Been lurking forever glad to be here. I know this is an old post but I have been doing a lot of research on 4 and 1 DHEA so I know of the bioavailability problems with oral use. Does anyone have any experience with injectable? I know of one place that sells it but I won't list it since I'm not sure about the rules. I would think that it would have 100% bio but then one would have to also know of the conversion rate too?
