I just got some test propionate in the mail, it had been sitting out in the cold. It sat on the table inside for about 1 hour at 70 degrees, i wiped the top sucked out about 1 cc and stuck it in my vastus. So, really no prep is what that is saying. Yea, I took a swab to the vial and injection site but no heating dancing around or anything like that.
Feels fine now, like after any IM injection to me (b12, morphine, dilaudid, antibiotics etc whatever). I don't get all the issues with the testosterone propionate unless it is shit and contaminated.
