Can You Crush Proscar? The $1/Month Finasteride Hack That Dermatologists Actually Recommend
The Worst-Kept Secret in Hair Loss
Proscar is 5mg finasteride — the same molecule as Propecia (1mg), just 5× the dose, prescribed for prostate enlargement. At Costco, 90 tablets of Proscar cost roughly $12. Cut each tablet into quarters and you get 360 doses of 1.25mg finasteride — a 12-month supply for about $12.
| Option | Monthly Cost | Annual Cost | Same Molecule? |
|---|---|---|---|
| Brand Propecia 1mg | $70–90/mo | $840–1,080 | Yes |
| Generic Finasteride 1mg | $10–30/mo | $120–360 | Yes |
| Proscar 5mg (split into 4) | $1–3/mo | $12–36 | Yes |
| Topical Finasteride | $30–60/mo | $360–720 | Yes |
Is 1.25mg Too Much?
Based on the dose-response curve, 1.25mg suppresses approximately 72% of DHT — essentially identical to 1mg (70%) and even 5mg (72%). The curve flattens so dramatically above 0.5mg that the difference between 1mg and 1.25mg is clinically negligible.

Frequently Asked Questions
Will my doctor prescribe Proscar for hair loss?
Many will — it's a well-known, accepted practice. You may need to specifically ask, as the default prescription is typically generic 1mg. Some telehealth platforms don't offer this option.
Are the quarters exactly equal?
No — pill splitting produces slightly uneven pieces. But given the flat dose-response curve above 0.5mg, the variation (roughly 1.0–1.5mg per quarter) has no clinical significance.
Can insurance cover Proscar for hair loss?
Proscar is typically covered by insurance for BPH, not hair loss. However, the out-of-pocket cost is so low that insurance coverage is rarely necessary.
