You use RU? I thought it was a scam. I don’t know anyone who’s used it. My brother has a huge bald spot in the back of his head. I guess he’s too far gone.
RU definitely does work, since I've started using it I've filled in the patch on the top of my head, my hair is all around thicker and far less of my hairs are falling out in the shower.
RU is the only product I'm aware of that can prevent hair loss from AAS where is finasteride only works on 5 alpha reductase preventing testosterone conversion to DHT
One problem with finasteride for us (guys/gals that takes aas) is some hormones 5-alpha reduce into less androgenic compounds, for example nandrolone 5-alpha reduces to a less androgenic compound, so blocking 5 alpha reductase would not be the best on nandrolone. Some other hormones are similar.
There is a caveat with RU, it's affinity to the androgen receptor is greater than that of testosterone however it is less than DHT and some other androgens. Good thing this downside can be circumvented by administering higher doses of RU (flooding the scalp with RU so it can occupy the antigen receptor help prevent damaging androgens from reaching the AR receptor.
Another downside with RU is it only has one hour half life (some of it does convert to another anti androgen that has a 23 hour half life, but only a couple percent of it) this is good because it helps keep it localized but obviously bad for other reasons. Because of this I believe multiple times a day dosing, minimum 2 is mandated for maximum benefit.
