That's what I use. I switched from Kirkland's because it made my scalp itch, but it's very affordable. Lipogaine is more expensive, $25 each and I buy 12 bottles, but I prefer 24 bottles to use 2ml twice a day. It stopped my hairloss by itself, I started using it without the big 3, then I added the big 3 a month later. But honestly I haven't seen that much regrowth now using 2ml once a day, either that or it's been really slow, 11 months so far. Then again my before pics are in my damaged PC, my hair loss was pretty bad. I'm sure there has been some regrowth, it's just been so slow, like when you look outside in an airplane and everything is moving slow.
On another note, when I was using 2ml twice a day I was seeing more success, like my hairline and temples started growing little hairs and they actually kept getting thicker they didn't just stay like light hairs, and that was like with 3 months of use. Unfortunately I only bought 12 bottles so I couldn't keep up using 2ml twice a day. I will be adding a higher percent of minoxidil once a day too.
