Seems authentic and great bonding.
Yes - from India. Worked perfect for bonding an old dirt bike (KDX200) flywheel to an abused shaft. Bike has been driven enough to instill confidence in the repair. probably used 2% on this repair.

Works like it should. Made for India market so the label looks odd.
Worked like it should

This stuff makes a permanent bond.
This version of Loctite is a permanent metal sealant. To remove the nut or bolt you must heat. Great for applications that require a permanent solution (such as rivet nuts).

Good product for sealing threads
This stuff is amazing. I first learned about it when I was doing a mechanic's apprenticeship. I use it to seal threads permanently, where I don't expect ever to have to take that part off again. I've used it in environments where there is fuel and oil and it never disappoints or leaks for me.
