What causes injection pain

Noticed there is the odd post about site injection pain so the following is an edited cut & paste I dug up from the archives that might help explain some of the issues we can have with site injections.

Non infection related injection pain.

Causes -

- the shorter the ester, the higher the melting point

- the concentration of the gear

- the solvents used

- injecting too quickly

- virgin muscle.

Pain is caused when the oil/solvents are absorbed by the body and crystals are left behind. Short esters (propionate or acetate) are harder, more painful crystals with melting points in the 100c range. A hormone with a longer ester (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.

Pain is also caused by concentration of your gear. Further to the above, let's say it takes the body 24 hours to absorb 1mL of a certain oil/solvent blend, and 24 hours to absorb 50mg of Testosterone Propionate . If 50mg (or less) of testosterone propionate is in 1mL of that oil, this injection should be painless. On the other hand, if 100mg of testosterone propionate is in that same 1mL of solution, then after 24 hours the body will have absorbed 50mg and 1mL, leaving 50mg behind in the injection area, crystalized and painful.

Its better to shoot 3mL of 50mg/mL Testosterone Propionate than 1mL of 150mg/mL Testosterone Propionate . This is also why water based suspensions (Testosterone base/no ester, Winstrol ) hurt the most, water is very easily absorbed in the body.

The solvents used can cause pain in 2 ways. Benzyl alcohol (BA) is used at 1%-3% 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.

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.

How do I prevent pain before I inject?

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.

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 .

Inject slowly, take 30 seconds per mL. Use a 25g pin to inject so it forces you to move slowly.

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?

The worst thing you can do is ice it. Cold will help the crystals fall out of solution/suspension . Its okay to take some ibuprofin to decrease the swelling, and help with pain. 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.

ive used tren e that was 85% solid in the vial and never had any sight pain, interdasting.........

i no what ur saying bro but its not pain at the sight, its spread throughout most of the quad, im guessing that the oil has spread throughout, disolved the oil faster than the hormone and left the crystals scattered everywhere, it doesnt happen much, just sometimes.

i never had this issue with test enanthate so its def down to the higher melting point/absorbtion rate of the short ester, no pain no gain. Running out of stories to hide the fact im using lol. I dont play sport so i cant use the bung knee excuse lol

Exscuses:

1)Immune system is non exsistant hence the swelling and redness you might have noticed on certain parts of my body.

2)Nahhh..Its just skin irritation I get from foods I shouldnt be eating, its a dietery thing.

3) Had it since birth, it flairs up now and then.

4)Its a pimple not a injection site.

So your saying mix prop with 50/50? so if you were to be on 1g of prop per week you would be sticking 20ml into you? Thats alot of oil.

thats the problem using an added sterile oil but hey scar tissue is good for BBers :D Best mix with a low melting point oil like TestE. Unfortunately you have a double whammy when yr mixing Prop with TrenAce in terms of BA. Injection depth is another factor. Usin a 1.25" pin is recommended for those with enough muscle mass. Sorry gf that sort of rules you out :grin:

You only get this when the gear is too strong to stay in solution. Heating or baking it will only provide a temporary solution. You can add more BB to it not BA. It will hold it up but may reduce the strengthmarginally. However you need to know what you are doing & preferably be in a sterile environment. Crashing in the muscle is another issue. You generally cannot see the crystals in solution. Its just when the oil is dissapated in the muscle leaving the compound in minute crystal form or like the original powder.

hahaha i cant even say its from a leg workout coz they would both be pegged leg.

Got the exact problem at the mo also and its farken painful. Both my front quads, one i cant even bend my leg . But had no probs with the test en 250. No pain no gain i guess. Not keen to try delts though.

same bro, enanthate .. sweet as, prop = propionate peg leg lol, i do delts its not bad unless you try 2 change a light bulb lol

i personally reckon quads are a shocker, no matter the ester even with test e i was always limping round

i like them because 2 handed injections go so well. i did my delt yesterday and the syringe moves alover the place with my racing heart beat. i probably should get into glutes but that seems worse
