Testosterone propionate must be injected every 2-3 days, but testosterone enanthate (doses of 200-250 mg) and testosterone cypionate have longer durations of action and can be injected every 2-3 weeks, for replacement therapy of hypogonadism.
Propionate
This type of testosterone is a slow-releasing anabolic steroid with a short half-life of 4.5. allows users to run short Testosterone Propionate cycles in the range of 8 - 10 weeks, sometimes in as little as even 6 weeks.
Use of doping agents, particularly anabolic steroids, in sports and society. Significant anabolic effects occur at supraphysiologic testosterone levels (>1000 ng/dl), which generally requires weekly doses of 300 mg or more.
1 ml per week is 200 mg per week of testosterone. This is a replacement dose not shown to increase lean mass significantly in the short term. However, using higher doses may also increase red blood cell production and blood viscosity, so your doctor needs to monitor your hematocrit blood levels.
As expected, the shortest chained ester, testosterone propionate, showed the most rapid elimination and shortest half-life. Nevertheless, the ester could still be detected for 4-5 days in serum and plasma of all study participants receiving the drug.
Effects on sexual interest appear after 3 weeks plateauing at 6 weeks, with no further increments expected beyond. Changes in erections/ejaculations may require up to 6 months. Effects on quality of life manifest within 3-4 weeks, but maximum benefits take longer.
How to use Testosterone Cypionate Vial. This medication is given by injection into the buttock muscle as directed by your doctor, usually every 1 to 4 weeks. Do not inject this medication into a vein. Dosage is based on your medical condition, testosterone blood levels, and response to treatment.
If you injected 100 mg on at the beginning of the week and another 100 mg towards the end of the week, your peak isn't as high and your low isn't as low. Twice per week is preferred for the balance of testosterone delivery.
Testosterone propionate possesses a relatively short half-life compared with other testosterone esters at approximately 4.5 days.

Most individuals will start to notice significant changes within 4 to 6 weeks of beginning treatment with testosterone injections, but some changes may actually be felt and seen much earlier.
Increases in total testosterone of 1046 ng/dL (95% confidence interval = 1040-1051) and 898 ng/dL (95% confidence interval = 892-904) were necessary to achieve median increases in lean body mass of 1.5 kg and appendicular skeletal muscle mass of 0.8 kg, respectively, which were required to significantly enhance one-
The received wisdom is that testosterone must be injected weekly for at least 10 weeks. Yet sports scientist Robert Weatherby of Southern Cross University in Lismore, New South Wales, Australia, who conducted the study, found the biggest increase in performance came after just three weeks.
In general, the dosage is 50-400 mg injected into your muscle every 2-4 weeks. Dosage increases: Your doctor may adjust your dosage based on your testosterone blood levels, response to treatment, and side effects. Maximum dosage: 400 mg injected into your muscle every 2 weeks.
