- Doses per vial
- Each 5 mL vial contains up to 10 doses at the maximum prescribed dose of 0.50 mL.

- Risks
- Prolonged erection and priapism can occur in patients receiving penile injection therapy. To minimize the chances of this occurring, titrate TriMix slowly to the lowest effective dose, and never combine with oral ED meds or supplements. Seek immediate medical attention for an erection that persists longer than 4 hours.
- Standard dosing protocol
- Your prescriber may adjust this: Inject 0.05 mL (5 units) at the base of the penis before sexual activity. Increase by 0.025–0.05 mL (2.5-5 units) based on response. Wait at least 24 hours before repeating or increasing the dose. Maximum 0.50 mL (50 units) per dose; no more than 3 doses per week.

Frequently Asked Questions
Who is Trimix for?
Trimix is ideal for men who haven't had success with oral ED medications or need a more reliable solution. It's particularly effective for those with diabetes, prostate surgery history, or other conditions affecting blood flow.
How effective is Trimix?
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.

What's in TriMix? What is the dosing?
RespondWell uses the T-105 formulation: • Papaverine 30mg • Phentolamine Mesylate 1mg • Prostaglandin E1 10mcg. Compounded by Hallandale or Olympia Pharmacy. A 1-month supply is 5 mL; a 3-month supply is 15 mL (three 5 mL vials). Some patients may alternatively be prescribed Papaverine 30mg • Phentolamine Mesylate 2mg • Prostaglandin E1 40mcg.
Standard dosing protocol — your prescriber may adjust this: Inject 0.05–0.10 mL at the base of the penis before sexual activity. Increase by 0.025–0.05 mL based on response. Wait at least 48 hours before repeating or increasing the dose. Maximum 0.50 mL per dose; no more than 3 doses per week.

How long does a vial last?
One 5mL vial holds up to 10 injections at the maximum dose (0.50mL). Dosed every 3 days — the most frequent schedule your provider will approve — that works out to right around 30 days.
Here's the part that actually matters: the vial has a four week life after the first puncture, and that clock is what governs, not how much is left. Even if you're dosing below 0.50mL and have solution to spare, discard the vial after four weeks. The potency and sterility of your vial cannot be assured after that point, regardless of the remaining volume. A half-full vial on day 30 isn't a bonus — it's a vial you shouldn't be drawing from.
Bottom line: Order your refill with enough lead time that you're not stretching a vial past its date to bridge a gap.

Do I have to commit to auto refill?
No. Every plan is fully flexible — pause, delay, reschedule, or cancel whenever you want, right from your patient portal or with a quick message to our team. Your next refill date is always shown on your portal and in every confirmation email, and you'll get an email and text before anything processes, so there are never surprises. Refills run every 25 days on monthly plans and every 85 days on quarterly, timed so your next supply arrives before you run out. The only ask: make changes at least 48 hours before the refill date shown so we can pull the order before the pharmacy fills it. Full flexibility, full transparency — you're always in control.
One note for injectables like TriMix: per FDA/USP guidelines, vials have a 28-day beyond-use date once punctured. Our plans have been priced to ensure you never have to choose between safety and affordability.

Do you offer other formulations like Super TriMix, BiMix, QuadMix, or T-106?
Our standard formulation is T-105 TriMix (papaverine 30 mg / phentolamine 1 mg / PGE1 10 mcg per mL), and it’s the only one we prescribe for new patients. T-105 is a well-established, balanced formula that works for the vast majority of men, and standardizing on it lets our prescribers fine-tune your results through dosing adjustments rather than switching formulas. It also means our pharmacy compounds it at higher volume, which keeps quality consistent and pricing lower.
Super TriMix (papaverine 30 mg / phentolamine 2 mg / PGE1 40 mcg per mL) is available on special request only. It contains four times the alprostadil (PGE1) and twice the phentolamine of T-105, and it’s priced at $249 per 5 mL vial. It is not an option for first-time patients — your prescriber will only consider it after you’ve titrated through T-105 per protocol without an adequate response. Super TriMix is also not available for shipment to Alabama, Arkansas, California, Hawaii, Kansas, Michigan, Minnesota, or Mississippi.
We do not offer BiMix, QuadMix, or T-106.

How fast can I get TriMix?
Fast. Our goal is to have your medication at your door by this time next week, at the latest—and we meet that goal about 94% of the time.
Here's what that usually looks like:
Provider review: Most intakes are reviewed within 4 business hours. More complex medical histories may require additional review by our Medical Director or care team.
Pharmacy processing: Once approved, our partner pharmacy typically prepares and ships your medication within 1–3 business days.
Shipping: UPS Next Day Air is included at no additional cost.
Keep in mind that pharmacy volume, holidays, severe weather, and other carrier delays can occasionally extend these timelines. We'll keep you updated every step of the way.

What are the side effects of Trimix?
Common side effects include mild pain at the injection site, prolonged erection, and minor bruising. The most serious risk is priapism (erection lasting more than 4 hours), which requires immediate medical attention. Proper dosing and technique may reduce these risks.

Do you prescribe phenylephrine injections for prolonged erections or priapism?
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).
Is TriMix available in California?
Yes. TriMix is available to eligible patients in California following a review by a licensed clinician. If you're approved for treatment, your prescription will be sent to one of our partner pharmacies for fulfillment and discreet delivery.
Which states is TriMix available in?
TriMix is available to eligible patients in all 50 states and Washington, D.C.
Every prescription is reviewed by a licensed clinician in your state. If treatment is appropriate, your medication is prepared by one of our partner pharmacies and shipped directly to your door in discreet packaging.
