PEAK Fusion is a compounded 3-in-1 sublingual liquid combining sildenafil, tadalafil, and apomorphine — targeting both the blood-flow and brain-arousal pathways in a single dose. Through TRUEPEAK RX, a licensed healthcare provider can prescribe PEAK Fusion online if appropriate. No in-person office visit needed. Fast, discreet, and free shipping.
Place the prescribed dose under your tongue about 15 minutes before intimacy and let it dissolve. Sublingual absorption bypasses first-pass metabolism, so PEAK Fusion works faster than a swallowed pill. Do not exceed one dose in 24 hours. Follow the specific dosing instructions from your prescribing clinician.
The most common side effects are headache, facial flushing, indigestion, stuffy nose, back pain, muscle pain, nausea, dizziness, and mild vision changes. Most side effects are mild and temporary. Contact your provider immediately for severe reactions or an erection lasting more than 4 hours.

Got a Question?
PEAK Fusion is a compounded 3-in-1 sublingual liquid combining sildenafil, tadalafil, and apomorphine. Sildenafil and tadalafil are PDE5 inhibitors that address the blood-flow side of erectile function; apomorphine is a dopamine agonist that targets the brain-arousal signal. Together, the formula covers both pathways in a single dose.
PEAK Fusion is only available through TRUEPEAK RX. Start your online evaluation — a US-licensed medical provider will review your case and, if appropriate, write a prescription that ships discreetly from a US-licensed pharmacy directly to your door.
Because PEAK Fusion is a sublingual liquid, absorption bypasses first-pass metabolism and onset is typically around 15 minutes — faster than a swallowed pill. Effects typically last several hours after onset.
The most common side effects are headache, facial flushing, indigestion, stuffy nose, back pain, muscle pain, nausea, dizziness, and mild vision changes. Most are mild and temporary.
The right medication depends on your health history, lifestyle, and preferences. Sildenafil (Generic Viagra®) works fast and lasts 4–6 hours. Tadalafil (Generic Cialis®) lasts up to 36 hours. PEAK Fusion combines three compounds — sildenafil, tadalafil, and apomorphine — for coverage of both pathways. PEAK+ adds a fourth compound (vardenafil). Your provider will help match you to the right option.
