You don't want to just worry about the liver and kidneys. You also want to worry about your heart health. This is why CoQ10 is one of the best. It's been renowned worldwide as one of the top support supplements for the heart.
When it comes to Equipoise you're not going to go wrong running it 400 mg a week. That's a good dosage. You should see some really good results on that.
Sarms are designed to be mild. You're not going to blow up like you would on steroids. That's the benefit of them: they are mild and have low side effects.
I would recommend Proviron at 25 mg a day. I really think that's an economical way to use it. You'll get good results and you will definitely enjoy it.
