Cytomel and Cynomel - are they comparable?

[Guest guest]

Does anybody have any experience of how Cytomel and Cynomel compare in

terms of their strength, efficacy etc?

I'm on Cytomel but because it's so pricey I'm having to look for a more

reasonable alternative. I can't take Tertroxin because of its lactose

content. Does anyone know if Cynomel contains any?

Anyone any sources for Cynomel?

Thanks,

Louise
