Just to update, I have made several transactions with Mario, including the most recent one, and I can still highly recommend him as your first choice
specialty reagent agent. He has always managed to excel in shipping time, packaging and quality of the reagents.FrenchChemist - 21-12-2022 at 05:14
It's already a tradition, another package arrived without a problem and before Christmas.
Thank you Mario, you are number 1 hereMathias94 - 2-1-2023 at 07:28
New chemicals delivered in excellent condition, very quick as well, thanks dave321 - 2-1-2023 at 11:59
how do i contact mario ? i may wish to do an order with him
he seems to be a good guy to deal witharkoma - 3-1-2023 at 05:47
Looks quite promising with thiourea, you have experience with this route before?
Unfortunately not, but I'm about to start exploring another area of chemistry, which is quite extensive, includes so many interesting compounds.
Thanks to Mario, I have everything I need and I can focus not on synthesizing simple chemical compounds but going a few steps ahead.
Needless to say, it's very convenient.
very very nice

Another order recieved in perfect condition thanks to Mario. Quick shipping and good contact gonna order for sure againDope Amine - 9-2-2023 at 21:27
I've known Mario for many years now. He has always been 100% reliable, honest and professional. If anything he's the one giving me grief for not
responding promptly enough rather than the other way around.
I have the utmost appreciation for the services he provides. In a world with so many shitty people that will let you down it is very special to have
a guy like Mario that you can rely on. FrenchChemist - 27-3-2023 at 05:39
Thank you Mario for I don't remember which one in a row but another successful transaction Invictus - 2-4-2023 at 22:16
Mario is the best vendor for difficult (nay, impossible to obtain) reagents for chemical synthesis, bar none. Completely professional, packaged well
and had no issues receiving my order.
Needless to say if I know someone who needs a reagent that cannot be easily obtained or synthesized economically, Mario is the only one I would
recommend they contact.
I am not a shill or in any way paid to do this. I have ordered from him and done TONS of successful chemistry with said reagents, and there isn't a
doubt in my mind that everything he has is the real deal and exactly as he says it is.Schleimsäure - 7-4-2023 at 05:43
Once more reliable delivery with good communication from Mario, recommended.FrozenSpool - 10-4-2023 at 23:08
My recent order with Mario was stellar - easy communications, fair price, and all around an extraordinary reliable vendor.lewke1980 - 17-5-2023 at 00:21
thanks Mario for another order and very fast shipping

Another order from Mario came through, will definitely be putting in another order soon enough!
Cheers! Chemi Pharma - 5-7-2023 at 21:26
Glad to can buy from Mario again after a long time. The goods were well packed and arrived fast. The best vendor at Sciencemadness, no doubt. I
recommend and will buy from him again in the future for sure.Raid - 26-7-2023 at 12:52
Is anyone selling Hydrogen Bromide? I also could use some DCM, I need a lot of it though, around 7L.lewke1980 - 24-8-2023 at 09:28
Thank you Mario for your professionalism once again, I will be back soon after the holidays
Bubbles - 8-9-2023 at 08:18
Mario was able to acquire a rare reagent for me and as always was quick to reply and delivered as promised. I'll be back mario! dome13 - 25-9-2023 at 10:10

Mario is the man, 11/10 A++++
Is Mario still in business?

Just looking some basic battery related chemicals and noticed that this thread is very current.
From my experience I answer: 100% yesNitrous2000 - 30-9-2023 at 09:17
thanks,
I've sent off an email to the address on here, but haven't heard from him.
I also sent a U2U

Another great experience with mario, good communication, rapid shipping, good product. Conure - 30-4-2024 at 11:06
Does Mario have some MoO3&WO3?nzlostpass - 5-6-2024 at 19:28
Mario is great. I lost contact with him after 2 years of being in the hospital/rehab center after an accident and he is honouring my purchase from
over 2 years ago! Obviously costs have changed and I am happy to reimburse him for any extra costs but just wanted to say he is a stand up guy and
honours his word. Thank you Mario.lewke1980 - 11-7-2024 at 05:10
Thank you for another successful transaction, 100% satisfactionMathias94 - 29-10-2024 at 00:57
