Prescriptions require an online visit reviewed by a U.S.-licensed provider. Compounded medications are prepared by licensed U.S. pharmacies and are not FDA-approved. Individual results vary.
Who it’s for
- Persistent fatigue, low libido, or brain fog despite sleep + diet basics
- Want bloodwork-based prescribing, not symptom-guessing
- Comfortable with monthly self-administered protocols
Most men rehearse the conversation for months before they ever say it out loud.
how it works
Oral PDE5 inhibitor for erectile dysfunction — onset in 30–60 minutes, lasts 4–6 hours.
What we can and can't tell you
It restores the plumbing, not the spark — sexual arousal triggers the nitric oxide release it depends on, so it does nothing without it. The right dose (25, 50, or 100 mg) is found by trying, not guessing; a dose that misses isn't failure, it's data for your clinician.
- Who makes it A LegitScript-verified 503A compounding pharmacy, from your prescription — never a gray-market or overseas supplier
- To what standard USP <797> sterile compounding and USP <800> hazardous-drug handling, where applicable
Compounded medications are not FDA-approved, are not reviewed by the FDA for safety or effectiveness, and are not generic equivalents of any brand-name drug.
what the first months look like
Take 30–60 minutes before sex, on an empty stomach for best onset. The window lasts 4–6 hours — you don't have to use it the minute it opens.
Dose calibration. If your dose over- or under-shoots, your clinician moves you along the 25 / 50 / 100 mg range based on response.
Use as needed, maximum once per 24 hours. Check-ins cover how it's working, side effects, and any new medications — nitrates and alpha-blockers change everything.
This treatment covers sildenafil or tadalafil — your clinician matches the molecule to your routine. Tadalafil's longer window is the usual next conversation.
Dosing, step by step
| Doses | 25, 50, or 100 mg — your clinician picks the start and adjusts on response |
|---|---|
| Timing | 30–60 min before sexual activity — empty stomach for best onset — a heavy meal slows it down |
| Ceiling | Once per 24 hours, maximum — hard limit, not a suggestion |
On-demand, not daily. CYP3A4 inhibitors (like ketoconazole) require a reduced sildenafil dose — that's a clinician call, made at intake.
And when it gets rough
- Headache The most common one — hydrate, and it usually fades with the dose window. If it's severe every time, tell your clinician; a dose adjustment is their call.
- Flushing or nasal congestion Vasodilation doing its job elsewhere. Transient — mention it at check-in if it's bothersome.
- Indigestion Take on an empty stomach (which also speeds onset); avoid lying down right after dosing.
- Blue-tinged vision, or an erection past 4 hours The blue tinge is transient and passes. An erection lasting over 4 hours (priapism) or any sudden vision or hearing loss is a medical emergency — seek care immediately, then tell your clinician.
Most men who reach us have been quietly worried far longer than they've been treated, and the first thing we want them to feel is that this is ordinary and fixable. We start low and dial the dose up together, because the right one fits your body and your evening — not the highest number on the shelf. Before anything, we ask about heart medications, especially any form of nitrate, and blood-pressure drugs, since those decide what's safe for you. And honestly, a good part of what we treat here isn't the biology at all — it's the anticipation, and that usually eases once the first time goes the way it should.
