Horny goat weed typically begins to work within 30 minutes to 2 hours after consumption if taken on an empty stomach. However, its effects are not instant like prescription erectile dysfunction drugs (Viagra, Cialis), which work within 30-60 minutes. Anecdotal reports suggest horny goat weed might take weeks to months (2-8 months) of consistent use to show noticeable benefits, especially for sexual function and stamina. The supplement generally produces a subtle, steady improvement in libido, energy, and stamina rather than immediate strong effects. Different forms (capsules, tea) and dosages may influence how quickly the effects are felt, with capsules often recommended at 250-500 mg per day. In summary, horny goat weed may start working within a couple of hours for some energy and mood effects, but significant sexual function improvements typically require consistent use over weeks or months.
