Product Description
Endurance Circulation Support — Liposomal Nitric Oxide & Herbal Blood Flow Formula
You can have the fittest engine in the world, but if oxygen isn't getting to your working muscles fast enough, you're leaving performance on the table. Here's what most endurance athletes don't realize — circulation, not just VO2 max, is often the limiting factor between a good session and a great one.
Performance Cardio+ is a liquid circulation formula built to help your body deliver more oxygen and blood flow, faster than a standard capsule ever could.
What Makes It Different
Absorbs Before You Even Swallow
This isn't a pill you wait to digest. The liquid uses tiny delivery particles that start absorbing through your mouth tissue in seconds, so your body isn't stuck waiting on your gut to catch up.
A Full Circulation Stack, Not Just a Pump Ingredient
Most "pump" products lean on one amino acid. This one pairs that with a lineup of time-tested circulation herbs, so you're supporting blood flow from more than one angle.
Built for the Long Game, Not Just Race Day
Alongside the fast-acting ingredients, this formula includes herbs traditionally used to support healthy blood vessels over time — useful whether you're 25 or 55 and still chasing PRs.
The Science Made Simple
The core driver here is L-Citrulline, the building block your body converts into nitric oxide — basically the signal that tells your blood vessels to relax and widen so more blood (and oxygen) can move through. That's backed by Hawthorn berry, a heart-supporting herb used for generations, plus Dan Shen and Ginkgo leaf, both traditionally used to support circulation and oxygen delivery to tissue. He Shou Wu and Boswellia round it out, supporting healthy vascular function as you age and train hard year after year.
How to Use It
Dose it right: Take 1 teaspoon (5mL), and hold it in your mouth for 30–90 seconds before swallowing — that's what lets the fast-absorbing particles do their job.
Time it smart: Take it on an empty stomach, about 10–15 minutes before meals or training.
Pro tip: Use it before your longest or hardest sessions, when your oxygen demand — and the payoff from better circulation — is highest.
Who It's For
Endurance athletes, masters competitors, and anyone logging serious training volume reach for formulas like this when they want circulation support that keeps up with their training load, not just their supplement shelf.
This isn't just another pump product. This is whole-body circulation support built for athletes who train for the long haul.

Quicksilver Scientific Performance Cardio+ FAQ's
Everything you need to know before getting started.
Take it on an empty stomach, about 10–15 minutes before meals or training. Many athletes use it before their longest or most demanding sessions when oxygen demand is highest.
Take 1 teaspoon (5mL) daily, or as directed by a healthcare professional. You can repeat dosing throughout the day if recommended by your practitioner.
It combines L-citrulline, which your body converts into nitric oxide to relax and widen blood vessels, with herbs like hawthorn berry, dan shen, and ginkgo leaf that support circulation and oxygen delivery to tissue.
The liquid uses a fine delivery system with very small particles that start absorbing directly through the tissue in your mouth, getting into your system faster than something that has to be digested first.
If you're pregnant, breastfeeding, or taking medication — especially blood pressure or vascular medication — talk to your healthcare provider before use, since circulation-support ingredients can interact.
