Two or more amino acids are connected by peptide bonds, and the "amino acid chain" or "amino acid string" formed is called peptide. Among them, peptides composed of more than 10- 15 amino acids are called polypeptides, peptides composed of 2-9 amino acids are called oligopeptides, and peptides composed of 2- 15 amino acids are called small molecular peptides or small peptides. (The above content comes from Baidu Encyclopedia)
Peptides are not health care products, let alone medicines, so it is very important to choose peptides.
Peptides are not made by ordinary companies.
So the choice of peptide depends on the producer,
I recommend peptide biology.

Instead of the acid method or alkali method used by most enterprises at home and abroad, the polypeptide adopts a safer and more efficient biological enzyme digestion method, and innovatively uses the 6T biotechnology standard of biological directional enzyme digestion, which not only reduces the molecular weight of the polypeptide to less than 500 Daltons, but also realizes targeted and accurate enzyme digestion. And 500 dalton is the "golden demarcation point" for human epidermal cells to absorb peptides, which can reach 99.99% of the absorption rate of human epidermal cells, and it is almost the lowest molecular weight peptide product on the market at present. In other words, the smaller the molecular weight of the peptide, the more fully absorbed by the human body and the better the effect.
Near 20 17 bis 1 1, all peptides strive to create "pure powder, no additives, small molecules" below 500 daltons.
