Exactly what Bear said and I'll add make sure you have everything in hand prior to starting your cycle. Including pct. Read all the stickies and self-educate. If at all possible get some BW done before you start so you know your baselines. This way when your done you will know how effective your pct actually is. Not many people get baselines but if you can it's a really smart way to go and you'll appreciate it later on. Consider adding clomid with your nolva for pct. (read pct stickies while your at it)
The above advice is given hoping you've maxed out your natural potential to the best of your ability and your diet and nutrition is on point, right?
