I found this research paper on the internet, in the study they found that amphetamine use caused muscle atrophy by about 25%. They mainly blame the decrease in appetite caused by the drugs and also the theoretical point of increased cortisol and ATCH as catabolic.
I can't post all the study criteria/results here but here's a snipet, hope it sheds some light:
Amphetamine administration induces disturbances in the hormonal
balance [2], in the metabolism, and in the function of
Although the origin of amphetamine related muscle
damage is not completely understood, the restriction of
caloric intake induced by this drug may contribute to
tissue catabolism [9, 18, 22], since drastic hormonal and
metabolic alterations can be induced by acute food restriction
Amphetamine is known to increase body temperature
as well as cortisol and ACTH concentrations [2, 6]
which per se would lead to a catabolic situation.
