whenever I used tren for precontest in years past, I felt like I was going to die when doing cardio. It always happened when I started using tren. Some other guys at my gym experience the same thing.
As far as to why transdermal over injections, sometimes in certain careers it would be a lot easier. When you are at work for 2 to 3 days at a time it makes injecting more difficult, and if you were to get caught with a dart you would be in the unemployment line. It would be a lot easier to have a squirt bottle in your shave bag and would not raise any eye brows if someone went through your bag trying to prank you. Lots of jokes get played at the fire dept
I see, in this case, I would only suggest that you pre-load syringes and keep them in your locked locker in a well hidden area and wait for the proper/ideal time during your shift to take a rest room break. If I pre-load, from alcohol wipe cleansing to pulling the needle out takes mere minutes, perhaps four. I can't speak out of certainty, and of course you have to do what is best for your career, but I can't envision a three day period when you are unable to take a magazine into the stall and have some private time, all while dedicating a very discreet portion of your locked locker to keeping your ready-jects in. Also... I have always been told by friends in the Sheriff's Dept that steroid usage and awareness runs rampant within every sect of public service. Better than standing under a ceiling fan pumping globs of unlabeled mysterious white lotion into your palms and giving yourself rubdowns and waiting for it all to dry before putting your clothes back on - that would raise eyebrows immediately, let along doing it like clockwork day in and day out.
Option 1: Take a 4 minutes restroom break during your 72 potential hours
Option 2: Explain to everyone why you are applying lotion incessantly to varying shaved parts of your body from a dispenser with no label that will either have a distinct odor, leave residue on your skin/palms, or stain your clothing if you don't walk around shirtless waiting for complete absorption (or all three)
