If you’re to avoid Nolvadex side effects, if you’re a breast cancer patient simply use the SERM as directed by your physician; that’s fairly simple. Then we have performance enhancement, and in this case, you’ll be using the SERM without such guidance and as with all performance based items at your own risk. Of course, keeping the dosing proper will always serve you best, and proper dosing will vary depending on the point of use. For on-cycle gynecomastia protection, most men will find 10mg per day to be effective if it’s going to be effective; if this doesn’t work, you’ll probably need an Aromatase Inhibitor. As for post cycle use, you will need a larger dosing that tapers down over the course of four to six weeks. In most cases, a total dosing of 40mg per day for a couple weeks, followed by half that amount for a couple weeks and then a 10mg dosing per day for a week or two is perfect.
