I have never tried Crinone but I have used both Utrogestan and Cyclogest vaginally and I can say that Cyclogest @50mg had zero side effects whereas 100mg Utrogestan vaginally was terrible. I didn't get on with 100mg Utrogestan every other day either.
Obviously there are exceptions but generally speaking, Utrogestan is not well tolerated and is the mostly frequently discussed problem on here. Most women do better with it vaginally but even then the side effects are significant. There is a school of thought that you can use a lower dose if used vaginally which makes sense but in my opinion, 100mg progesterone in one hit is too much and seems to cause side effects and knock out the beneficial effects of oestrogen. In my case, it triggered migraines.
This is just my personal opinion (again) but I think studies are only useful up to a point and should not be taken as gospel because they often conflict. The studies on HRT carried out in the early 2000s did far more harm than good and turned out to be deeply flawed. God knows how many years those studies set HRT back.
If you have problems tolerating progesterone, the only way around it is to take a sensible, tolerable dose ie 50mg ish vaginally and have regular scans to make sure you are getting adequate clearance/thinning. It's better and safer to have regular scans anyway because it picks up other conditions and checks ovaries, bladder etc. There is a chance that you will be unlucky and need a high dose of progesterone but it's far better to find out for sure than to keep guessing how much you need.
I would say Cyclogest is definitely worth a try.
