It is actually the same stuff they use for training law inforcement. The only difference between it and the Crime Scene stuff is that this doesn't preserve the DNA. The tablets are mixed with water to activate it--so it can't be diluted unless you do it yourself--and it's suppsed to pick up 1 part blood in 1000 parts water if it rains. Would take a LOT of diluting to render it ineffective. As far as peroxide--does it glow in the dark? Doesn't peroxide also bubble when mixed with water (rain)?? Dump a little in your sink and see what happens...
The reason I'm interested is I'm colorblind and reds blend in with greens/browns. No amount of honing skills with help a physical handicap.
