So happy with my order!

I just got my Methylene Blue 0.5% Solution and a Glass Dropper Bottle from CZTL and I'm super impressed! The packaging was really secure, everything arrived in perfect condition. I was a bit worried about ordering online, but their website was easy to use and I got a confirmation email right away. It's exactly what I needed. I will definitely be buying from them again for my research needs. Really happy with the whole experience!

Good deal on Methylene Blue

I was looking for some Pharmaceutical Grade Methylene Blue and CZTL came up. I signed up for their newsletter and got that first order discount, which was nice. Ended up getting the Methylene Blue 1% Solution. Price was decent, especially with the discount, and it arrived faster than I thought it would. Felt like a good value for what I paid.

Consistent quality, reliable shipping

I've ordered the USP Grade Methylene Blue Powder from CZTL several times now. This last order was for a bulk pack. Same great quality as always, and it came with the lab reports which I appreciate. Shipping took about 6 days to get to my place in Texas, which is pretty standard for them. They're my go-to for this stuff.

any seasonal sales coming up? waiting for a good deal.

F Faith Carter 2 months ago

Black Friday and Cyber Monday usually have some good ones. Also around New Year's or Prime Day they might have something.

C Cody 2 months ago

Keep an eye out for holiday sales, they often do 10-15% off or sometimes free shipping promotions.

Is this stuff legit? There's so much junk out there, don't want to get scammed.

F Faith 2 months ago

They post lab reports for heavy metals and stuff, so that's a good sign. Mine came with a COA too.

W Wendy Whitfield 2 months ago

I've ordered a few times, never had an issue. The USP grade designation is a pretty big deal for quality.

hey, wondering about shipping times to like, New York City? need this stuff kinda soon.

N Noor 2 months ago

Mine got to California in about a week, so NYC might be similar? They ship from overseas though, so keep that in mind.

S Sarah Walsh 2 months ago

Yeah, I think for US orders it's usually 7-10 business days. Sometimes faster if customs doesn't hold it up.

Can I use multiple coupon codes at once?

M Mike Kaur 3 months ago

Nah, pretty sure you can only use one coupon code per order. That's standard for most online stores.

B Ben Hughes 3 months ago

I've tried before, it usually just takes the first one or tells you it can't stack. Bulk discounts are automatic though, which is nice.

what's the return policy like if I change my mind or something's wrong?

L Lisa 2 months ago

I think returns are only if it's damaged or incorrect, and you have to contact them pretty quickly. Check their site, but I recall it being a bit strict.

C Cody Z. 2 months ago

Yeah, unopened and unused within a certain timeframe. I've never had to return anything though, quality has been fine.
