I'm sure someone will jump in if I am incorrect here but....temp raises is bp dont pose a big threat particularly at that level. The problem is at excessive levels over a long period of time you can end up with kidney problems as well as a host of other things.
Get that hawthorn berry and celery seed extract in you immediately though. You dont want to let it go for 3 weeks when you dont have to. Chances are you'll start feeling like crap from sustained high bp. I personally dont think I've seen improvement with hawthorn, but a lot of people seem to have good luck. However, I always fought BP issues on cycle until I found celery seed extract last year. That stuff is a miracle. Last time I used it at almost half a gram per day. That's more than most recommendations but seemed to be a great controlling level for me. Good luck brother. Phera is an AWESOME compound....maybe you should PM me and point me in the right direction - I haven't been able to find it for years.
