I use the myristoyl mixed (1:1) with the peptide eyelash growth on my brows and lashes. Prior to using, I had patchy growth on my brows and shorter lashes with irregular length. I've used this product nightly for about 5-6 weeks and my brows have no more patches; they're filled in with hair and my brows look fuller. My lashes are much longer and are finally growing at an even length. Since I have a few gray strands in my brows, I do use a brow wand with color to match my brows. Use smallest amount possible. Works really well with the eyelash peptide.
