what is that difference here guys? i see the same name like BLUE BOY or RUSH in the same bottle has TWO formula! because before when i got the poppers box it says Isoamyl now it is saying the other\ did they change it around?

There is zero difference. Isopentyl and Isoamyl are both a 5 carbon branch and identical. The real name is Isopentyl Nitrite (CH3)2CH-CH2-CH2-) CAS 110-46-3 Isoamyl is an outdated term and not used. I am not sure why it would appear on any bottle.

AMYL RUSH did exist once. You would have to be now in your mid to late 80s to have ever seen that. Hassing (Locker Room) replaced it with BUTYL, then Rush Brands in San Fransisco followed the lead. Poppers today do not contain amyl, whether they be Rush, Jungle, Amsterdam or whatever. You say that you wonder why an easily misumderstood name like isoamyl would appear on a bottle? I can think of one very good reason, the same reason that many newbie manufacturers put the word AMYL in the brand! This is because people wrongly think the poppers from their youth were amyl, they were not, they were butyl. I accept that there might be a few guys in their late 80s who might have been around for the very short period that Rush contained amyl. The same goes for UK, because PWD Rush were the biggest there in the 1980 period, not Jungle Juice (which was amyl then).

I'm 63 and I experienced Amyl RUSH in it's heyday in the 1970s and I've been sniffing ever since.
Twisted Beast Have an Amyl Rush as well as various Pentyl and Isopropyl + Amyl Mixes of the RUSH Brand
They are called GOLD RUSH (Amyl), RUSH Gold (n-Pentyl), RUSH BRUT (Pentyl), RUSH COPPER (Isopropyl + Amyl Mix),
There is also a RUSH with Butanol
NONE of them compare to the RUSH of the 1970s though.

"Amyl" Rush is a brand name only. It does not contain amyl nitrite, it cannot. It is misleading. They also do not have "Isopropyl + Amyl Mix" either. It is actually Isopropyl (the cheapest, nastiest popper, and a potential source of retinopathy) and pentyl (which has been cunningly re-labelled as ISO-AMYL) ISO-AMYL is NOT amyl nitrite, it has a different structure.

>There is also a RUSH with Butanol

Butanol is not a nitrite, it has zero effect except perhaps as central nervous system depression. It is something found in a wide range of commercial products, like paint stripper and other things, it is NOT a volatile nitrite, therefore why mention it? Wait...BUTanol...BUTYL...again misleading. Butanol is not BUTYL NITRITE lol ...original RUSH in the 1970s was Butyl, unless you were buying copy cats (then possibly amyl as they did not have the same scrutiny)

Congratulations on being 63, but you should familiarize yourself with FACTS ONLY. The last amyl nitrite was made by Locker Room. You will not find any in Europe, and certainly not the UK! You will also not find butyl nitrite in EU/UK either. Butyl was the original PWD RUSH. 1970s: possibly you enjoyed some bathtub knockoff that was indeed amyl, because they used it in snappers around 1970s (glass vial).

One other small FACTUAL point I just noticed. What year in the 1970s did you first purchase poppers? From where, an adult book store? which state if possible?
