No need to dose every day. Even on short esters every other day is adequate. Pinning every day gets old fast plus you will develop a lot of scar tissue
Youre thinking on most orals is correct. However, Proviron does not have the toxicity to the liver that other orals do and can safely be ran for longer periods
Dosage is a little off, and im not real sure about that source. Theres lots of information here to help on sarms. Also check out dylans videos. They are helpful. Umbrella labs is a good option if you want a good spurce as well
