Methandienone or Methandrostenolone are the same products, these are the chemical names but they are better known for the names given to them by their manufacturers, such as Anabol by British Dispensary (thai pinks). The "thai pinks" are the 5mg x 1000 tablets but they also have 10mg x 500 tablets which are yellow, this brand is probably one of the most well known of all the "dianabols" but becoming more popular these days is the Danabol DS made by, or should I say Distributed by Body Research of Thailand, their nick name is "Blue Hearts" because of their shape and colour and they come in tubs of 10mg x 500 tablets. There are many other manufacturers of Methandienone probably to many to mention but a couple of other well known ones are made by S.B. Labs and LA Pharma.
Previously British Dragon was a very popular manufacturer of anabolic steroids but they have been out of business for about 2 years now even though you will still see many websites claiming to sell their products, they are either fake or copies, fakes being the one's with little or no active ingredient in them and copies sometimes having a certain percent of the active ingredient in them but made by an ugl (underground lab)claiming to be the original British Dragon.
These days most people stick with either Anabol by British Dispensary or Danabol DS by Body Research and they are widely available on the net.
