Customer Reviews
Super impressed with CZTL's packaging!
I was a bit worried about ordering Methylene Blue for Research online, especially in a bulk pack, but CZTL really nailed the shipping. Everything arrived super discreetly packaged, no weird labels or anything, and the product bottle itself was really secure inside. I've ordered from other places like Blue Brain Boost before, and sometimes things can be a bit loose. Plus, getting that automatic discount at checkout for the bulk order was a nice bonus. Definitely my go-to now.
Decent experience overall
I bought the High Purity Methylene Blue Crystals. The product itself seems to be high quality, and the included COA was reassuring. Shipping was a bit slower than I expected, taking about a week to get here, but it wasn't a major delay. The packaging was secure. I'd probably buy from them again, but hope for slightly faster delivery next time.
Smooth order, good quality solution
My recent order from CZTL was for the Methylene Blue 0.5% Solution in a glass dropper bottle. The ordering process on their website was straightforward and simple, didn't have any hiccups. It shipped out pretty quickly after I placed the order, and arrived well-packaged without any leaks or damage. The solution itself appears clear and consistent, just as described. I appreciated that they included the lab reports with the product documentation, confirming the heavy metal free status. It's working as expected for my needs. Overall, a solid purchase and a good experience from start to finish.
Great value on bulk powder
This was my first time ordering from CZTL. I was looking for a good price on bulk Methylene Blue powder, and their tiered pricing really caught my eye. I ended up getting a significant amount for a very fair price compared to other places I checked. The savings were definitely worth it, making the purchase feel like a smart move for my budget.
Got what I needed
Needed some Methylene Blue for Research and found CZTL. The website was easy enough to use. My order came in a few days, earlier than the tracking said it would. Everything was packed well. It was just what I needed, no fuss, no drama.
Absolutely fantastic quality!
Oh my goodness, I just received my USP Grade Methylene Blue Powder from CZTL and it's incredible! The purity is exactly what I was hoping for, and the lab reports were so easy to access. I'm genuinely impressed. This is exactly what I needed for my research. I'm definitely going to shop here again and tell all my colleagues about it!

Do they do a first-time buyer discount? Or any coupon codes floating around?
How does CZTL compare to, say, Science.bio? Thinking about switching suppliers.
Hey, wondering how long shipping usually takes to, like, California? Need to restock soon.
Can I use PayPal to pay? Or is it just credit cards?
thinking about getting the solution instead of powder this time. does it come in glass dropper bottles or plastic?
