I'm not saying I've done this, but if you're handy with bitcoin, it's so much cheaper to go through the steroid sites. I saw a sale of 10 x 10mg for reta where the total price was $225 with shipping. That's $22.5 per vial which is absurdly cheaper than any of the "legit" methods of getting GLPs.
And hey, if you want a little test/anavar/tren to spice up your GLP, you can get that in the same order!
