SPECTRAL 5% UHP vs Kirkland Signature 5% both minoxidil any difference?

[findmyhair]

The site I get my minoxidil from has UHP available in 3 month supply and kirkland is now only in 6 month so i may switch as dont want 6 month supply incase i need to stop for whatever reason.

The ingredients are the same, has anyone tried the UHP is it any good?

Peace!
