Tadalafil

Tadalafil is a PDE5 inhibitor that supports healthy blood flow by enhancing nitric oxide signaling throughout the vascular system. Taken daily at a low dose, it provides steady support for erectile function, exercise recovery, and overall vascular performance — no timing required.

Daily 5mg dosing — works continuously, not on-demand

You Didn’t Lose Your Edge.Your Vascular System Did.

It’s not in your head. After 30, nitric oxide production declines. Blood vessels lose compliance. The downstream effects show up everywhere — from the bedroom to the squat rack to your ability to stay sharp under pressure.

Tadalafil is a PDE5 inhibitor. It works by enhancing nitric oxide signaling, which relaxes smooth muscle tissue throughout the vascular system. The result is improved blood flow not just when you need it, but all day, every day. This isn’t a band-aid. It’s vascular support at the mechanism level.

How Daily Tadalafil Supports

Vascular Function


Tadalafil inhibits phosphodiesterase type 5 (PDE5), an enzyme that breaks down cyclic GMP (cGMP) in smooth muscle tissue. By maintaining higher cGMP levels, tadalafil promotes relaxation of vascular smooth muscle — improving blood flow throughout the body. Unlike on-demand dosing, daily 5mg tadalafil maintains steady-state plasma concentration. That means consistent vascular support without timing a pill around activity.

Erectile Function

Daily dosing has been shown to significantly improve erectile function scores vs. placebo across multiple 12-week RCTs, with benefits sustained through 2 years of use.

Vascular Health

Tadalafil promotes nitric oxide-mediated vasodilation, supporting healthy endothelial function and blood vessel compliance.

Long-Term Tolerability

Meta-analysis of 6 RCTs (N=1,596) confirmed daily 5mg tadalafil was well-tolerated over 6+ months, with no clinically significant changes in laboratory values, vital signs, or ECG readings.

Frequently Asked Questions

Tadalafil is an FDA-approved PDE5 inhibitor prescribed to treat erectile dysfunction (ED) and benign prostatic hyperplasia (BPH). It works by enhancing nitric oxide signaling and improving blood flow. The daily 5mg formulation maintains steady-state levels so the medication is always active.
On-demand dosing (typically 10–20mg) requires you to take the medication 30–60 minutes before sexual activity. Daily 5mg dosing maintains a consistent therapeutic level in your system, so there’s no need to plan around a pill. Clinical data shows daily dosing may also result in fewer side effects per dose compared to on-demand use.
The most commonly reported side effects in clinical trials include headache, dyspepsia (indigestion), back pain, and nasal congestion. These effects are generally mild and tend to diminish with continued use. Serious side effects are rare but may include sudden vision or hearing changes — contact your physician immediately if these occur. Tadalafil should not be used with nitrate medications.
Many men notice improvements within the first 1–2 weeks. Tadalafil reaches steady-state plasma concentration within approximately 5 days of daily dosing. Full benefits, particularly for men with moderate- to-severe ED, typically develop over 4–12 weeks as consistent vascular support builds.
Yes. Tadalafil is a prescription medication. A licensed Relm physician will evaluate your health history and determine whether daily tadalafil is appropriate for you. No in-person visit is required.
Tadalafil interacts with certain medications, including nitrates (used for chest pain) and alpha-blockers. Your Relm physician will review your full medication list during your evaluation. Do not take tadalafil with nitrate medications — this combination can cause a dangerous drop in blood pressure.
Relm operates outside of insurance networks to keep pricing transparent and accessible. No insurance is needed. Your subscription includes physician consultation, ongoing monitoring, and medication delivery.
Yes — many Relm members use tadalafil alongside TRT or other hormone optimization protocols. Your physician will coordinate your full protocol to ensure compatibility and monitor for interactions.
