People begin the Blood Flow Protocol with different health histories, goals, and experiences with sexual performance. PDE-5 medications work by supporting blood flow and vascular relaxation, and individual responses vary. Your clinician will evaluate how you’re doing over time and guide any adjustments.
Early Changes
Many people notice early changes such as:
Improved firmness with stimulation
Easier transition from arousal to erection
Better consistency during sexual activity
More confidence in sexual performance
These experiences vary based on the medication prescribed, your baseline physiology, and how your body responds.
Timing and Onset
Some medications may take effect within a short window before or during sexual activity, while others support more consistent, daily improvements over time. Your clinician will determine which approach is appropriate for you.
Regardless of the medication, sexual stimulation is required for effectiveness.
Steady Improvements
As the protocol continues, individuals may notice:
More reliable erectile response
Improved satisfaction during sex
Greater ease maintaining erections
Reduced performance-related stress or worry
Many people find the protocol creates a more predictable experience over time, though responses differ widely.
Variability Is Normal
It’s common to experience:
Occasional differences in firmness or duration
Variability based on sleep, stress, hydration, or alcohol
Gradual improvements rather than immediate or uniform results
Occasional fluctuation is normal. Your clinician looks at overall trends when evaluating effectiveness.
If You Don’t Notice Changes Yet
Some individuals see gradual improvements over multiple weeks. If you aren’t noticing the changes you expected, your clinician will review:
Your symptoms
Your dose and timing
Your overall health and medications
Whether a different medication may be more appropriate
Do not adjust your medication on your own. Send a message through your patient portal so your clinician can review.
Long-Term Experience
Over time, many people report:
Better confidence
More consistent performance
Improved satisfaction with intimacy
A smoother, less stressful sexual experience
Your clinician will continue to evaluate your symptoms and goals to ensure your treatment remains appropriate.
