What is Tri-Mix?
Triple-action injectable ED treatment with three complementary active ingredients
Vasodilator / Alpha-Blocker / Prostaglandin
What is Tri-Mix?
Tri-Mix is a compounded injectable medication combining three active ingredients - Papaverine (a vasodilator), Phentolamine (an alpha-blocker), and Prostaglandin E1/Alprostadil (PGE1) - for the treatment of erectile dysfunction. This triple-action formula is widely prescribed by Providers for injectable ED treatment.
Each ingredient works through a different mechanism to increase blood flow to the penis, and together they provide a synergistic effect that may help even for men who have not responded to other treatments. Tri-Mix has been reported to have success rates of up to 90% in clinical practice.
Important Disclosure: Tri-Mix is a compounded medication prepared by FDA-registered 503A compounding pharmacies. Compounded medications are not FDA-approved. They are prepared by licensed compounding pharmacies under the supervision of healthcare providers and may differ in effectiveness, side effects, and risk profile compared to FDA-approved drugs.

What are the benefits of Tri-Mix?
Triple-Action Formula
Tri-Mix combines three medications - Papaverine (relaxes smooth muscle), Phentolamine (blocks vasoconstriction), and PGE1 (activates cAMP pathway) - for a synergistic effect through three different mechanisms of action.
High Success Rate
Tri-Mix has one of the highest success rates among injectable ED treatments, reported at up to 90%. It is often prescribed for men who have not responded to oral medications or simpler injectable formulas like Bi-Mix.
Customizable Options
Available in multiple volumes (2.5ml, 5ml, 10ml) and multiple PGE1 strengths (10mcg to 60mcg per ml), allowing your healthcare provider to customize treatment to your specific needs and response.
Rapid Onset
When administered correctly, Tri-Mix typically begins working within 5-15 minutes, allowing for more natural timing of sexual activity.
How does Tri-Mix work?
Tri-Mix works through three complementary mechanisms to maximize blood flow to the penis:
Papaverine is a vasodilator that relaxes smooth muscle by inhibiting phosphodiesterase enzymes and blocking calcium channels. This causes blood vessels in the penis to dilate.
Phentolamine is an alpha-adrenergic blocker that prevents blood vessel constriction. By blocking alpha receptors, it helps maintain relaxed blood vessels.
Prostaglandin E1 (PGE1/Alprostadil) activates adenylate cyclase to increase cyclic AMP (cAMP), which relaxes smooth muscle through a different pathway than Papaverine. PGE1 is the most potent component and is largely responsible for Tri-Mix's high effectiveness.
The combination of these three mechanisms creates a powerful synergistic effect that results in reliable erections for most men.

The combination of these three mechanisms creates a powerful synergistic effect that results in reliable erections for most men.
- Papaverine relaxes smooth muscle via PDE inhibition
- Phentolamine blocks alpha receptors to prevent vasoconstriction
- PGE1 activates cAMP pathway for additional smooth muscle relaxation
- Three pathways work synergistically for maximum effectiveness
- Effects begin within 5-15 minutes after injection
Think of Tri-Mix like a three-key security system. Each key (medication) unlocks a different lock (pathway) that controls blood flow. While one or two keys might work for some locks, using all three ensures the door opens every time. This is why Tri-Mix has such a high success rate.
How do I take Tri-Mix?
Injectable Form
Tri-Mix is administered via intracavernosal injection directly into the erectile tissue on the side of the penis. Your healthcare provider will provide comprehensive training on proper injection technique and help determine the right formulation strength for you.
- 1Clean the injection site with an alcohol swab
- 2Use a fine-gauge needle (typically 27-30 gauge)
- 3Inject at a 90-degree angle into the side of the penis (avoiding visible veins)
- 4Alternate injection sites between left and right sides
- 5Apply gentle pressure to the injection site for 1-2 minutes
- 6Do not use more than once in a 24-hour period
Important Notes
- Proper injection technique training is essential
- Your provider will determine the appropriate PGE1 strength based on your needs
- Start with lower strengths and titrate up as needed
- Do not inject more than once per 24-hour period
- Limit use to 2-3 times per week
- Store medication properly - Tri-Mix requires refrigeration
- If erection lasts more than 4 hours, seek immediate medical attention

Is Tri-Mix safe?
Tri-Mix has been used for erectile dysfunction treatment for decades and has a well-established safety profile when used as directed under medical supervision. It is widely prescribed by Providers for ED treatment.
The most significant risk with Tri-Mix is priapism, which is more likely than with simpler formulas like Bi-Mix due to the potent three-ingredient combination. Starting with lower strengths and proper dose titration are essential to minimize this risk.
Your healthcare provider will assess your medical history, cardiovascular health, and current medications to determine if Tri-Mix is appropriate for you and which formulation strength to prescribe.

Reversal Injection for Tri-Mix
Because Tri-Mix is more potent than Bi-Mix due to its three-ingredient formula, we strongly recommend having a Reversal Injection available as a safety precaution.
What is the Reversal Injection?
The Reversal Injection contains Phenylephrine, an alpha-adrenergic agonist that constricts blood vessels. If your erection lasts longer than 2 hours or becomes painful, the Reversal Injection can help reverse the effects of Tri-Mix and return the penis to a flaccid state.
When to Use:
- If erection lasts longer than 2 hours
- If erection becomes painful
- As directed by your healthcare provider
Important: Even with a Reversal Injection available, you should still seek immediate medical attention if an erection lasts more than 4 hours. Priapism is a medical emergency that can cause permanent damage.

It is prepared by FDA-registered 503A compounding pharmacies and is not FDA-approved.
Tri-Mix contains three active ingredients while Bi-Mix contains two. The addition of PGE1 in Tri-Mix provides a third mechanism of action, making it more potent and is often prescribed for men who do not respond adequately to Bi-Mix. However, the PGE1 component can cause penile aching or burning that is not present with Bi-Mix.
Tri-Mix is available in 2.5ml, 5ml, and 10ml vials. The 2.5ml vials ship to all 9 eligible states, while 5ml and 10ml vials are only available in Arizona, Colorado, Minnesota, Nevada, and Utah. Multiple PGE1 strengths (10mcg to 60mcg per ml) are available to customize treatment to your needs.
The burning or aching sensation some men experience is caused by the PGE1 (Alprostadil) component. This is usually temporary and subsides within a few minutes. Lower PGE1 strengths may reduce this effect. If the burning is bothersome, discuss with your provider about trying a lower strength or considering Quad-Mix, which may reduce this sensation.
