I've been using it for two months so it's too early to make a judgement (0,5 ml, 5% in stemox).
I'm not sure but I think there is some hair strengthening. No sides at all so far.
I paid about 50-60 $ per gram. I bought it through a GB on polish forum and the source is Kane probably but I'm not sure.
Cause finasteride is quite weak when it comes to hairline/temples.
And don't forget that all androgens (not only dht) contribute to hairloss so it is better to add to your regimen androgen receptor antagonists.
No, I use 25 mg (0,025 g) a day.
I used stemox as vehicle but I switch to ethanol and butylene glycol now.
I use scales to weigh my vehicle - it's 0,5 g (Idk how much ml it is but I suppose about 0,5 ml).
I just use it on the hairline and temples.
