Higher concentrates usually come with a little sting brother. Anything that is "convenient" comes with a little price to payJust curious, will that test cyp 400 give major pip or any pip? I use test cyp 250 and it’s smooth no issues whatsoever. I’ve read here for example the higher test enathate concentrations start causing a lot of users pip. I like the idea of a higher concentration test cyp but not if it causes pip. I can stick with test cyp 250 if that’s the case.
Its usually a small amount and is tolerable...
