What is a peptide? Explained simply.
No prior knowledge needed. We explain it with small, tangible pictures — simple enough that almost any kid could follow along.
A peptide is a chain of small building blocks.
Picture beads on a string. Each bead is a building block — an amino acid. A few beads make a peptide, a lot of beads make a protein.
Where does a peptide come from?
Your own body is constantly building small peptides — all by itself. You even know some of them by name:
See? Peptides aren't anything foreign. Your body makes plenty of them all by itself. Some are also rebuilt in the lab — as an exact copy.
What does a peptide do in the body?
A peptide is like a small messenger carrying a note. It fits exactly into one particular lock — the receptor. Like a key. If it fits, a signal goes out:
Signals like this have all kinds of different jobs:
With BPC-157, such repair effects have mainly been seen in animals. In humans it's not yet proven.
How sure are we of this?
Not everything is equally well studied. The fuller the bar, the more certain the research:
Can you just take peptides?
Often not. Some are only available with a doctor's prescription, some are banned in sport. That applies, for example, to:
Very important: Peptica sells nothing and never tells you how much to take. For anything health-related, the rule is: always ask a doctor.
Where do you get them — and what to watch for?
Peptica itself sells nothing. A good provider always shows these four things:
Peptica may earn a small commission via these links. It costs you nothing extra.
Short questions, short answers.
Are peptides legal?+
It depends on the peptide. Some are medicine and need a prescription. Some aren't approved as medicine at all, or are banned in sport. Every entry on Peptica shows you what applies.
Does Peptica sell peptides?+
No. Peptica is for reading only. We don't sell anything. Our partners are clearly labelled as ads.
Do you tell me how much to take?+
No. We give no amounts for personal use. For anything health-related, it's best to talk to a doctor.
What does "evidence" mean?+
Evidence means: how well is something backed up by studies? Green = well supported in humans. Yellow = animals only. Purple = just an idea. Grey = still open.
