    How do TriMix injections work?

    • TriMix is a compounded injectable that combines three vasoactive medications — typically alprostadil, papaverine, and phentolamine.
    • Delivered as a small injection directly into the side of the penis, it relaxes smooth muscle and dramatically increases blood flow, producing a reliable erection within 5–20 minutes.
    • Because it acts locally rather than through the bloodstream, TriMix works independently of arousal and is effective even when oral PDE5 inhibitors (like sildenafil or tadalafil) haven't worked — including for men with diabetes, vascular disease, or a history of prostatectomy.

    Formulation

    Trimix T-105: Papaverine 30mg / Phentolamine Mesylate 1mg / Prostaglandin E1 10mcg. Each 5 mL vial contains up to 10 doses at the maximum prescribed dose of 0.50 mL.

    Dosing and safety

    TriMix is self-administered as a small injection 15–30 minutes before sexual activity. It should not be used more than once in a 24-hour period or more than three times per week. Your provider will start you on a conservative dose and gradually adjust it based on your response. We provide detailed injection instructions, ultra-fine needles, and all necessary supplies. Each 5 mL vial contains up to 10 doses at the maximum prescribed dose of 0.50 mL. Because treatment begins at a low dose and is gradually titrated, many patients will have medication remaining at the end of the month. To help maintain sterility, any unused medication should be discarded 28 days after the vial is first punctured, even if medication remains.

    Possible side effects

    • Mild pain or burning at the injection site
    • Minor bruising
    • Prolonged erection
    • Penile fibrosis (with misuse/overuse)

    The most serious risk is priapism — an erection lasting longer than 4 hours. This is a medical emergency that requires immediate care. Proper dosing and injection technique substantially reduce this risk. Do not use TriMix if you have sickle cell disease, severe cardiovascular disease, or a known penile deformity.

    Frequently asked questions

    TriMix is ideal for men who haven't had success with oral ED medications or who need a more reliable solution. It's particularly effective for men with diabetes, a history of prostate surgery, or other conditions affecting blood flow that limit the effectiveness of oral PDE5 inhibitors.

    TriMix is widely considered the most effective ED treatment available, with reported success rates over 90% — including for men who didn’t respond to oral medications like sildenafil or tadalafil. Because it’s injected directly into the penis, it works independently of arousal and nerve signaling, which is why results are so consistent. That said, individual results vary. Response depends on the underlying cause of your ED, your overall health, and finding the right dose — which is why your prescription includes a titration protocol to dial in what works for you. Most men find their effective dose within the first few injections. Just like any local brick and mortar pharmacy, we can’t accept returns or issue refunds on dispensed medication. TriMix is compounded specifically for you, and we don’t guarantee a specific treatment outcome, but our prescribers will work with you on dosing adjustments to get the best possible result.

    Yes. Phenylephrine is available as an add-on at checkout. You may also purchase it at a later date from within your patient portal, though it’s considerably cheaper to purchase at the same time (as we can ship it in the same box, and approve it under one clinical encounter).

    Common side effects include mild pain or burning at the injection site, prolonged erection, and minor bruising. The most serious risk is priapism (an erection lasting more than 4 hours), which requires immediate medical attention. Proper dosing and technique minimize these risks.
