Finasteride / Dutasteride vs Magnesium
Both are used for hormones & testosterone. Here's how they compare on human evidence, mechanism, safety and availability — in plain English.
| Finasteride / Dutasteride | Magnesium | |
|---|---|---|
| Human evidence | ★★★★★ | ★★★★☆ |
| Legal status | FDA Approved | OTC Supplement |
| How it works | Inhibit 5α-reductase (SRD5A2), blocking testosterone→DHT conversion. DHT drives male-pattern hair loss and prostate growth. Finasteride hits type II; dutasteride hits I and II. | Cofactor for 300+ enzymes including ATP synthesis (ATP is biologically active as Mg-ATP), and a natural NMDA-receptor gate blocker (reduces neural excitation). Modulates the HPA axis, lowering cortisol. 50–60% of adults under-consume it… |
| In plain English | Testosterone gets converted into a stronger cousin (DHT) that kills scalp follicles. These drugs block that conversion to save hair — but for a minority, lowering DHT dents libido/mood ("post-finasteride" concerns). | A mineral your body uses in hundreds of reactions and burns through when you train and stress. Topping it up — especially glycinate at night — reliably improves sleep. |
| Bottom line | Most effective hair-loss drug; weigh the sexual-side-effect risk honestly. | Cheap, safe, most athletes are low. Glycinate before bed. |
| Availability | Available over the counter | Available over the counter |
