At the beginning of my cycle I opened my bottle of Deca and bottle of tri test and pinned .75ml of each. Now the Deca was fine but soon after the tri test I had a lot of PIP and after a couple of days a large hard lump developed and seemed to be spreading across my right glut. No redness, little localised swelling and no heat. After speaking to my guy he said that the tri test sometimes doesn't mix properly wand if I put it in some hot water for 30 seconds and give it a shake this will re dissolve the test into the oil. I did this and all subsequent injections have gone fine. However, my only worry is that heating the oil my have denatured it in some way. Are my concerns correct and should I bin that bottle and buy a new one, or should I just crack on? Incidentally I opened my second bottle of tri test and pinned that and it was fine. Any suggestions guys?
