Errr, if you're talking about genuine Loctite, don't use green! It's a bearing retaining compound and is very strong.

The most common ones are:

Loctite 222 (pink) - low strength threadlocker
Loctite 243 (blue) - medium strength threadlocker
Loctite 638 (green) - high strength bearing retaining compound

222 is pretty weak and not worth bothering with, 243 is perfect for bike use, and 638 is what you'd use to fit headset cups into a loose/ovalised head tube (for example).
