I did a little experiment using canola oil and let it sit for a few days. There was no visible sign of deterioration or leaking.
I've got another cap filled with S4 right now seeing how it holds up, anyone see any issues pre storing these in caps?
On a side note I wish I ordered something smaller than 00 horse suppositories, I'm pretty good at taking pills and deep throating bananas (no homo DSM) but these things feel like they stick in your throat.
So advice, use smaller caps. If you take like 200mg than still use smaller just more of them. Unless you like big pills of course.
