How injection therapy works
Day 1
A physician reviews your history, why oral medicines did not work, and bleeding and blood disorders. You get training on technique and a written priapism plan.
1First dose
Start at a low dose. Inject into the side of the shaft, avoiding the top (vessels) and bottom (urethra); press for 5 minutes.
2Weeks 1-4
The dose is raised in small steps until the erection is firm and lasts under an hour. Alternate sides each time.
3Month 1
Check-in: dose, technique, any bruising, pain or nodules.
4Beyond
Regular reviews to watch for scarring and adjust the dose.

The science of intracavernosal therapy
Quad-Mix is used in specialist practice for severe or post-surgical erectile dysfunction.
Because it is the strongest, the priapism plan matters even more; start low and increase slowly.
Learn moreImportant safety information and common side effects
Intracavernosal injections are highly effective but need training. The main risk is priapism: an erection lasting more than 4 hours is an emergency that can permanently damage the penis. If an erection lasts 2 hours, use your rescue plan (phenylephrine as directed, cold pack, climbing stairs); if it lasts 4 hours, go to the emergency room. Other risks are bruising, pain (more with alprostadil/PGE1), and scarring (fibrosis) with repeated use at the same spot. Do not use with sickle cell disease, multiple myeloma, leukemia, a penile implant, or on blood thinners without your physician's approval. Never use more than once in 24 hours or more than 3 times a week.

Frequently asked questions
How do I use Quad-Mix Injection?
Injected at the base of the penis, as needed, 10–15 min before. The starting prescription is 20 units (0.2 mL) each time. Your physician sets your own dose and it is printed on your label.
What exactly is in it?
Papaverine, Phentolamine, Alprostadil (PGE1), Atropine.
How much arrives in each shipment?
1 vial at the starting strength, shipped to your door from a licensed US pharmacy.
Why not start with Quad-Mix?
Stronger means more risk. Your physician starts with the mildest option that works.
Does the injection hurt?
The needle is the same tiny insulin needle used for diabetes; most men feel a brief pinch. Alprostadil (PGE1) can cause an ache afterwards, which is why Bi-Mix exists.
How fast does it work?
Usually within 5 to 15 minutes, and it does not require arousal to start, although arousal helps.
What do I do if the erection will not go down?
At 2 hours, follow your rescue plan. At 4 hours, go to the emergency room without waiting.
Can I use it with pills?
Only if your physician says so. Combining with PDE5 inhibitors raises the risk of priapism.
When pills are not enough.
