What has changed with the oils within the last year? I’ve used MTS for around 8 years, with next to no PIP whatsoever, and that’s using Sust 250, Test 300, Test Prop, Test 400, Tren A + E, EQ. Recently I’ve found lots of batches to have awful pip.

Test 400 went in the bin.
Sust 250 gave a hot burning sensation during injection with lip lasting over a week.
Test 300 is hit and miss every batch. Some are good, some are awful.

From reading on here, PIP is accepted when it shouldn’t be. it’s not part of “the game”. How can one vial be smooth and the next awful? How can it be smooth for years then awful all of a sudden.

Injection technique is fine, I’ve been pinning for years. But within this last year or so the product seems to have gone down hill.

Yes the high concentration oils will have a bit of pip, but a sust 250? Definitely not.
