cottosed oil is cloudy

[WATERLOGGED]

i bought a vial of cottonseed oil 2.5 mths ago,its supposed to be sterile oil, but it has a layer of white powdery substance on the bottom and when i shook it up it looked like a cloud suspended in it. does anybody have any ideas whats up ? is it alright ? how long is it b4 it gets rancid ?

Try putting it in a hot water bath for a few minutes to see if it clears up.

Definitely DO NOT USE IT. It is the most cheap component of the a good homebrew...but that doesn't mean it is not the most important! I prefer to get a fresh batch of oil everytime.

Hey Mr. Chemo, or other chem Guru:

Is Cottonseed the preferred oil? From the angle of lower viscosity (ease of push thru pin)? And is there any significant diff. in how much hormone can be dissolved in diff oils?

Thanks.

There isn't really that much difference in terms of how much a hormone will dissolve. Besides, you generally don't want to max it out as that most certainly will lead to painful injections. For cyps and enths stick to around 250 mg/mL. For acetates and props stay at or below 100 mg/mL (my preference is 75 mg/mL).

In term of viscosity, there are other oils that are "lighter" such as grapeseed. This does not equate to better though as most of the others tend to have preservatives which make for painful injections. IMO, it is best to stick with cottonseed or a high grade sesame.
