I think a good question would be: what kind of pct regimen are you looking into that you feel is too expensive? If you are looking into pharmaceutical grade SERMs or AIs, they can be quite expensive, but they are really not any better than a lot of reputable research chemical companies. I would search for research chemical clomid or nolva if you are trying to get by on a budget. A full pct is only 35 or less. If you are thinking of running a 17aa oral or methylated steroid, I would look into toremifene, which is not liver toxic. It is slightly more expensive, but at around 50 for a proper pct it pales in comparison to the price of support supps and the actual cycle.
I cannot post any links to research chemical sites, at least I am pretty sure that is a rule, but if you have any questions PM me. Without a proper pct you could really end up worse off than where you started.
