Thread: Carrier oil info and shelf lives

A good carrier oil for homebrew steroid injections should be thin,clean,sterile,painless,lowin particulate matter,anallergic,and has good solubilizing ability.

EO =Ethyl Oleate. EO is a solvent, which dissolves the powder but its use is to thin the solution’s viscosity.It’s a thin and expensive oil, created from ethanol, and used as a rubber softener, solvent, and typically used by us as a base for steroid solutions. It provides smooth and painless injections, and will suspend compounds at much higher concentrations than just oil. (It will make 100mg/ml Prop completely painless…) And because it’s a solvent, it allows you to use less Benzyl Benzoate in your blends, however BA is still used to maintain sterility.

GSO =Grape Seed Oil.GSO is called the “carrier”.A much superior oil for injections, as opposed to cottonseed oil, but also has a shorter shelf life. It should be stored in a dark place, at room temp.

CSO=Cottonseed oil.It is very thick, and has trouble flowing through a small gauge needle. It’s just a byproduct of the food industry, so it is cheap and readily available.

Also some people Wesson soybean oil,corn,peanut oil,sesame oil, soy oil, and safflower oil,MCT oil,olive oil,etc.
There are some other carrier oils available like rice oil, apricot kernel, coconut, sweet almond oil, avocado, flaxseed, and watermelon seed oil.

What oil is the thinnest?
Castor – 297.0 thickest
Crambe – 53.6
High oleic safflower
Peanut – 39.6
Sunflower – 37.1
Grapeseed – 37.0
Sesame – 35.3
Corn – 34.9
Cottonseed – 33.5
Soybean – 32.6
Safflower – 31.3 thinnest

Some carrier oils have better shelf lives than others. For instance, grapeseed oil only has a shelf life of 6-12 months,Watermelon seed oil is extremely stable and has an almost indefinite shelf life.

I don’t see miglyol 840 on here.

So do you think them being in air right vials makes it lasts longer? I have gear that’s over a year old

Of course. It all depends on how you store it. It also contains BA and BB which will make it last longer. Probably up to a couple of years if you haven't poked a hole through the rubber.

Mct oil?

I have had pharmacutical Test with an expiration that was 3 years away so I would think it was good at least that long if it is using similaringredients. I have used gear that old with good results.

Oh theres many factors that affect shelf life I'm sure.

I believe this one is strictly in regards to the actual carrier oil themselves without the addition of solvents.

Yeah but ur talking about refined gear with preservatives in it.

This list is just for the carrier oils themselves
