There’s been a lot of talk lately that coring is coming from the older stoppers, so I want to test this myself. For that, I’ll be using 18g, 20g, 22g, and 23g needles.
For context, my entire Primal stash is still completely unopened. I have Test C, Tren E, EQ, Primo E (last batch), Mast E (which I’d rather not sacrifice if possible), Deca, and NPP. I’ll start with an older batch that has the older stoppers and see if any coring shows up depending on needle size. If I notice anything concerning, I’ll report back.
