Did anyone try Glucosamine Sulphate together with Supine Flexion?

Edit Post

Tyler from Naturalheightgrowth.com announced he had discovered a supplement together with Supine Flexion can increase your height even after your legs' growth plates are closed cuz your spine can still grow through spinal adjustion or something.
I'm human body blind so I can't say exact details about it.
But here is the proof:

I've tried this method for nearly 2 months but didn't gain any growth.I dunno why since it's got some scientific paper backgrounds,it wasn't still effecitve at all yet.

If you measure during night before you sleep, you should notice a few mm increase in height, because your discs likely retained more water.
You got ideas as the same as mine.I'm also thinking it's a fake story cuz Supine Flexion combined with Sulphate will only decompress your discs and after standing or sitting for a while,discal decompression will reverse.
