Who should pick which

Switching between the two

Switching between testosterone formulations is typically dose-equivalent on a milligram basis. Adjust the cadence to the new ester's half-life: weekly for cypionate or enanthate, every 10 weeks for undecanoate, every 3 to 6 months for pellets.

Controlled substance. Testosterone esters are Schedule III in the United States. A valid prescription from a DEA-registered prescriber is required for any clinical use.
