Magnum Pharmaceuticals spells it Turnibol, but the contents are the familiar 4-chlorodehydromethyltestosterone, 10 mg to a tablet and 50 tablets to the box.
This is an oral androgen carrying a chlorine atom at the 4-position plus an additional double bond, a pairing that leaves it unable to convert into estrogen and comparatively mild in androgenic character. Like other 17-alpha-alkylated orals it reaches circulation intact, which is why this family is discussed in terms of liver load rather than injection technique.
Magnum builds its catalogue mainly around oral tablets.
