From reading another thread there was mention of a product "Sustain Alpha" (Primordial Performance is the maker) which is also advertised on this site..
This thread talks about it
Link but it's from 2 years ago when the makers were looking for testers to help out..
Not sure if it's been decided if it's a cast iron 100% alternative to HCG , but it's an orally taken remedy which would be my preference for when I hope to start a cycle in November.. Product is available
