Penile injection therapy is a well-established, non-surgical treatment option for erectile dysfunction. It may be recommended for men who have not experienced consistent results with oral medications or who need a more predictable response.
Unlike oral medications, injection therapy works locally and is not dependent on digestion, food intake, or medication absorption. For many men, this can provide a faster and more controlled treatment experience.
All treatment decisions are made after a medical evaluation by a licensed provider.

Bi-Mix is a two-medication formulation often used as a starting option for men with mild to moderate erectile dysfunction.
It may be considered for men who are new to injection therapy, prefer a lower-intensity option, or want to avoid certain medication components.
Tri-Mix is one of the most commonly prescribed penile injection formulations. It combines three medications to support a stronger erectile response.
It is often considered for men who have not had consistent success with oral medications or who need a more predictable result.
Quad-Mix is an advanced formulation that adds an additional component to further support smooth muscle relaxation and erectile response.
It may be considered when Tri-Mix does not provide the desired effect.
Super Quad-Mix is a higher-strength formulation reserved for more advanced cases where additional potency may be clinically appropriate.
This option requires careful dosing and close provider guidance.
