Honestly bro, you're better off using a cycle assist. Preload it 2 weeks before running your PH. Then take the dose of the PH as you listed per week. Cycle assist is i think 4 caps 2x a day. That is all you'll need throughout your PH cycle.
Then as you finish the PH, start your SERM the very next day.
It'll look like this.
PH (first thing in the morning)
Cycle Assist 4caps (first thing in the morning) some use their cycle assist a couple hours after the PH, but It doesn't make a huge diff
4-5 hours later
Cycle Assist 4 caps.
Plus you'll get added benefits of using a cycle assist opposed to just milk thistle.
Milk thistle is only a liver support, as where Cycle Assist supports mutiple things throughout the body (research it). You can grab some CEL Cycle Assist on amazon for about $30 bucks.
