Not true. i have gear that is blended with a mixture of oil, solvents and ethyl oleate and it doesnt effect the plunger at all. i have also used test prop @ 1.5 cc and added 1.5 cc of pure ethyl oleate to the syringe and let it sit for a week (traveling) and it didnt effect it.
To the thread, its alright to pre load syringes, like maybe a 10cc vial of test prop, test suspension, basically short esters because you will be using it ed to eod anyways so it saves the hassle. if youre using long esters like test e, shootin twice a week, then it may not be a good idea. ive done both but only because i wanted to see if the vials measureout and they didnt (10cc had 8, 20cc had 16, right on the line). whatevers more conienent
Well there are well known sources that have posted not to do this on their site because the BA oil does eat the plunger. No I have never seen it because I wouldn't risk it.
