hard to find, but you can find it
i spoke with a few pharmacists on this topic (since i visit TJ regularly for other reasons), and one really nice one told me the only reason it's in low availability (for them) is low demand and its expiration (like 6 mos). she said she can get me (or anyone) some if they place an order for it and call in a couple of times to insure they get it. it might take a week or so to get it, but they can get you all you will ever need that way. she showed me the catalog and the most common one they carry for that purpose is
Gonadotropyl-C in 5000 IU dry (most common) form from Hoechst Marion Rousel and their price was 11 bucks. also, like she said, make sure you get the one which is pure HCG because there is one that is mixed with vitamin B, but i don't like premixed stuff... if i want B, ill buy an amp of B as its probably cheaper (just like sustanon) to buy them separately.
