Teeth whitening advice

[Jow686]

Hi Ive done treatment on teeth whitening posted by @pneumocystosis.
Bought Hp 35% of Ebay, 48h after 1st session ive got doubts about this Hp and rn Im thinking its really Pc.
The results are still great but right after usage was another level Ive noticed same thing with whitening strips which also has weak Pc and Hp so low that is jfl.

I noticed same thing happend after both this method and whiteningstrips. They look great right after but after a while although just drinked water to results are worse.
Ive done 1st session (3*20) right after they were great but after 48h results were much worse (although Hp should work out for 48h so results should increase) so Ive done 2nd session (2h*20).
After this one it was a lot better even after 48h but the same week Ive done it, it dropped to same level as (1 month after).

So is chineese man fucked me and sold something diff or hp should react like this or Im just schizophrenic?
Is it safe to done other treatments with diffrent substance or with proffesionals after 1nd half month?

looks like the only thing that changed was the lighting and your teeth got a little bit stained between 48 after the 2nd one and the after 1 month one

not a really noticeable difference

mirin btw
