Medication Comparisons
Read from the labels, not from other comparison articles. Every row is marked with how well it is supported — and where two medications are genuinely the same, we say so rather than inventing a difference.
Hair loss
- Finasteride vs DutasterideA labelled hair drug against a prostate drug used off-label — and a head-to-head trial that went to the unapproved one.
- Finasteride vs MinoxidilA prescription tablet against an over-the-counter solution — five years of label evidence against 48 weeks, and a combination neither label describes.
- Propecia vs ProscarOne molecule, two labelled products, and the honest answer to the cheaper-per-milligram question that everybody arrives with.
Sexual health
- Sildenafil vs TadalafilFour hours against thirty-six, a food effect on only one label, and no milligram conversion between them anywhere.
- Viagra vs Cialis vs LevitraTwo of these three brands can still be prescribed. Levitra is discontinued at all four strengths, and its generic is the dearest of the three.
- Generic Sildenafil vs ViagraA 655× gap in what a pharmacy pays, two labels that are otherwise word for word identical, and one blue dye.
- Stendra vs ViagraThe fastest PDE5 inhibitor on any US label against the original — two documented advantages, and a price gap of nearly four hundred fold.
TRT & hormones
- Testosterone Cypionate vs EnanthateBoth labels side by side: identical dose ranges, different oils, and a half-life claim only one label actually makes.
- TRT vs EnclomipheneOne has an FDA label, a dose range and a DEA schedule. The other has no US approval at all — and still beat testosterone gel on sperm counts.
- Enclomiphene vs ClomipheneThe same molecule, minus its longer-lived other half. One is FDA-approved for ovulation induction in women; the other has never been approved in the US at all.
- Testosterone injection vs gelThe transference risk is the whole comparison — a boxed warning on one label, absent from the other. Plus two gel strengths that disagree with each other.
- TRT vs hCGTwo approved drugs with an overlapping male indication, opposite mechanisms — and a fertility claim that appears on no hCG label.
- Subcutaneous vs Intramuscular TestosteroneOne labelled subcutaneous product against 44 intramuscular ones — plus a boxed warning most sources still print that FDA removed in 2025.
- Oral vs Injectable TestosteroneTwice-daily capsules with food against a fortnightly injection of oil — and the boxed warning that belongs to neither of them.
Weight loss & GLP-1
- Semaglutide vs TirzepatideA real head-to-head trial, both labels side by side, and the four words about side effects that appear on one label and not the other.
- Ozempic vs WegovyOne molecule, two applications, a 3.6-fold difference in ceiling — and neither label names the other product once.
- Mounjaro vs ZepboundThe same tirzepatide ladder on both labels — but only one of them names a maintenance dose, and only one is approved in children.
- Brand vs Compounded SemaglutideNo FDA label, no approved concentration, no titration schedule — and the drug shortage that made compounding lawful was declared resolved in February 2025.
- Wegovy vs ZepboundSleep apnoea on one label, teenagers and heart disease on the other, and a four-dose device that halves one bill and is not priced for the other.
- Rybelsus vs OzempicA daily tablet against a weekly injection, two orders of magnitude apart on absorption — and a brand name that now means two different products.
- Saxenda vs WegovyDaily liraglutide against weekly semaglutide, a genuine head-to-head trial, and a 16-week discontinuation rule that exists on one label and not the other.
