Every person’s body and health is very different, so everyone reacts uniquely. Hgh injections seem to be faster.
As for "beyond hgh" some people report noticing something after the first few days, some in a few weeks, and some not until the third month.

After 4 months many positive changes are quite noticeable. I was told the full benefits don’t show until the sixth month.
