Customer Reviews
Easy to order, arrived fine
Needed some Methylene Blue for research. Found CZTL online, the website was simple to use. Ordered the 0.5% solution. It showed up a few days later, no issues. Everything looked good and it was what I needed. Pretty straightforward.
Consistent quality, fast shipping
This was my third time ordering Methylene Blue Solution from CZTL. Like my previous orders, the 1% solution arrived quickly, and the quality was exactly what I expected. It's good to know I can rely on them every time.
Amazing Methylene Blue powder
Got the High Purity Methylene Blue Crystals and they are fantastic! The packaging was secure, and it arrived super fast. I'm really happy with the quality and the COA documentation gave me extra confidence. I'll definitely be buying from CZTL again, and recommending them to my research colleagues. A great find!
Good product, minor shipping delay
I bought the USP Grade Methylene Blue Powder. The product itself is very high quality, and I appreciated the included lab report confirming the heavy metal testing. Shipping took about 7 days to reach me in California, which was a little longer than I hoped, but still acceptable. Overall, a solid experience with good value.
Detailed review of my CZTL purchase
I recently ordered the Methylene Blue Bulk Pack (50g powder) along with a set of Precision Measuring Spoons. The ordering process was smooth, and I received an immediate confirmation email. Shipping took 6 days to get to my address in Texas, which was within the estimated timeframe. The packaging was very robust, with the powder sealed in a durable, opaque pouch, and the spoons individually wrapped. I also received the Certificate of Analysis via email, confirming the purity and heavy metal testing, which is crucial for my work. The powder dissolved easily and showed no signs of clumping. I haven't needed to contact customer support, so I can't speak to that, but the overall experience from browsing to delivery was professional and met all my expectations for a specialized product like this.

Hey, thinking of getting some of the Methylene Blue powder from CZTL. I'm in Chicago, how long does shipping usually take to get here?
Are these guys legit? I've seen some other MB suppliers online but CZTL pops up a lot. Just want to make sure I'm not getting some fake stuff.
