Understanding Peptides

Peptides are small molecules made from amino acids, which are the same building blocks that make up proteins in the body. You can think of peptides as tiny messengers that help cells communicate with each other.

Inside the body, many natural peptides help send signals that guide how cells respond and interact. These signals are part of how different processes in the body work and stay coordinated.

Because of this, peptides play an important role in how the body functions at a cellular level.

Peptides are compounds naturally found in the body that support various functions. Below is a list of commonly known peptides and what they are typically associated with.

Growth Hormone / Muscle / Recovery

CJC-1295 (with/without DAC) – muscle growth, fat loss, better sleep, recovery
Ipamorelin – recovery, muscle building, sleep, appetite regulation
MK-677 (Ibutamoren) – increases GH/IGF-1, muscle gain, appetite, sleep

Fat Loss / Metabolism

AOD-9604 – targeted fat loss, stubborn fat areas
Tesamorelin – reduces visceral (belly) fat, improves body composition
GLP-1 (e.g. Semaglutide / Tirzepatide) – appetite suppression, weight loss, blood sugar control
Retatrutide – appetite suppression, significant fat loss, metabolic regulation (triple hormone action)

Brain / Energy / Longevity

MOTS-C – energy production, endurance, fat metabolism
Semax – focus, memory, mood, cognitive function
Selank – anxiety reduction, calmness, stress support

Healing / Recovery

BPC-157 – tendon/ligament healing, gut health, injury recovery
TB-500 (Thymosin Beta-4) – tissue repair, inflammation reduction, mobility
GHK-Cu – skin repair, collagen, hair growth, anti-ageing

Muscle Growth / Performance

IGF-1 LR3 – muscle growth, recovery, strength, nutrient partitioning
Follistatin-344 – muscle growth via myostatin inhibition

Immune / General Health

Thymosin Alpha-1 – immune support, illness recovery

PEPTIDE SCIENCE

How Peptides
work

Biological Lock and Key

Many peptides work by interacting with specific receptors in the body. A simple way to picture this is like a lock and key — the receptor is the lock, and the peptide is the key that helps trigger a signal inside the cell.

These signals are part of how cells communicate with each other and respond to what’s happening around them. This communication is what allows different processes in the body to work together.

How Peptides Are Different From Supplements

Peptides are different from vitamins or supplements. Supplements are usually nutrients like vitamins, minerals, or herbs that people take as part of their diet.

Peptides, on the other hand, are small molecules made from amino acids that interact with the body at a cellular level. Instead of acting like nutrients, they are better understood as messengers that help carry signals within the body.

Because of this, peptides are quite different from everyday supplements, as they are involved in how signals are passed between cells rather than simply providing nutrients.
