So this one instead of the Kirkland brand. It's basically the same thing right.

I can’t really speak to efficacy beyond its expiration date but I read here about someone claiming that they had diminishing results after using the same bottle (for oral) for around 8 months, I believe.

In addition to oral, I’ve started to also use my bottle topically a few nights per week just so I can avoid using the same bottle for more than a couple months.

And not sure if there are shipping restrictions where you live but I often buy Amazon’s house brand minoxidil.

But still 30$ for a 6 month supply is a steal. Minoxidil doesn’t have to be any brand so long as it’s minoxidil, all minoxidil is made the same

It looks like it's currently out of stock, but Amazon's brand Basic Care has Minoxidil 5% made by the same manufacturers of the Costco Kirkland Brand, Perrigo. I am about 1 month into a 6-month supply and it is slightly sticky like gel when applied in the morning, but no issues when I apply it at night.

Edited to add, I paid about $28 for a 6 month supply of the Amazon brand, but saw Kirkland Minoxidil was about $45 for a 6 month supply at Costco.
