Hey D+S, I lurk a lot but don't post much. Really appreciate the good advice and discussion thrown around here, and I have a question that I haven't yet seen discussed, so... How hard are amphetamines (long-term) on the body? Will taking them impede muscle growth? I am referring specifically to ADHD/Narcolepsy medications such as adderall and dexedrine, and to higher-end medicinal doses (say, around 200 mg a week). I know that amphetamines suppress the appetite, but is it not possible to get sufficient calories/protein from peanut butter and milk and similar stuff when the medicine kills the appetite? If one takes them early in the day, they shouldn't interfere with rest very much. I would like to know if amphetamines stunt muscle synthesis by their chemical nature, not by their effects on appetite, rest, etc. I'm also curious as to how hard these medicines are on the body and the brain. If any of you know, please share. I'm curious to hear the truth, including your opinions on whether these medicines have significant risks the drug companies don't talk about. Thanks.
