It's thin, so easier to inject, better experience for those who don't know what's going inside their body, especially if you're new to injections, it's nice to be done with it in a second and not have to exert force through a needle sticking out your ass.
EO in general (not pharmagrade EO like
@Sampei pointed out in another thread) is cheaper than basically any carrier oil.
It's a solvent so the solution is less likely to crash.
On the other hand it increases pip and systematic imflammation in people to a high degree. To some it's just some pip, to some it's a legit concern. There are cases of people losing mobility in joints around the injected area for upto a week or even longer from imflammation.
There are people that would never know it was in it though, it is used in pharma products afterall, though thats not the same EO most likely, this has been discussed in more detail in other forums outside the underground section recently, I'm getting a fever so I'm not gonna search for it RN.
It's an allergen, so again, a certain percent of the population can't use it period.
It's just completely unnecessary.
A few percent is usually fine for most people and it's nice to have your gear not crash I admit, I'm just not sure it's worth making your gear unusable to a significant, though not large percentage of the population.
It's just unnecessary risk. If you've done gear with EO in it and didn't notice, shoot ahead, your gonna be fine. Enjoy the higher concentration and thinner oil. I prefer thicker oil anyways though.
