From what I've read online, the recommended dosages run from anywhere to 3 to 30mgs per day for the Rad140. I started at 5mg, then 7.5, and 10. Haven't gone any higher than that. At 30 mg it probably would start getting too expensive (I could buy a large quantity of aas for that price) until the prices start coming down. At 10mg there are really no side effects other than increased lean muscle mass. I'd consider going to 15mg, but probably that would be my max. If you try it post a log
As for sr9009, I've been running it at 15-20mg, which is what I've seen in most other logs online
