As long as you have valid prescription with you and you purchase the medicine from the same country ...you will not be in trouble for Test Cypionate or other TRT product.
Yes there are lot of websites that you can buy TRT products from. You would not need any prescription for them. You get the product directly shipped to your address. There is a huge market for that but not all of them are genuine though. You just have to find the right one. Price is much higher though without prescription from those websites.And you don't know if you are getting 100% pure product or not if you decide to purchase from them.
