T-cyp from one pharmacy burns, other does not?

[MMarvel]

Started TRT 3 months ago. I'm on 160mg T-cyp weekly (divided into 2 doses of 80mg). For the past 3 months, I've been injecting subQ with Tcyp from Olympia pharmacy. Yesterday, I received my first subQ injection from Tcyp from Empower pharmacy. The Tcyp from Olympia always caused a burning sensation at the injection site, so I was expecting this with the Tcyp from Empower -- but to my surprise, no burning sensation. Felt very smooth. The oil seems thinner too. Both are T-cyp and both use grapeseed oil. Both are the same strength. Using same needle.

Does this mean anything, one way or the other? Just curious that supposedly identical medicines would have that different of a result regarding reaction.

It’s the concentration of solvents they use in the carrier oil ie benzyl alcohol and benzyl benzoate. Some labs use a higher concentration of solvents than others and it causes the pain you are experiencing
