I have been using Sustanon 250. A prescription is not need in Cambodia and can be bought in a pharmacy. I have supplier here that sells a box of 10 ampules for $50, it is made in India by Deus medical. I currently inject every ten days with excellent results. I started on seven days for about two months and moved to every 14 days then changed to the current ten days, around 12 days the amount of testosterone slips.
