- Professional Assessment: Acute protocols at 0.5–0.75mg offer the most predictable libido enhancement for event-specific research with manageable side effects. Accumulation strategies excel in long-term studies requiring sustained baseline effects without timed administration. Pigmentation-concurrent dosing sacrifices libido-specific optimization for dual outcomes and significantly increases adverse event probability.
