Then I expect your Anavar is not good.
Where Anavar can fall short as an anabolic is if it's used alone or only in combination with things like Masteron, Primobolan, or trenbolone. When testosterone, Dianabol, or Anadrol are present, it has quite high potency (effectiveness per milligram.) Adding 350 mg/week oxandrolone (Anavar) is somewhat more potent than adding the same amount of, for example, Masteron. Definitely a decent addition to 500 mg/week testosterone.
But oxandrolone is an often-faked or underdosed product, because it's one of the most expensive per kilo of raw material.
