I have Test E from some major UGLs, so I don't think this is specific to one UGL. Every other injectable they have doesn't give me PIP, but Test E, without fail, makes the injection site hurt 12 hours later. There is zero PIP following the injection, but I feel like there's a rock in my asscheek if I do a standard medical intramuscular injection in my glutes.

This is a problem because it makes running more than 600mg/week test difficult during blasts. 800mg/week was the most I could bear with the PIP.

As far as I know, there are two ways to do this:

1. Heating the vial

2. Filtering it

I'm skeptical toward both of these, because I know the melting point for Test is so low. Also, I'm pretty sure these UGLs filter their stuff already.

What are my options here? I do have some spare millipore filters. Would it be worth a shot to filter them?
