mem,  I also have a script for my HRT meds.   Were you able to obtain BOTH test and deca from your prescribing MD. ?
My doc would only prescribe test 

 ... I don't even think he knows what deca is 

.
What reason did you give for wanting the deca?  also what dosage and frequency did he prescribe for both?
My script is for 300mgs. of 200 mg/ml cyp. every 3 weeks... I do a little bit more 

, of course, but not much.
I wouldn't worry about carrying a prescribed medication if I were you.  If you travel by plane, though, the temperature where the luggage is stored is not within the recommended range and 
may alter it's effectiveness.
