BTG are the best, but hard to find. SPA is equally as good, easier to find, but their are some very good fakes going around. Know your source and if you are getting for less that $1 US it may be too good to be true....
Considering it's retail in pharmacies is about $4.00 per tab,that is not a terrible deal.BTG's have the highest bioavailability of any oxandrolone out there.Amazing drug.
I remember reading an article about BTG and Ox when it was first being reintroduced on US market. It said how roids are used by more bodybuilders than for whom OX was originally intended and because the guidelines will be so stringent and BTG so vigil, NO Ox will be seen on the black Market....HAHAHAHAHAHAHAHAHAHA!!!!!!!!! But I guess jokes on me because I also remember BTG saying they were producung a 20mg tab along with the 2.5mg....Guess they were just teasing us....
