Deep Caverns Mutagens (spoilers)

Alright, I'm having a devil of a time with the mutagen "puzzle".

There are two mutagens I've not found - ( Echo-4 & Solis-1 ).

So, I can't help but wonder if those two mutagens have sequences that would be useful.

According to the wiki, those are each located as follows:

This mutagen reagent can be found inside one of the buildings in Hollow Earth. A wall must be destroyed to get inside.

.
Well, I've triple-checked basically the entire Deep Caverns, and as far as I know, I have destroyed every wall necessary to access every blocked off area (although not literally every single wall - which is not strictly necessary to get to everyplace - because multiple walls may gain access to a common area), and I still haven't found those two reagents.

I've even scanned for unmarked but destroyable walls; and well, I missed them if they exist.
.
My hacking and lockpicking are sufficient that I've opened the 130 & 135 containers; and they're not in them.

I have neutral access to both Cytosine Outpost & Talos Outpost; and in them I've checked those red-hand-marked containers that I can without getting caught - so, some but not all of them. There are rooms in each place that I haven't gotten into because I can't without being seen (which brings hostilities).

My questions are:

• Is the wiki correct? Or, like the mutagen compound sequence itself, are their locations randomized for each game?
• If it is correct, does anyone know specifically where they are?
• If it isn't correct, is it possible they're in those locations or containers I haven't accessed for reasons noted above?

Hmm... Well I do not know the location for each... mutagens are set.

what I can confirm is that all of them - i checked wiki - is definitely in DC.

and when I said "in DC" I mean - labyrinth, power station, caves, all and every shelf in the city area, labs and residential area.

I however cannot confirm that puzzle works, since I only went down there when puzzle apparently didn't work properly.

2. If you head north from Caerus Residential, it's the third building to your right. Right after the big intersection with the broken-down tunneler. The canisters are on a desk inside.

That's it!   I got 'em

But.. not quite exactly by finding them there.

Turns out, I haven't crossed north from Caerus to that zone in quite awhile (usually I head east or west from Caerus, then north), and I had a loot stash on the ground in Caerus right at that north transition that I had forgotten about (and overlooked in my triple-checks) - and they were in that stash! 

Thanks!
