Ethyl Oleate is a carrier. It is great for short esters like Acetate, Propionate and Phenylpropionate forincreasing concentrations of these esters without crashing.

Steroids Carrier Solvent
Ethyl oleate is used as a solvent for pharmaceutical drug preparations involving lipophilic substances such as steroids.It is a relatively new solvent in the realm of bodybuilding, EO is Oleic Acid with an ethyl ester. EO is an excellent solvent for lipophilic compounds in injectable preparations. Its oxidative stability helps extend the shelf life of compounds, and its low viscosity provides for easy injections.
EO = Ethyl Oleate. EO is a solvent, which dissolves the steroid 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.
Ethyl oleate is primarily used as a vehicle in certain parenteral preparations intended for intramuscular administration. It has also been used as a solvent for drugs formulated as biodegradable capsules for subdermal implantation) and in the preparation of microemulsions containing cyclosporinand norcantharidin.
Microemulsion formulations containing ethyl oleate have also been proposed for topical and ocular delivery, and for liver targeting following parenteral administration. Ethyl oleate has been used in topical gel formulations, and in self-microemulsifying drug delivery systems for oral administration.
Ethyl oleate is a suitable solvent for steroids and other lipophilic drugs. Its properties are similar to those of almond oil and peanut oil. However, it has the advantage that it is less viscous than fixed oils and is more rapidly absorbed by body tissues.
Ethyl oleate has also been evaluated as a vehicle for subcutaneous injection.
EO used for short esters
Ethyl Oleate is a carrier. It is great for short esters like Acetate, Propionate and Phenylpropionate forincreasing concentrations of these esters without crashing.
Many people feel that Ethyl Oleate creates painless injections while others don’t feel the same. I only would suggest Ethyl Oleate for short esters for reducing pain and increasing concentration.
You can use a 50/50 concentration of Ethyl Oleate and oil such as Cottonseed or Grapeseed to increase concentration of NPP to 200mg/ml without crashing.
Some people feel that isn’t all that it is cracked up to be as many long ester formula’s seem to crash. Also the other con is the cost of Ethyl Oleate.
For many the pain is reduced because Ethyl Oleate is thinner and has lower viscosity then say grapeseed or cottonseed oil.
Personally I don’t use Ethyl Oleate currently as I don’t see many benefits over cottonseed oil or grapeseed oil.
You could even consider a 50-50 mix of EO and GSO. EO makes the gear thinner and some suggest more painless. On the other hand, some guys don’t take well to EO and it causes them pain. EO also does harm to the plastic/rubber end of the plunger of a syringe so you can’t hold your gear inthe syringe for any duration of storage.
If you notice, there is a trend…generally long esters hold easier at higher concentrations and require less solvent (EO/BB) than short esters.
Side Effect
Some people are allergic to Ethyl Oleate.
