Kudos for persevering with this exciting project. Sounds like you're definitely getting robust effects, but of a fairly unpredictable nature. Your description of the oscillatory nature is resonant to effects found from Maier's lab on PK results: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC58721...more
Wowzer! This is a very promising start indeed. Obviously this is early days but the potential from such a clean set-up is very high. Wish you the best.
