Glad you’re asking — too many people just wing it and end up in a bad spot. I always do blood work before, during (about week 5-6), and after my cycle. The main things I check are liver enzymes, cholesterol, red blood cells, and estrogen levels. There’s a good guide at
https://brentanofabrics.com/art/sust...efits.htmlthat breaks it down pretty well. They mention sustanon 250 for sale too, but honestly, the part about watching blood pressure and regular checkups is more important. If you don’t have a doc who gets this stuff, those private labs are a lifesaver. Better safe than sorry.
