Leaving Sat to Riv. Maya Mex. Need info but maybe not what you think!

I'm back on G (5-6 wks.) after a break, using cjc. Use 2.5 to 3.3 iu/day for body comp, replacement and life extension (49 yrs old). The past few years I've taken just enough wth me to get by. No details, but I remove the metal ring. Packed in my checked bag. Pretty calm at check in as I work the night before and usually don't sleep well the before morning travel. Pretty sleepy!! Still, even a small risk is a risk. Will missing a week set me back THAT much?
Second, does anyone know if a couple of LEGIT vials can be had in Playa Del Carmen? NOT looking to score a substatial amount to bring back. 4th time in the area so I've got some lay of the land.
All insight/advice to either or both questions are greatly appreciated.
