The main hit on clomid and nolva is it lowers IGF-1. I was ready to ditch my nolva, but then I read recently nolva only lowers serum IGF-1 levels.
Plasma IGF-1 levels are not correlated with muscle growth from what I read. What is more important is intramuscular IGF-1 levels. Its possible higher plasma IGF-1 may be actually bad since IGF-1 could possible play a role in cancerous tumors' growth. This is probably why many don't see benefits from IGF-1 lr3.
What do you think EF?
