BP question. . .

[digimon7068]

I've been on GH for only about 10 days now. When I checked my BP last night, the top number (107) was down about 15 points from a couple of weeks ago and the bottom number (63) was down about 10 points. I know that GH can have a positive effect on your BP, but can it work that fast (in only 10 days)??
