- L-citrulline – An amino acid that is a precursor to arginine, shown to reach superior peak plasma arginine levels than a larger dose of L-arginine.
- L-arginine – An amino acid shown to increase blood flow and vasodilation to support muscle pumps.*
- Quercetin – A bioflavonoid shown to increase key markers of nitric oxide production and reduce a vasoconstricting factor.*
- Red wine fruit extract – Supplies proanthocyanidins − a key polyphenol − which emerging research shows may support the production of nitric oxide.*
- Boron – Shown in human clinical research to increase free testosterone and decrease estradiol in just 7 days. Free testosterone is the most bioavailable form of testosterone and supports the musclebuilding process.
- Rhodiola crenulata and Ginkgo biloba – This combination of ingredients has been shown in a human clinical study to maintain peak testosterone-to-catabolic-hormone ratio and enhance performance.
- Brassica oleracea and Bladderwrack extract – Supplying diindolylmethane and fucoxanthin.
