    Positive customer feedback.

    I was really excited to try these Creatine & Collagen Stick Packs, and the package arrived in great condition. I like that it comes with 20 packs, making it convenient for daily use. The taste is okay, not too sweet or sour, but it does have a bit of a tart flavor. I think the pineapple taste could be stronger and a little sweeter to balance it out. Overall, it reminds me of fruit punch juice and feels like a nice, easy way to support both fitness and skin health.

    Amazon Vine Customer Review of Free Product( What's this? )This combines the benefits of premium Creapure creatine and MoriKol marine collagen in one convenient stick pack. It mixes easily and offers a clean way to support both performance and wellness. The 5 grams of creatine help improve strength, endurance, and muscle recovery, while the added collagen supports joint comfort and skin elasticity, making this a balanced choice for active individuals.The flavor is light and pleasant, and the powder dissolves generally well in the water. However, some sweeteners are left even after mixing thoroughly. It is especially convenient for travel or post-workout use since each stick provides a precise dose with no measuring needed.This stands out for combining benefits for the brain, muscles, and beauty (skin, nail, hair) in one formula, though those looking for higher collagen amounts might prefer an additional supplement for that purpose.

    · Very Convenient: The single-serving stick packs are great. They are easy to take to the gym or on a trip. There is no mess from scooping powder from a big tub.· Good Mix of Supplements: I like that it mixes Creatine for muscle strength with Collagen for skin and joints. It feels like a more complete supplement.· No Stomach Issues: My husband says the Creapure Creatine in this product is very pure and does not upset his stomach, which he says happens with other brands.

    I really liked this! It dissolves easily and tasted way better than most collagen supplements I’ve tried — the pineapple punch flavor was actually enjoyable and not chalky at all. I can’t say much about the long-term results yet, but the ingredients look really solid (Creapure® creatine and MoriKol® marine collagen — both high-quality forms).What I loved most was the convenience. I normally take a different collagen powder that doesn’t come in travel size, so having these little stick packs was perfect for tossing in my bag or suitcase. They mix cleanly with cold water and are just so easy to use. Definitely something I’ll keep on hand for travel or gym days!
