The inner sealing tape was damaged (open). Unfortunately, I opened the outer tape without knowing it, and when I saw the inner one, it was already too late. I had to open it with video recording. Shake the packaging before opening the outer sealing tape, and if you see minimal dust, it means that the inner one is damaged.

I dissolve it along with the protein!
I saw results from the 2nd week in the weight I lift.
Just like that.
No side effects in the 2 months I've been taking it!

I did not notice any issue with its solubility or taste, as I drink it together with my protein. Overall, it is a very good creatine and the best value for money.

Very good, I saw results in the first 10 days. The negatives are the taste and it dissolves difficultly, but these are nothing compared to the results it has!

Excellent product, after a year of use (5g daily), I noticed a tremendous change in my muscle energy, increased and improved brain concentration, better mood, speed, and many other positive effects.
Each body reacts differently to keratin, we do not all have the same dosage limits, so try your limits, always in moderation.
Inform yourself before deciding to purchase it.
And rest assured, it is a harmless product if used correctly.
As for BioTech, what can I say? The best company out there.

One of the best products that someone could get, regardless of the proteins that are loaded with sugar. Especially for me, who has an issue with gaining weight, I have gained several grams within a week.

Good product and at a good price. I purchase it regularly and in the same way as before the pandemic.

The only creatine I have tried that dissolves amazingly in lukewarm water!
Also, I am familiar with some biotech products and trust them as a company.

Update: After almost two years and having used creapure creatines, which are considered the best and purest in the world, I have to say that biotech's is a very good choice!
