PCT isnt expensive. If you can't afford that, you probably are going to have a hard time affording the food it will take to build and maintain muscle. But I can tell you first hand, there were times that I was BROKE!!! I'm talking dirt broke, and I still managed to find the means to eat what I needed to. I was broke when I did my first contest and I was still able to eat over 300g protein, mostly from solid foods. So, if you are struggling with funds, you're going to have to get creative. BB is a lot of things, but one thing BB isn't, is cheap ;)
If you are going to cycle, do it right. If you need to wait an extra week, or month, do so, so that you can buy everything you need, at once. You want to have everything on hand. Trust me, This is a lesson you don't want to have to learn the hard way. You can run test only at 250mg EW and make great gains. Here is what the cycle will look like :
test e 250mg EW, or every 5 days, if you want to, and can afford it.
adex .5mg 2-3x wk
2 wks after last shot, start PCT. 40mg nolvadex ED for 1 wk. Then 2 more wks at 20mg ED
