Backfilling Syringes

Is there a consensus on backfilling syringes (2-3) at a time and letting them sit for up to a week? My concern is sterility (if that is a word) and if it is ok to leave the test in the plastic syringe for that time period. I tried it once with a mid week injection and it was faster to just pull the syringe and inject, needle is sharper, and fewer punctures of vial.

Any advice or input? Thanks.

I have done that when I know I have to be up and out the door at 4:15am, as I do three or four days in a row every month. It has never posed a problem for me.
 
Just a note of caution; the benzyl alcohol in the formula can melt the rubber stopper and leach chemicals out of the syringe. I wouldn't do it for more then a week at a time...not worth the risk of injecting bad shit into your body.
 
If you can control the orientation of the preloaded syringe could you put a cushion of Bacteriostatic Water between the oil based cypionate and the rubber plunger?
This would also solve the wasted Cypionate left over in the needle. Every drop counts right?
 
"just my two cents" I always put my testosterone vial, syringe and alcohol pad in a small bowl, and I put it on my dresser. When I get up in the morning I grab the bowl, walk into the bathroom and inject. It sure doesn't take very long.
If someone's in the bathroom, I'll inject right in my bedroom.
 
Thanks everyone for the input. Gene, your comment is enough for me to not do it. It was convenient, but drawing at the time of injection does not take that much longer and hopefully using the small needles the vial stopper and vial sterility is not compromised. I found articles that suggest that BA could attack certain types of plastic / rubber.

I make an effort to limit my exposure and intake of plastic leach by using glass or stainless steal for water bottles, food storage, purchased foods, coffee maker . . . I am not a fanatic, but try to reduced it compared to others by 80% or so. So much of the food is sitting in plastic for weeks or months. True for all chemicals I guess, just try to limit my contact/intake of chemicals and fumes. IMO, the human chemical exposure compared to 100 years ago is much greater when you think of all the chemicals in foods, lotions, medicine, water, and the air (inside and out). Again, not a fanatic, just make an effort when possible.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
