Injection pain: Why it happens / How to prevent it / How to cure

Landmark Nutraceuticals Co.,Limited | Updated: May 23, 2016

Ester-An ester is a chemical modification were a alkyl group or groups are added to increase circulating time of a steroid compound, which controls the release of the hormone into the blood.

For example,Testosterone Enanthate

“Testosterone ”in the chemical name is the hormone, “Enanthate ” is the ester attached to the hormone.The only difference between Testosterone Enanthate, Testosterone Decanoate and Testosterone Propionate is the rate of release of the hormone into the blood stream.

Short Ester- breaks down more quickly, requires EOD or ED injections. Examples

are acetate and propionate.

Long Ester- allows for a slower break down, therefore 2XW injections. Examples are Enanthate and Decanoate.

17aa- Changing (Alpha Alkalizing) a hormone’s seventeenth position from carbon to a double hydrogen (C -> H2). Also known as “Methyl”. This process protects the hormone through the first pass in the liver, allowing a usable amount of hormone to be left over. Examples are M1T (Methyl-1-Test) and M-Tren (Metrienolone).

Suspension- A non-esterfied hormone (Testosterone, no ester) or a 17aa that is

“suspended” in a liquid solution to be injected or swallowed. More commonly water based but can also be found oil based. The most common example is injectable Winstrol.Very painful due to fast release and also ED or 2XD injections are necessary. The advantages to using suspensions are the quick rates at which they enter the blood and are released from the blood, great for controlling exact levels and avoiding testing.


What causes (non infection related) injection pain?
1. The shorter the ester, the higher the melting point
2. The concentration of the gear.
3. The solvents used.
4. Tnjecting too quickly.
5. Virgin muscle.
6. Pain is caused when the oil/solvents are absorbed by the body and crystals are left behind.
7. Short esters (propionate or acetate) are harder, more painful crystals with melting points in the 100c range.
8. A hormone with a longer esters (excluding cypionate - cyp is long but also high melting point) can have a melting point in the 20c-40c range. not far off from human body temp.

9. If you inject too quickly it can tear tissue.
If your muscle is new to the hormone, it will absorb the hormone very slowly, but absorb the oil/solvent very quickly. This will cause more crystalization and pain. As your muscles recognize the hormones, they will be absorbed more quickly, thus less pain. The deeper you inject into the center of a muscle group, the better.

10. The solvents used can cause pain in 2 ways.

Benzyl alcohol (BA) is used at 1%-2% as a preservative and antiseptic. If the alcohol content is too high the gear will burn. Pain in the first 24 hours is usually caused by heavy solvents, pain in the next few hours is usually cause by crystalization.

Another way is a bad recipe. if someone used 2% BA, and the rest of the solution oil, the mg/mL would have to be low due to oil's weak ability to hold crystals. On the other hand, a recipe like 2% BA, 5% Guaiacol (super solvent), 10% Benzyl Salicylate (liquid asprin) with the filler split 50:50 between Ethyl Oleate (oil/solvent hybrid) and normal oil should be far less painful.


How do I prevent pain before I inject?
1. Cut your shots 50:50 with sterile filtered oil. If you want to use 50mg of Testosterone Propionate, and you have 100mg/mL Testosterone Propionate- pull 0.5mL of your test prop, and 0.5mL of sterile filtered oil to shoot 1mL of 50mg/mL Testosterone Propionate. This is the #1 best way.
Dont bother with b-12, its water based- absorbed so quickly it will have little to no impact.

2. Before you shoot, it can help to warm your gear some (especially suspensions). You could put the vial in the bathroom sink and let hot water run over the vial for 2 minutes, and shake well. This will lower the oils viscosity also making it easier it pull into the syringe.
3. Inject slowly, take 30 seconds per mL. Use a 25g pin to inject so it forces you to move slowly.
4. If none of these work you could have dirty gear. Its possible there could be particles (although bacteriostatic) in the gear that are not causing infection, but still cause in site infection that made it through a filter.

How do I deal with pain once I have it?
1. The worst thing you can do is ice it. Cold will help the crystals fall out of solution/suspension.
2. Its okay to take some ibuprofin to decrease the swelling, and help with pain.
3. Also being in a hot tub, or jacuzzi, or warm bubble bath will help melt the crystals down. Using a heating pad can help also.
