HEAD-TO-HEAD COMPARISON
HCG vs XyostedHuman Chorionic Gonadotropin vs Testosterone Enanthate (SC auto-injector)
Verdict: Xyosted delivers exogenous testosterone directly; HCG is a gonadotropin used to preserve endogenous testicular function alongside or in place of TRT. These are not interchangeable; they address different points in the HPG axis.

Who should pick which
- Pick Xyosted if the goal is direct replacement of low circulating testosterone with exogenous androgen.
- Add HCG to a TRT protocol to maintain testicular volume and intratesticular testosterone for fertility support.
- Consider HCG when sc 2-3x/week (trt adjunct) fits the protocol cadence.
- Consider Xyosted when sc auto-injector weekly fits the protocol cadence.
