One thing is certain: the product is not certified. The certification listed on the packaging applies only to the facilities/method of production.

I didn't notice any difference. I finished it in a week and I won't buy it again because the price is prohibitive. It comes out to €120 per kilo.

It gives energy and is ideal for those who exercise as it also contains protein. I will definitely order it again

Light on the stomach, tasteless. I have started to feel better in my joints after a month and it doesn't hurt my stomach. My skin has started to become more radiant gradually. I recommend it.

The reason I started it was back pain and it has really helped a lot. However, the biggest difference is my nails, which are growing at an annoyingly fast rate, and my skin in terms of firmness. It’s probably only a matter of time before other positive effects appear. I am on the second box and the minus one star is for the price.

I have bought it twice because I was satisfied the first time. However, the second time its taste was somewhat different and I didn't like it. Since then, I haven't bought it again.

4 stars because I have only taken one box. I want to believe that by buying and taking more at the same time, I will see results.....

Collagen peptides work, but they require consistency.
The effective dose in most clinical studies is 10–15 grams per day — usually in the form of hydrolyzed collagen (collagen peptides) which is easily absorbed.

They do not "build" collagen on their own; however, they signal fibroblasts to increase production.
The first results are seen in about 6–8 weeks, while the full effect is seen in 3 months.

Combining with vitamin C and adequate total protein significantly enhances the result.

good product
but it arrived half inside

I don't know to what extent the supplement is responsible, but I have noticed differences in my skin and in the healing of small wounds (e.g. scratches from a cat)

I've been taking it for 1 month now so I haven't seen any results yet.. For its price, a big drawback is the quantity...

I don't know if it does what it promises. In any case, the results can only be seen in the long term. It is definitely overpriced for the quantity it offers.

The berry lemonade flavor is amazing! It reminds me of fruit jelly! It's perfect!!! If someone has seen results but with a different flavor, they will go crazy with this one!!

Odorless and tasteless, the collagen peptide powder. But guys, you who make all this, if you read the comments, ..since it's so expensive, at least fill the boxes to the top ..not halfway! It's a bit shameful!

This one has an AWFUL taste, which okay maybe gets a bit lost in the water.. still, it's very heavy on the stomach.. I took it before lunch and it hurt my stomach.. I think in general it's a bit heavy, I can't manage to use it!!

The product is very good, it doesn't smell at all and has a pleasant taste. It has helped me a lot with musculoskeletal pain in my knees in combination with exercise. Even on my face, I notice various improvements and greater firmness!

I used it for only 1 month. I didn't notice anything different. The quantity is a big downside. It's almost only half the box full.

I do not know its effectiveness with regular use because unfortunately I do not receive it daily, due to its unpleasant taste and smell. The solubility is relatively good.

I haven't used it as much as I would like.
Its taste is neutral, which means you can add it to any drink you want.

You can add it to everything, as it dissolves very easily. It has no taste. As for the results, I cannot give an opinion as I have used it very little. I will definitely continue to buy it!

I have been using it for about a month, clearer skin (although oiliness remains), faster wound healing, stronger nails. Less back and waist pain.

I have been using it daily for 1 year now, my nails are stronger but what impressed me is that within 3 months my eyelashes are twice as long as before and my hair has grown much faster compared to before. Of course, it takes time to see results but from what I have understood, it works and has helped me. However, my skin is the same as before. It is still interesting to mention that within this year, I haven't caught a cold even once. I am sensitive and usually have a weak immune system, I usually get sick in winter but this year it wasn't like that.

It healed my stomach and relieved me from heartburn, indigestion, and food intolerances such as chocolate, fried foods, dairy, alcohol, coffee, and others. After years, I can enjoy the foods I like without regretting it.
As for the beneficial properties on the skin, nails, etc., I noticed something, but mostly in terms of skin elasticity.
