Hey, I don't have a lot to offer as I'm a bit of a newbie but will tell you what I know in case it's useful, & if not, apologies & disregard.
I have emailed a company this week that starts with B & am not one hundred percent sure we're taking about the same - their logo has 4 parts & maybe they sell BM with a blue lid???
If this lines up, I emailed them (B with the 4 part logo) this week with a bunch of dumb questions about shipping etc & they immediately sent me an adobe pdf which I assume is full of the technical specs or a CoA or something - I have no digital privacy & was too afraid to open it. But they sent it immediately & that might put your mind at rest. And I don't know the differences in types of reagent & grades etc but from every single thing I've seen, it looks like the percentage is the important part. And I had planned to do both a blood test & aquarium test yesterday but only got the blood done before I was nearly busted - I'm not a child at home, I'm nearly 50 in an abusive relationship. I didn't want to cut myself as I was worried either I couldn't do it or the opposite, that I'd become a cutter - no judgment, just now is not the time to pick up new things…. Someone on here mentioned a diabetic lancing kit which I got & am thrilled with that choice. I got out 2 tiny white dishes. Put a little bit of SN in one - I think the rec is 0.1g but my scales don't go that low. And put a little bit of SN on a tiny piece of baking paper. I put a drop of blood into the dish with SN. And a drop of blood into the empty dish & poured in the SN off the paper. Both turned dark chocolate brown immediately. I hope at least some of this is useful… And may I ask a question of you regarding packaging please? - if we are talking about the same B with the four part logo, I also asked about the discretion of packaging (my hopefully legit DMC tell fibs on their packaging). I am in Australia & hope it wouldn't be an issue with customs & I'm not terrified of the government doing welfare checks like the poor UK people - but the B I spoke to said they only send to personal addresses, not to PO Boxes (which I don't have yet but was considering). When I asked about the discretion of packaging, they said they always put the logo on the packaging. And if it's the blue lid bottles, they look an awkward shape. My issue is my ex that I am stuck living with at the moment - I literally ran to the letterbox & got there seconds ahead of him & stuffed my SN up my shirt because it was flat packaging - if he gets to it first, he will use it against me - call crisis, tell lies to have me committed, blackmail me, anything - he literally went through my rubbish bin in front of me last night - so if we're talking about the same B & BM, can you please respond, either here or privately, & tell me if the outside packaging indicates what's inside & if the size or shape of it is distinctive or what I could say it was or anything like that??? I haven't fully decided whether to order from them - I don't have any other backup sources & it's freaking me out. I've long since missed my CTB date & may not have the time to order from a second source - but life has been throwing some extreme curveballs that have kept me here & if I find out I'll be stuck here longer, I will one hundred percent order from B & any other source that people wanna throw at me - prefs not the Indian ones because I know there's a tonne of stock shortages. Anything legit like a good lab. Anywhere that is happy to be discreet with packaging. Sorry for hijacking your post, I started trying to be helpful to you & then it took an ADHD turn & here we are…. so sorry
I was writing at the same time as @StevFabi was posting - my letters start & end the same with the same amount of letters. So I'm pretty confident we're talking about the same thing, & hoping it's the same as OP.
If anyone at all has answers about packaging, either now as in already received, or in the future if yet to receive, I'd be super grateful if that was passed on, either on this thread or in private. My questions are at the bottom of my response to OP. I posted my original answer, then saw @StevFabi response & tried to write a second & it sent as one so if this one merges as well, I'm very sorry. Very bad at this, sorry
