It's hard to know which ones are reputable sellers though considering no-one is allowed to talk about them.
I recently received my order of Tamoxifen Tabs, counterfeit, the site looked great, very professional, blah blah blah, the blister packs came in an envelope cello-taped to a piece of cardboard. They tasted like chalk and crumbled like chalk with the little bit of saliva on them. Very upset, they now have my cash.
Be very careful when ordering from all online distributors of gray area products.
