Tribulus terrestris extract (standardized for steroidal saponins)

Steroidal saponins may influence luteinizing hormone signaling, which can support natural testosterone production and libido.

Caution: May cause stomach discomfort in some; avoid combining with unknown stimulant products as effects on blood pressure may vary.

L-Arginine HCl

Acts as a nitric oxide precursor, which may relax blood vessels and support circulation and exercise performance.

Caution: May cause GI upset; those with low blood pressure or using PDE-5 inhibitors should be cautious due to additive vasodilation.

Japanese knotweed extract (resveratrol)

Resveratrol may influence estrogen-metabolizing enzymes and antioxidant pathways, supporting a balanced hormone environment.

Caution: May interact with anticoagulant or antiplatelet drugs due to effects on blood flow; stop before surgery.

Ashwagandha extract

Withanolides are studied for modulating stress response and cortisol, which may support recovery and vitality.

Caution: May cause drowsiness or GI upset; use caution with sedatives or thyroid-supporting supplements.

L-Carnitine fumarate

Facilitates transport of fatty acids into mitochondria for energy production, which may support training capacity and recovery.

Caution: May cause mild nausea or fishy odor in some; take with food to improve tolerance.

How they work together

Tribulus and resveratrol focus on hormone balance pathways, while ashwagandha supports stress adaptation that can influence training recovery. Arginine targets blood flow for performance, and carnitine supports cellular energy, rounding out pre- and post-training needs.
