I'm using metacort with nolva right now for my PCT. I added an additional 3 grams of 7 oxo to this and although there are a few dissolution problems it seems to be working fine. There is a tiny bit of clumping but it has not clogged the sprayer. Other than the 6-oxo induced acne, I think the product is great for PCT.
One word of caution though. I was heating the metacort in a hot water bath, added 3 grams of 7 oxo, and let it sit for about 30 minutes (I forgot about it). When I came back to shake it the soution had apparently seperated into it's constituent elements. One or more of the aqueous layers had super-heated so when I picked up the bottle it spewed boiling metacort all over me.
Fortunately the boiling temp was probably about 120F so I was not scalded. I lost about half of the bottle but a good portion of it went all over my chest..so I recieved a mega dose. I felt pretty serene for about 10 hours.
I added about 6 grams of caffeine to my last bottle of Lipodern Y. To test the systemic vs local theory I put about 4 -5 squirts on mid-afternoon. Despite being physically exhausted from 3 days of mountain climbing, I could not sleep a wink that night until about 5am.
When used in conjunction with rigorous hiking it seemed to work well. Sub-Q fat decreased noticablely in 14 days.
