Yohimbine HCL

Derived from the bark of the Pausinystalia yohimbe tree, Yohimbine is a strong natural alkaloid, traditionally used to support energy, stamina, and circulation. Popular for its stimulating properties, it may help enhance mood, performance, and metabolic function – but since it’s really potent it requires a really careful and accurate approach.

i) ✅ Primary Pharmacological Actions of Yohimbine:

✅ Potential Benefits

• Increased energy and alertness – Acts as a natural stimulant.

• Fat burning support – May enhance fat loss, especially during fasting or workouts.

• Improved blood flow – Supports circulation, particularly in extremities.

• Sexual health – Traditionally used to support libido and male performance.

• Mood and motivation – Can elevate mood and aid focus by influencing neurotransmitters.

ii) Yohimbine Primary Pharmacological Properties

1. α2-Adrenergic Receptor Antagonist

• Main action: Yohimbine blocks presynaptic α2-adrenergic receptors, which normally inhibit norepinephrine release.

• Result: This leads to increased norepinephrine (noradrenaline) levels in the brain and periphery—contributing to heightened alertness, arousal, and fat mobilization.

2. Increased Monoamines (Indirectly)

By blocking α2 receptors:

• Norepinephrine release is increased.

• Dopamine levels may also rise due to disinhibition.

• Serotonin (5-HT) can also be affected, though less directly.

3. Partial Agonist at 5-HT1A Receptors (some evidence)

• There is limited evidence suggesting partial agonist activity at serotonin 5-HT1A receptors, which may explain mood and anxiolytic-like effects at certain doses.

4. MAO Inhibition?

• Some studies have explored mild monoamine oxidase inhibition, but this is not a primary action and likely insignificant at typical doses.

iii) Yohimbine Dosing Overview

🔹 Standard Dosage (Yohimbine HCl):

• Typical dose: 5–20 mg per day, usually divided into 2–3 doses.

• Common single dose: 5–10 mg

• Start low (e.g., 2.5–5 mg) to assess tolerance.

🔹 For Fat Loss:

• 0.2 mg/kg body weight is commonly used in fitness circles (e.g., ~14 mg for a 70 kg person).

• Often taken fasted, as insulin blunts its fat-burning effects.

• Used pre-workout for enhanced effect.

🔹 For Sexual Health:

• 5–10 mg taken 30–60 minutes before activity.

• May support blood flow and libido, especially in cases of mild erectile dysfunction.

🔹 For Cognitive / Mood Support:

• 2.5–10 mg/day, sometimes used in nootropic stacks for alertness and motivation.

• Best taken earlier in the day due to stimulant properties.

iv) Important Considerations & Warnings

Yohimbine – Important Considerations & Warnings

Do Not Use in case of :
