    Excited about peptides and hair / skin health

    I’m perimenopausal and have noticed some changes in my skin, hair growth and volume, so I’m always curious to try new things that might support my health. Hair growth peptides caught my attention, and the gummy form seems faster, easier, and tastier IMO. I love supplements that taste good, are easy to remember, and fit into my routine without a lot of fuss. These gummies have a nice raspberry/ wildberry flavor. They’re mildly sweet with a little bittersweetness and a slight vitamin taste. The texture is soft and chewy, and honestly, I enjoy taking them! I do refrigerate them for a firmer chew (my preference). I usually take them with my morning tea or afternoon smoothie, and I've even tucked some into my purse vitamin case for when I’m on the go (convenience is everything 😉). I’ve only been taking these for a little over a week, so it’s too early to say whether I’ve noticed any hair growth benefits, but the flavor and ease of use get a thumbs up from me. I feel like my skin and nails look and feel healthier, so that is a great sign. Anything that improves my health and makes my morning routine a little more fun and less of a chore is a win!

    No bad aftertaste

    So first of all, I have to mention that they taste good! Usually gummies have a bad aftertaste, but these gummies are extremely pleasant! They have a semi sweet taste which I enjoy so I def don’t mind taking them everyday. Also, I have noticed when I washed my hair recently, that it’s less hair shedding. It seems like my hair stands are getting stronger so I’m excited! Can’t wait to continue using the products and seeing my results.

    Surprisingly tasty!

    These are not like other gummy supplements I’ve tried that I dread taking because of the taste and long lasting after taste. These are surprisingly tasty, I feel like I’m stealing my kids gummy treats.

    DEFINITELY WORKING AT 6 DAYS AS IT CLAIMS

    I wouldn't write a review unless I was 100% certain and let me tell you, there is absolutely less shedding from within the first week! Just like Khloe says in her review on the commercial, there is without a doubt less hair in my brush after the shower and no loss in the shower at all. I'm not kidding or exaggerating. I am looking very closely and I mean not even a full week in I'm noticing the difference! Like 3 single hairs guys, versus a bunch normally when I'm detangling after the shower. I am ordering more so I don't run out!
