There is no evidence that l-Arginine in any way enlarges the thymus
gland, merely that it seems to affect the thymus.  This is conjectured
to be connected with the thymus' operation as a part of the immune
system.  The immune system is among the things stimulated by human
somatotropic hormone.

It is likely that the increased thymus activity is a result of the
increased levels of somatotropic hormone, sometimes called a growth
hormone.  (It is actually more of a pre-growth-hormone hormone, if my
informants are correct.)

Clearly anyone suffering from myasthenia would not want to aggravate
the condition by taking l-Arginine.  However, the experience of many
strength athletes using l-Arginine and l-Ornithine as part of a program
to avoid the use of steroid drugs has shown that it helps increase
strength.  This is rather the opposite of myasthenia.
