The heating it will actually sterilize it, or at least the oven method will. The sauce pan might not get it hot enough. As far as after the heating, just remove from the heat then wait a few minutes maybe ten then remove the needle. Then just let it be. Don’t inject it when it is hot, it can be warm or slightly above body temp. Some guys like to inject it warm it’s another thing you can try. When I say warm, only a few degrees above body temp, like 2-4 degrees in C. Remember when you heat it then that needle is just letting air out, not sucking shit into the bottle. If you use the sauce pan method do not submerge the bottle, just have the base in the water, fill the sauce pan so it comes up about half way on the bottle and you will need to move the bottle around a bit so it doesn’t create a hot spot under it.
When the UGL makes any steroid they order raw powder from China. Well 95% comes from China, a little comes from Russia and India. So they have this powder but really it’s just super tiny crystals. The whole goal behind brewing it is to dissolve the hormone into the oil. Get it down to the molecule surrounded by oil. Sometimes just solvents can dissolve it but really it needs to be heated. Test enanthate has a melting point just above room temp so when they mix it with the solvents it is instantly a clear solution so many UGLs assume that is enough, it’s not. Just like when you mix sugar into hot tea (assuming your from a Great Brittain influenced place by your use of “mate”) the hot tea makes the sugar dissolve easier than cold tea.
When I say crashing that means the dissolved hormone reverts back into crystals form, it’s no longer fluid in the oil. If you stick in this world long enough you will get a bottle with tiny crystals at the bottom. A number of factors influence when and if the hormone will crash. Stuff like concentration, amount of solvents, carrier oil used, brewing techniques, storage techniques.
The theory behind it crashing once injected is the muscle instantly or quickly absorbs the BA and possibly some of the BB out of the solution and then without that being in the oil the oil can no longer hold the hormone in liquid form. Thus it starts to stick to the other hormone molecules and form crystals. Just like if you dumped a bunch of sugar into hot tea then it cooled down some of the sugar would fall out of the tea to the bottom of the cup forming a little layer of sugar.
If you are familiar with winstrol injectable it is actually just really tiny crystals suspended in a water based solution. In this case the crystals actually act as a kind of slow time release. People think the reason winstrol hurts to inject is because it is in water, I am fairly sure it is because no matter what you do it will always be in tiny crystals. So even if your shots are crashing you are still getting the hormone into your blood stream. It isn’t dangerous per say to be in Crystal form inside of your muscle but it could lead to issues if it goes on long enough.
With your test enanthate being 250 I bet the root of your issue would be it was not heated properly. I guess the UGL could have used a very low percentage of BB but even then if it was heated properly it would hold in the oil. That is if you are not one of those poor guys that just has sensitive tissue and gets PIP from everything.
One last technique to avoid PIP, rotate injection sites. Try to only inject a particular muscle once a week. I myself have run some cycles with a mix of compounds with some of them requiring every other day injections. I can re inject a muscle twice a week but I know it’s like playing roulette as far as it might decide to be a bitch and turn into a knot of pain.
If you turn out to just have ridiculously sensitive muscle tissue then you can explore subcutaneous injections but that will effect the traditional half life’s to some degree of most hormones.
