Loryna: testosterone depletion side effects?

Hi there! I've bee on Loryna for about a month. This specific type of progesterone is a testosterone antagonist, so it's supposed to be GREAT at combatting stubborn acne....

But...I've also read that it can take a hit on sex drive.

I have noticed feeling very tired since starting, but not sure about the sex drive yet.

Any good/bad experiences?
