My PC has not prescribed HCG before and needs to do a little research. I called a custom medicine shop who's owner I know. He told me he does not do injectables but does the nasal spray version for clients (under prescription only) and has good results. He said he did not see any argument for injectables over the nasal spray. I've tried doing some searching but I haven't found anything definitive yet. Thoughts on HCG nasal spray?
