OK I am a master Bullshit artist, so here goes
Here is a list of other things besides AAS I have used syringes for, maybe depending on what kinds of stuff you are into one will work as an excuse
-I use a 3cc syringe and drawing needle to shoot that liquid rubber crap that you are supposed to use on the hanldes of tools (plastidip) into electrical connections on my Jeep top make them water proof
-Used it as a measureing device for G (not a good excuse)
-Shot B12
-Used it to measure very small quantites of pigment for making miniature doses of automotive paint
-Have used them for medicating pets, sedating roomate as well (does it hurt to sit suston?)
- Or worse comes to worse go get a bunch more pins and some 3/8 copper tubing at the hardware store. Take the plunger out of the dart, and cut the barrel roughly in half. Make about 6 of these things. Go to a room your parents havent been in lately and stick like half of them into an empty cardboard box. When your parents confront you about the darts they found in your glove bring them down to the basement and show them that they really are being used as darts, In your new homemade blowgun. BTW if you get the right pins and right pipe this fucking thing is like deadly
-You could also go to a vet store and buy some epiniphrine. Tell them you got the pins and epi in case of an allergic reaction to something less scary than AAS that you were taking orally, like some herbal shit that might give some folks a bad reaction.
-cross off the word cypionate on your sauce and change it to ciparo, and tell them you got it cause you are scared of anthrax
-I really liked the idea about the injecting booze. I might actually try that later today
-Just fucking lie if you think that wont be cool about it. I thought my parent were so old and stuffy, till one day when I was growing weed in the house and I came home from school to find my plants on the kitchenm table. All I got lecture on was that I cant grow dope in the house because it was illegal, and that my father never sold weed till he was in college. They took my lights away but not my plants, they told me to just get rid of them. So maybe they will be cool.
Good luck!!!!!!!
