Maybe it's where they stored it, or maybe it's like u said it's the mct oil... Idk if there using the same supplier for mct oil or if they changed.... I have heard of labs switching supplier for there carrier oil and it having a slight tint to it then it being crystal clear they never mentioned a different smell or smell at all. Some brands of oils iv used before I could smell but it wasnt a bad smell just the normal... And Im pretty sure they don't use any eo or guaiacol . There really wouldn't be a point in test cyp... The only thing I can think is maybe they use it on test no ester or some other compounds and it was stored close to those. Cause as I'm sure u know MSG guaiacol usually smells and can make the whole place smell, or maybe it was stored close to a eo or guaiacol bottle they once used and have kept around... I'm not sure when I get some of there stuff I'll see if I also notice. I do think they are one of the better ugls around presently... I spoke to them yesterday or today I know they sent some products out for testing so they should be posted up soon. I know src testing doesn't go as far as customer testing does. But they have usually tested pretty good and also off customer blind sample tests, which usually matches there test reports.... They have been around for some time now too and I really haven't heard to many bad things other then that one issue which they corrected and I believe was an isolated incident....
How are u feeling on it or too soon to tell really?
