Good deal on Z-Stack

I was looking for some immune support and Zstack Canada had a bundle deal on Z-Stack. It made the price per bottle much better than buying just one. Shipping was quick enough, and it felt like a worthwhile purchase overall. Happy with the savings.

Decent experience with Z-Stack Kids

I ordered Z-Stack Kids and Vitamin C for my children a few weeks ago. The ordering process on the website was straightforward, no issues there. Shipping took about 6 days to get to my address in Calgary, which is acceptable. Everything arrived well-packaged. The product quality seems good, they are GMP certified which is important to me. I had a quick question about dosage, and customer support replied to my email within 24 hours. Overall, a solid experience and I appreciate the clarity on their certifications.

Love the Z-Flu and Z-Night combo!

I just got my Z-Flu and Z-Night order from Zstack Canada, and I'm so happy! I wanted to be ready for flu season and also improve my sleep, and these products are perfect. The website was super easy to navigate, and my package arrived faster than I expected. I really like that they offer these specific combinations. The Z-Night helps me get much better rest, and the Z-Flu gives me peace of mind. I'm definitely coming back for more, and I've already told my sister about them!

Does Zstack Canada offer military discounts? My brother is looking to buy some stuff.

B Ben M. 2 months ago

I've seen them advertise military and healthcare worker discounts before, so I'd check their site or just ask customer service.

B Beth 2 months ago

Yeah, they totally do. My husband got a military discount last time he ordered. Just look for it on their FAQ or promotion pages.

is zstack canada the same as the original zelenko labs stuff, or is it like a separate company?

C Cody Q. 2 months ago

It's the official Canadian distributor, so it's all legit Zelenko protocol stuff, just for Canada.

B Beth 1 month ago

They're basically the official store for those products in Canada. So it's not a knock-off or anything, same formulations.

How are the returns with these guys? Ordered a bundle but thinking I might want to switch to something else, dunno if it's a hassle.

A Anna 1 month ago

Returns were pretty straightforward for me. Just follow their instructions on the site, I had no issues.

J Jared S. 1 month ago

I haven't actually returned anything, but I've heard it's not too bad. Just make sure you're within their timeframe, usually like 30 days unopened or something.

Hey, thinking of trying Z-Stack for the first time. Anyone know if they do a first order discount or anything like that?

M Mike N. 2 months ago

Yeah, I think I got like 10% off my first order when I signed up for their newsletter. It just popped up when I went to checkout.

O Omar 2 months ago

They usually have something like that. If not a specific first-order code, sometimes they just auto-apply a small discount, or you can get a better deal with one of the bundles.

Just wondering about shipping. I'm in New York, will Zstack Canada even ship here?

G Greg T. 2 months ago

I'm pretty sure they do. I've seen people in the states talk about getting orders from them.

J Josh 2 months ago

Yeah, they ship to the US. It might take a little longer than domestic Canadian shipping, but they definitely send stuff down south.
