TriMix cost typically runs between $1 and $3 per injection, or roughly $70 to $250 per 5–10 mL vial, depending on the alprostadil concentration, your prescribed dose, and which compounding pharmacy fills it. For men comparing options for erectile dysfunction, that per-injection price is often lower than a single tablet of brand-name sildenafil or tadalafil, which is one reason TriMix has become a common next step when oral ED medications stop working well enough. This guide breaks down exactly what drives TriMix pricing, how vial size and injection frequency change your real monthly cost, and what else factors into the total price of treatment.
What Determines TriMix Cost?
TriMix is a compounded injectable combining alprostadil, phentolamine, and papaverine, and because it’s compounded rather than a single mass-produced drug, its price depends on several variables that don’t apply to a flat-rate prescription. Three factors matter most.
Alprostadil Concentration and Formula
Alprostadil is the most expensive of the three active ingredients, so higher-concentration formulas cost more per mL to compound. Some clinics also offer variations like Bimix or Quadmix, which adjust the ratio or add ingredients — these formula changes shift the price as well, though standard TriMix remains the most widely prescribed and typically the most affordable of the group.
Vial Size and Injection Frequency
A single vial isn’t a single dose — most patients get 40 to 100 injections out of one 5–10 mL vial, depending on how many mL each dose requires (typically 0.05 mL to 0.12 mL). Since clinical guidance generally limits TriMix injections to no more than three times per week, a properly dosed vial often lasts a patient two to three months, which meaningfully lowers the effective monthly cost compared to looking at vial price alone.
Compounding Pharmacy and Accreditation
Pricing also varies by pharmacy. PCAB-accredited compounding pharmacies — which follow additional sterility and quality standards — may charge somewhat more than non-accredited compounders, but that difference typically buys tighter quality control on a sterile injectable, which is not the place to shop purely on price.
TriMix Cost Per Injection vs. Per Vial
Looking at TriMix cost per vial can be misleading on its own, since a $70 vial and a $200 vial may end up costing about the same per dose once you factor in concentration and yield. Typical ranges reported by compounding pharmacies and telehealth clinics include:
- 5 mL vial: roughly $70–$140, yielding around 50 standard doses
- 10 mL vial: roughly $100–$200, yielding around 100 standard doses
- Higher-strength or specialty formulas: roughly $130–$250 per vial
- Per-injection cost across these ranges: approximately $1.00–$3.00 per dose
These figures are general market ranges, not a quote — your actual TriMix cost depends on your prescribed dose and the pharmacy filling it, so treat any number here as a starting point for the conversation rather than a guarantee.

How TriMix Cost Compares to Other ED Treatments
On a per-dose basis, TriMix is often less expensive than brand-name oral ED medications, and it works through a different mechanism — direct injection into the corpus cavernosum rather than a pill that depends on the nitric oxide pathway — which is why some men who don’t respond well to sildenafil or tadalafil still respond to TriMix. That mechanism difference, not just price, is usually the bigger reason a clinician recommends switching. For a full side-by-side comparison of how the two approaches work, response rates, and who tends to be a better candidate for each, see our TriMix vs. oral ED medications guide.
What Else Affects Your Total TriMix Cost?
The vial price is rarely the entire bill. A few additional line items commonly factor into total TriMix cost:
- Initial consultation: most telehealth and in-person clinics charge a one-time or recurring consultation fee to establish a prescription, commonly in the $50–$100 range.
- Supplies: syringes, alcohol wipes, and a sharps disposal container are typically sold separately and add a modest amount per order.
- Shipping and cold-chain handling: because TriMix is a sterile compounded injectable, some pharmacies charge extra for temperature-controlled shipping.
- Refill cadence: patients injecting closer to three times weekly will refill more often than those using TriMix occasionally, which changes annual cost more than monthly list price does.
Insurance coverage for TriMix is inconsistent — many plans classify compounded ED treatments as a lifestyle medication and exclude them, similar to how they treat oral ED drugs, so most patients budget for TriMix as an out-of-pocket cost. It’s also worth reviewing what to expect from the injection itself before your first dose; our TriMix side effects and safety guide covers what’s normal, what to watch for, and how to manage discomfort at the injection site.
Frequently Asked Questions
Is TriMix cheaper than Viagra or Cialis?
On a per-dose basis, TriMix is often less expensive than brand-name Viagra (sildenafil) or Cialis (tadalafil), sometimes by a wide margin, since a single vial can yield dozens of injections. Generic oral ED medications can be competitively priced too, so the better comparison is usually response and tolerability rather than cost alone — some men simply respond better to an injectable than to a pill.
Does insurance cover TriMix?
Most insurance plans do not cover compounded TriMix injections, since erectile dysfunction treatments are commonly categorized as elective or lifestyle medications. Some patients can use HSA or FSA funds toward the cost; check your plan’s specific exclusions before assuming coverage either way.
How long does one TriMix vial actually last?
For most patients using TriMix up to three times weekly at a standard dose, a single vial lasts about two to three months. Vial life depends on your prescribed dose per injection and how often you use it, so a higher dose or more frequent use will shorten that window.
