Injectable Anadrol dosed at 50mg/ml - typically injectable versions of 17c alkylated orals like D-Bol or Anadrol are less toxic.
Thanks to missing first pass through the liver it shows higher bioavailability (= efficiency) and lower hepatoxity as compared against the oral version.
Can be used as a preworkout only or as a part of a cycle pinned ed, used in the same manner as your regular oral Anadrol.
As preworkout 1ml (50mg) shall be plenty, 2ml max. As part of cycle 0.6 (30) to 1.2ml (60mg), either in 1 dose or split into two.
