Test C  Testosterone Cypionate Super common especially in the US.

It’s just testosterone with a longer ester attached

Feels very similar to Test E for most people

Longer half life means fewer injections

Smooth steady levels if dosed right.

Often used for TRT and cycles alike

Slower release not slower gains.

Same hormone delivery timing is the only difference

Popular because it’s predictable and stable

Usually injected 1-2x per week

Less frequent pinning than propionate

Some say it feels softer than Test P subjective though.

Great option if you hate injecting often

Bloodwork timing matters more with long esters

Same benefits same risks as any testosterone
