I get mine done every 4 months or so, for me it's free because of work. Some times on cycle some values show that something is a little "off" but there has never been anything severe and when i'm off, it all bounces back in 3-5 weeks...
PS. If you are somewhat worried you can take one baby aspirin per day, it won't do anything negative that's for sure.
Should be doing this everyday regardless of whether you are on or not. Save yourself from a stroke or heart attack.
Supplements while on:
Liver protector
Cholesterol lowering product(i like sytrinol)
fish oil(should be taken on or off, minimum 4 grams daily)
BP lowering product(I like Hawthorn)
Baby aspirin
Saw Palmetto(whether on or off)
-----
cardio, limit sodium,water
If you're going to blast 4 grams a weeks you better get on pharma strength drugs otherwise the above should work well.
