in a compact 30ml serving. That dual-source approach also delivers a cleaner strawberry flavor than most straight-beetroot shots on the market.
Built for Both Endurance and Intensity – The nitrate-to-nitric oxide conversion pathway benefits more than just long slow distance. In low-oxygen, high-demand conditions — sprint finishes, hard climbs, race-pace surges — nitric oxide production specifically ramps up around fast-twitch muscle fibers, improving both power output and muscle contractile speed. This shot works for runners, cyclists, and triathletes at every race distance.
Informed Sport Certified – Every batch is independently tested for all compounds on the WADA Banned Substances List. For competitive athletes, that's the floor, not a bonus.
What Happens When You Take Nitrates
When you take in dietary nitrates, your body converts them into nitric oxide — a molecule that signals your blood vessels to relax and widen. More blood flow means more oxygen reaching working muscles.
Research shows this reduces the oxygen cost of submaximal exercise by approximately 3–5%, which in practical terms means you're sustaining pace with less perceived effort. That same pathway also benefits high-intensity work: in low-oxygen, high-demand conditions — think sprint finishes, hard climbs, race-pace intervals — nitric oxide production ramps up specifically around fast-twitch muscle fibers, improving both power output and muscle contractile speed.
How to Use SiS GO Nitrates Shot
Loading Protocol: Consume 2 shots (60ml) per day for 1–3 days before your target event or race.
Race-Day Strategy: Take 1 shot 3 hours before the start, then a second shot 90 minutes before. This staggers your blood nitrate peak right through your warm-up and into the first effort.
Pro Tip: For best results, don't use mouthwash or antibacterial products in the hours leading up to your race — the oral bacteria responsible for converting nitrate to nitrite are part of the process.
Elite endurance athletes and team sport competitors have long relied on nitrate supplementation as part of race-week protocols.
This isn't just another beet shot. This is a precision-dosed, independently tested performance tool for athletes who race on race day, not just train on training day.

SiS GO Nitrates Shot FAQ's
Everything you need to know about SiS GO Nitrates Shot.
It improves how efficiently your muscles use oxygen during exercise. When you consume dietary nitrates, your body converts them into nitric oxide — a molecule that signals blood vessels to relax and widen, increasing blood flow and oxygen delivery to working muscles. Research shows this reduces the oxygen cost of sustained effort by approximately 3–5%, meaning you're holding pace with less physiological strain. The same pathway also benefits high-intensity work, improving power output and muscle contractile speed in sprint and surge efforts.
Most beetroot shots either don't hit the 500mg nitrate threshold that research identifies as effective, or they require a much larger volume to get there. SiS combines beetroot juice concentrate with Amaranthus leaf extract — a high-nitrate leafy green — to reliably deliver 500mg in a compact 30ml serving. That dual-source approach also results in a cleaner strawberry flavor than straight beetroot shots, which tend to be earthy and difficult to stomach before a race. And every batch is Informed Sport certified, independently tested against the full WADA Banned Substances List.
Both are valid depending on your timeline. The loading protocol — two shots per day for one to three days before your event — builds sustained elevated nitrate levels in your blood and muscles, which research supports as the more comprehensive approach. The acute strategy — one shot three hours before the start, a second shot 90 minutes before — is designed for situations where loading isn't possible. Plasma nitrate peaks within one to two hours of ingestion and plasma nitrite within two to three hours, so the staggered timing on race day is intentional: it keeps your blood nitrate elevated across your warm-up and into the first hard effort.
This one catches most athletes off guard. The conversion of dietary nitrate to nitrite — a critical step in the nitrate-to-nitric oxide pathway — relies on bacteria that live in your mouth and on your tongue. Antibacterial mouthwash kills those bacteria, which can significantly blunt or eliminate the conversion process and reduce the performance benefit. Avoid mouthwash, antibacterial toothpaste, and chewing gum with antibacterial agents in the hours before and after taking the shot. Brushing with regular toothpaste is fine.
Both — and the mechanism for each is actually different. For endurance, nitric oxide improves blood flow and reduces the oxygen cost of sustained submaximal efforts. For high-intensity work, the nitrate-to-nitric oxide pathway becomes especially active under low-oxygen, high-demand conditions — exactly what fast-twitch muscle fibers experience during sprint finishes, hard climbs, and repeated high-intensity efforts. Research shows nitrate supplementation can improve power output, acceleration, and performance in single and repeated sprint efforts, making it relevant for runners, cyclists, triathletes, and team sport athletes, not just long-distance specialists.
