I have liquid hydergine too
It would be available thru Unique Nutrition, but it's in glass bottles that are not very appropriate for shipping.
Also, there's a research on pubmed that these exact hydergine tables and liquid hydergine from same manufacturer have equal absorption rate. So liquid in this case doesn't add any benefit. When I was using it I took tabs, since it's faster to take than liquid (you have to draw it with dropper and take right measure).
As for modafinil. One of my suppliers (manufacturer) has made liquid modafinil for research purpose at hospital. Tests have just started recently but it's seems it's more bioavailable than tablets. Results will be published in may next year.
This is not a commercial product, but i'll keep you informed how it worked for me. If it works good I might even offer it for sale
but don't expect it (at least from me) before the jan-feb 2006.
