Advantages of injectable Erectile Dysfunction (ED) medications 

High Efficacy 

Injectable ED medications have a high success rate in producing erections suitable for sexual intercourse. 

Rapid Onset 

These medications typically work within 5 to 20 minutes after injection, providing a quick solution for ED. 

Direct Application 

Since the medication is injected directly into the penis, it often works more effectively and faster than oral medications. 

Option for non-responders 

Injectable medications can be a viable option for men who do not respond well to oral ED treatments. 

Customizable Dosing 

The dosage can be adjusted to meet individual needs, providing more control over the strength and duration of the erection. 

Below is a brief description of each variant:
