Cordyceps Militaris vs Tongkat Ali (Eurycoma longifolia)

Mechanism

Cordyceps contains cordycepin (3'-deoxyadenosine) and adenosine, which modulate purinergic signaling. Cordycepin activates AMPK, inhibits mTOR, and modulates adenosine receptors (A1, A2A, A3). It enhances cellular ATP production by upregulating mitochondrial biogenesis genes and improving oxygen utilization efficiency. Cordyceps increases EPO production (erythropoietin) via HIF-1alpha stabilization, enhancing oxygen-carrying capacity. Beta-glucans (1,3/1,6) activate innate immune cells via Dectin-1 and complement receptor 3 (CR3). It also relaxes bronchial smooth muscle and enhances adrenal hormone production.

Standard Dosing

1000-3000mg daily (fruiting body extract) or 500-1000mg (concentrated 10:1 extract)

Timing

Morning or pre-workout (energizing). Avoid evening dosing.

Cycle Duration

Cycle 8-12 weeks on, 2 weeks off, or continuous

Side Effects

• Mild GI upset
• Dry mouth
• Insomnia if taken late
• Rare: nausea
• Rare: allergic reaction in mold-sensitive individuals

Contraindications

• Autoimmune conditions (immunostimulatory)
• Bleeding disorders
• Pre-surgery (discontinue 2 weeks prior)

Mechanism

Tongkat Ali contains quassinoids (eurycomanone, eurycomanol) and bioactive peptides (eurypeptides). Primary mechanisms: reduces SHBG binding, freeing testosterone; inhibits aromatase (CYP19A1), reducing estrogen conversion; modulates the HPA axis reducing cortisol; stimulates Leydig cell steroidogenesis via cAMP pathway activation; and may inhibit phosphodiesterase (PDE) enzymes. The net effect is increased free testosterone, improved testosterone:cortisol ratio, and enhanced libido via dopaminergic and NO-mediated pathways in erectile tissue.

Standard Dosing

200-400mg daily (standardized to 2% eurycomanone or 22-40% bioactive content)

Timing

Morning with or without food. Can split AM/PM.

Cycle Duration

Cycle 8 weeks on, 2 weeks off (or 5 days on, 2 off)

Side Effects

• Insomnia
• Restlessness
• Increased aggression (rare)
• Mild GI discomfort
• Elevated heart rate (rare)

Contraindications

• Hormone-sensitive cancers (prostate, breast)
• Pregnancy/lactation
• Children
• Severe liver disease
• Hormone-sensitive cancers
• Concurrent TRT (redundant mechanism)
