Solvents of Making Injectable Steroids Solution

When to homebrew steroids,we will use some commom solvents and compounds,such as BB,BA,GSO and other solvents.Each solvent and compound have their special effects with less side effects.Here is going to list some general information about these solvents.

Benzyl Alcohol (BA):Sterilizing Agent

Main function for our purposes is keeping a solution bacteriostatic and dose prevent the bacteria’s growth.It’s presence as low as 0.9% is enough to prevent practically all microbial growth in solution.It’s also one of the thinnest(that is best for viscosity reduction).The shorter the ester,the more BA is needed to get the compound to dissolve.More BA is required to make high concentration products.

Major drawback: is that it tends to make for painful injections if the concentration goes above 10%.Less than this is painless for most people.

Benzyl Benzoate(BB): Solubilizer


A co-solvent that serves several functions: helps dissolve the hormone, helps keep it in solution in depot (injection site), and thins the gear so it is easy to draw and inject.

It is not nearly as strong and much heavier than the benzyl alcohol so benzyl benzoate is used primarily for its latent affects in the depot. Namely it helps keep the hormone in solution at the injection site after the more water-soluble benzyl alcohol has leached from the depot. benzyl benzoate is constructed of two benzene rings bridged by a carbonyl group, this making the solvent extremely hydrophobic. It is also painless at low levels and nearly painless at 15-20% for most people.

Grape Seed Oil: Carrier


Grape seed oil is much thinner,has anesthetic qualities,repairs damaged tissue and it actually healthy for you.It’s cheaper,more sterile,less allergenic than other oils.

Ethyl Oleate (EO):Carrier

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.

It provides smooth and painless injections and will suspend compounds at much higher concentrations than just oil.For many the pain is reduced because EO has the advantage of lower viscosity than the vegetable or seed oils and greater solubilizing ability.It also allows you to use less BB in your blends.

It’s great for short esters,acetate,propionate,phenylpropionate.

Drawback: EO does harm to the plastic/rubber end of the plunger of a syringe so you cannot hold your gear in the syringe for any duration of storage.Also EO is expensive.

Propylene glycol

is made ether from glycerol reacted with NaOH or from propylene reacted with chlorine and s carbonate,it’s not very toxic. This shit is used for everything. It is one of the lightest polyhydric alcohols.

Drawbacks: include discomfort injecting at high levels and poor viscosity for the MW. Not the most compatible with oil.

Polyethylene glycol (PEG):

is a polymer made for ethylene oxide. It comes in almost any MW, from 200 to 60,000. 400 to 12,000 are the most common with 400 the most common for liquids and 2,500 for solid. (Anything over 800 to 1,000 is a solid at room temp.)

It is nontoxic at any reasonable level. It’s great for getting things to stay soluble in oil. Used a lot for compatibility reasons. Can also be used as a painless vehicle, instead of oil.

Drawbacks: include high viscosity and thermoplastic tendencies becoming more pronounced at the higher MWs. Also has mechanical properties (surface tension) that cause it to separate from oil.


It is not a great solvent for the home brewer for a couple of reason. First and foremost do not inject glycerol undiluted. It is a strong dehydrogenating agent and can cause ruptures in cells. (OUCH) Oral it can even be taken as a diuretic. The second is that it is a very viscous solvent. It’s hard to thin. Can be used as a vehicle instead of oil.

Guaiacol: Super Solvent

A strong solvent pure and simple it has some water miscibility to it and high degree of oil solubility as well.Guaiacol is called super solvent,as with most high mg gear it contained guaiacol as a solvent used to create high level of concentrate.

It can dissolve powder more easily,and mainly used for oral steroids such as Oxandrolone,Dianabol,Winstrol,anadrol,etc.

Be very careful when brewing this if you use an open flame as your heat source,because Guaiacol is a combustable compound, so i would suggest everyone have a good hotplate with automatic, magnetic stirring if you regularly homebrew though.

Reduce Pain: Guaiacol has been shown to have anesthesic properties, though to what extent I can’t comment personally on. This fact is probably why solutions in high concentrations using the super solvent are reported to be painless or nearly painless by users.

Drawbacks: Though Guaiacol is a super solvent we seldom use it because it causes side effects which many people don’t like,such as:Allergies,Irritability,Fever,Cough,Disgusting vomits……

It has been shown to have irritating properties on inhalation, injestion, or skin contact in high quantities. It permeates the skin barrier very readily and will be distributed systemically as well.
