How a Team USA Sprinter Built His Own Supplement Line
RMS Nutrition | Athlete Spotlight
He Ran For Team USA. Then He Built the Supplements the Industry Refused to Make.
How Finn Reiser went from frustrated college sprinter to founder of the first supplement line built exclusively for sprint athletes.
The Problem Every Sprinter Knows
Walk into any supplement store in America and ask for a pre-workout designed for sprinters. You will get a blank stare, followed by someone handing you a neon-colored tub of caffeine and creatine built for bodybuilders doing chest day.
Finn Reiser knew this problem personally. As a competitive sprinter training at the elite level and representing Team USA, he was surrounded by the best coaching, the best facilities, and the best training science available. But when it came to supplementation, the options were either generic mass-market products or nothing at all.
"I would stand in GNC reading labels and none of it made sense for what I actually do," Reiser says. "Every pre-workout was 300mg of caffeine and a pump formula. I run for 10 seconds. I do not need a pump formula."
The disconnect was not just frustrating. It was a gap in the market that nobody seemed interested in closing.
Why the Supplement Industry Ignores Sprinters
The business math is simple. Endurance athletes train year-round, consume supplements daily, and represent a massive addressable market. Bodybuilders are the largest supplement-buying demographic in the world. Sprinters? A niche within a niche.
So every product on the shelf was reverse-engineered from what works for those populations. Beet supplements marketed for marathoners. Creatine products designed for powerlifters. Collagen peptides packaged in pastel containers and sold to women over 50 for skin health.
The research for sprint-specific supplementation existed. Dietary nitrate targets Type II fast-twitch muscle fibers. Creatine monohydrate replenishes phosphocreatine stores that deplete 55% during a 100m sprint. L-citrulline reduces sprint performance decrement between repeated maximal efforts. Hydrolyzed collagen peptides with vitamin C can increase tendon stiffness by 18% in athletes.
The science was there. The products were not.
From Athlete to Founder
Reiser did what frustrated athletes have always done: he started building his own solutions. He studied the research. He consulted with sports nutritionists. He tested protocols on himself during training cycles and competition seasons.
What emerged was not one product but a system. Five distinct supplements, each targeting a different physiological bottleneck specific to sprint performance. Not general fitness. Not bodybuilding. Not endurance. Sprint performance.
That system became RMS Nutrition, and it launched with a premise that no other supplement company had ever operated under: every product in the line is designed for athletes who generate maximal power for 10 seconds, recover, and do it again.
The Five-Product System
NitroSprint is a stimulant-free dietary nitrate formula. Most pre-workouts dump caffeine into the mix, but caffeine actually blunts the nitric oxide pathway that makes dietary nitrate effective. NitroSprint removes the stimulant so the mechanism works. It targets the fast-twitch fibers that define sprint speed. $34.99 for 30 servings.
HydroSprint pairs 5g of creatine monohydrate with a complete electrolyte profile. Most sprinters who tried creatine and quit experienced bloating from the osmotic water shift. The electrolytes balance that fluid shift so you get the PCr benefit without the water weight. $39.99 for 30 servings.
Sprint Recovery uses clinical-dose L-citrulline and L-arginine for between-race recovery at meets. If you have ever felt dead legs in your second or third race of the day, this addresses the ammonia accumulation and nitric oxide depletion driving that feeling. $34.99 for 30 servings.
Fascia Fuel is grass-fed hydrolyzed collagen peptides with vitamin C, following the Baar protocol for connective tissue support. Collagen synthesis declines starting at age 20, right when training loads peak for most sprinters. Clinical research shows 18% greater tendon stiffness versus 8% with placebo. $44.99 for 30 servings.
BrainBolt combines L-theanine with calibrated caffeine for race-day cognitive performance. Your heart rate is already at 160bpm in the blocks. You do not need more stimulation. You need controlled focus without amplified anxiety. $44.99 for 30 servings.
Built for the Sport, Not the Shelf
Every RMS Nutrition product is third-party tested, NCAA compliant, and free of WADA-prohibited substances. The labels include timing protocols specific to sprint competition, not generic "take one scoop daily" instructions.
Reiser did not build RMS Nutrition to compete with GNC or to become the next big supplement brand. He built it because the product he needed did not exist, and he knew thousands of other sprinters were dealing with the same gap.
"There are maybe 200,000 competitive sprinters in the US between high school, college, and post-collegiate," Reiser says. "That is a small market. But those are my people, and they deserve products built for what they actually do."
