Well first congrats on your wife giving you the go ahead. An indecisive woman? I've never heard of such a thing

In the future, at least according to my doctor, free test is a more important clinical marker than total test. You could have all the test in the world, but if its bound by SHBG than it has no bio availability to the body. 550 would put total test in the middle range but not knowing your age and cycle history it's tough to say and as Bio pointed out, WHEN you run your labs is also very crucial in terms of time of day, as men's T levels peaks in the waking hours (think of that quickie you want even brushing your teeth). At least you know your baseline total scores as this will help to know your recovery after completing this cycle. Definitely get labs again (and remember to take note of free test and SBGH scores too). Do it all correctly and recover properly and she just may let you run another one...
