Half the lists circulating for health cheat contain entries from an older version that simply do nothing now.

Short answer

Enter them exactly as written, on the platform-appropriate input, and expect achievements to be disabled for that save.

Anything that requires downloading a program is not a cheat code. Case and spacing matter more than the lists suggest. If you are coming to this after a long break, the terminology has probably moved on.

Anything promising online effects

A code that softlocks a mission is a known risk in more than one of these games. Some effects stack in ways the developers did not intend and the game does not handle gracefully. Treat anything stated without a version number as provisional. Achievement locking is usually per-save rather than per-account, but not always.

Console entry uses button sequences with tight timing, and mistiming reads as a broken code. Where two approaches both work, the one with fewer moving parts is the one to keep. Codes typically do not persist through a reload, which surprises people who use them for convenience.

What you give up

GTA 5 is not shy about hiding useful information two menus deep, so some of this is simply knowing where to look. Do the cheap check before the expensive one — that ordering alone saves most of the frustration. The awkward part is rarely the step itself, it is knowing which step comes first.

  • Expect achievements to lock for that save file.
  • Save manually before using anything irreversible.
  • Expect one number in every guide to be out of date; the method is what matters.
  • Enter codes exactly, including spacing.
  • Ignore any list that asks you to install something first.

What each one actually does

What follows assumes you are on a current install and have not modified it. Anything that behaves differently on console than on PC is flagged where it matters. Screenshots age faster than text, which is why this describes rather than shows. A single check up front replaces a lot of guessing later.

The short version is near the top on purpose; the reasoning is there if you want to know why. None of this needs a paid tool, a third-party launcher or an account on a site you have never heard of. The community wisdom on this is roughly half right, and the half that is wrong costs the most time.

Codes that no longer work

If a step reads as obvious, do it anyway — the obvious ones are the ones people skip and then wonder about. The developers have changed their mind about this at least once, which explains the older advice. Patch notes move numbers around constantly; the shape of the answer holds even when a specific value shifts.

Half the pages on this topic were written for a build that no longer exists, which is why they stop matching what you see. It helps to understand why a step exists, because then you can adapt it when your situation is slightly different. If your result differs from what is described here, note what is different first rather than starting over.

How to enter them

Where something depends on your platform or region, that is called out rather than glossed over. Most of the disagreement you will find online is two people describing different builds. Everything below is framed around the current state of GTA 5 rather than a launch-week impression.

Where people go wrong

  • Changing five things at once and then not knowing which one helped.
  • Rushing the last step, which is usually the one with the actual requirement in it.
  • Skipping the prerequisite because it looked optional in someone else's summary.

GTA V FAQ

Why is a code not working?

Either it belongs to an older version, or the entry method differs on your platform. Both are common.

How long does this take?

Minutes if it goes cleanly, an evening if you hit the edge case in the caveats list. Neither is unusual.

Do the effects save?

Rarely. Most reset when you reload, which makes them convenience rather than permanent change.

Why do other guides describe this differently?

Most were written for an earlier version and never revisited. Compare the steps against what your build actually shows.

Work through it in the order above and health cheat stops being a question you have to look up again.
