Although Testosterone Propionate has a long half-life than the actual hormone, due to the fast dissociation and absorption in the body, one needs to keep on injecting themselves with the compound for maximum effects. The relatively shorted period of time that the steroid stays in the body, when compared to the other esters such as the Enanthate complex has several disadvantages but has disadvantages as well. One of the advantages of using the Propionate complex steroid is that it takes lesser time for the body to wash out and that makes the steroid a preferred choice for women and some athletes.
Some Vet companies as well as UG labs are now even producing 250mg/ml dosage vials. This dosage is more shocking than it sounds at first next to all the 250mg enanthate and now cypionate products in circulation. Testosterone propionate is less oil soluble than Testosterone enanthate or cypionate, making a high dosage more difficult to achieve. Before this the highest concentration you could find of this steroid was 100mg/ml. Reaching 250 milligrams is no doubt a result of not simply adding more steroid to one ml of oil, but increasing the alcohol content in the solution considerably as well. This makes for a much more uncomfortable solution to inject. Although admittedly the highest dose of propionate you will ever find, users have been reporting that it is also intolerably painful. Most find they have to dilute the solution with other lower dosed steroids if they are to continue using the product. This should be no a surprise I guess with a steroid that already has a reputation as being painful to inject.
