Purity Source Labs is an absolute criminal enterprise at this point. I hope they get their shit turned around and they get new management as soon as possible.
Superdrol is one of those that you might run once or twice in your life and never run again. It's certainly worth experimenting with. I used to run it back in the day at 10 to 30 mg a day.
I love Anadrol and I love Dianabol, but you should pick one. Don't run both together, and if you run testosterone, you better make sure you use an AI as well.
