The only way I have found is by diluting it with MCT oil. I usually have to cut the 200mg/ml primo in half to tolerate it. With that prop, it's probably not worth it. End up injecting a half gallon of oil each week.

many people assume all PIP is caused by poor injection technique, when in reality there are multiple potential causes. If someone is using sound injection practices and only one specific product consistently causes pain, the product itself becomes a likely explanation.

For testosterone propionate specifically, several factors can contribute: The propionate ester itself. Testosterone propionate has a relatively high reputation for causing PIP compared with enanthate or cypionate. The shorter ester requires a higher concentration of hormone relative to the ester weight, and many peopel report more tissue irritation.
Solvent system. Underground labs often use different percentages of benzyl alcohol and benzyl benzoate . Higher concentrations can increase injection-site irritation.
Carrier oil. MCT oil, grapeseed oil, cottonseed oil, sesame oil, castor oil, and ethyl oleate all have different viscosities and tolerability. Some individuals tolerate one oil very well and another poorly. Concentration. A 100 mg/mL Test Prop may be very comfortable, while a 150-200 mg/mL preparation (200 primo as an example) from another lab may hurt significantly because it is pushed closer to its solubility limits. Manufacturing quality. Underground labs vary considerably. Poor filtration, inconsistent brewing practices, excessive solvents, or hormone beginning to crash out of solution can all increase irritation. Individual biology. Some people simply react more to certain carrier oils or solvents than others. Does warming the oil help? Yes, it canbut only modestly. Warming the syringe to approximately body temperature: lowers the viscosity of the oil, allows it to disperse a little easier, may reduce injection pressure.

However, it does not change: BA concentration, BB concentration, the carrier oil, the irritating nature of the propionate ester.

If the pain is due primarily to the formulation, warming alone often won’t solve it.

Techniques that can reduce PIP a little anyway Inject slowly (30-60 seconds or longer for 1 mL). Allow the alcohol to dry completely before injecting. Let the oil warm to body temperature. Keep the muscle relaxed. Massage very lightly afterward if comfortable for at least 30 seconds or more. Walk or lightly use the muscle afterward to help disperse the oil. Rotate sites frequently. Avoid injecting large volumes into smaller muscles.
What often works better than changing techniqu is that people often find relief by: switching to another manufacturer or underground lab, finding a preparation with a different carrier oil, using a lower concentration, switching from propionate to enanthate or cypionate if daily injections or just do what I do and suck it up
