Here is how I use RU-58841 for hair loss

• Typically I use the Ruminagen from hemia cosmetics code biohack https://www.hemiacosmetics.com/product/ruminagen-50-ml/ (minoxidil and RU-58841) This will help with hairgrowth and hairloss with the minox and RU.
• I start with .25ml morning and night, before working up to a half ml.
• Twice Per Week I also like to deploy a derma roller.  You can increase how often you use it if you respond well to the twice per week.
• When applying the Ruminagen you can also apply some tretinoin to make the minoxidil work more effectively.

Another thing you can add to this protocol that I find to be effective is GHK-Cu.
