What each peptide is known for
A quick, natural explanation of why people talk about each peptide. Open any one for more detail, including its current status and important limitations.
Weight Management
Retatrutide
Known for: Weight management, appetite, and metabolic health
A newer option designed to work with three signals involved in appetite, fullness, and how the body uses energy. It is still investigational and is not approved for general use.

Tirzepatide
Known for: Appetite control, weight management, and blood sugar
Works with two natural gut-hormone signals that help with fullness, appetite, and blood-sugar control. It is used as a prescription medication under medical care.

Semaglutide
Known for: Fullness, appetite control, weight management, and blood sugar
Mimics a natural GLP-1 signal that helps people feel full longer, slows digestion, and supports blood-sugar control. It is a prescription medication.

AOD-9604
Known for: Fat metabolism and body-composition interest
A small piece of the growth-hormone molecule that is often discussed for fat metabolism and body composition. Evidence for everyday wellness use is limited.
Read the simple guide →Weight Management
Cagrilintide
Known for: Fullness, appetite, and weight management
Acts like amylin, a natural hormone connected to fullness after eating. It is being evaluated as a longer-lasting appetite and weight-management option.

Survodutide
Known for: Weight management, appetite, and metabolic health
Targets two signals tied to appetite, blood sugar, and energy use. It is a developing medication and is not a standard consumer wellness product.

Mazdutide
Known for: Appetite, weight management, and blood sugar
Works with GLP-1 and glucagon signals, which are connected to appetite, blood sugar, and energy balance. Availability and approval depend on location.

VK2735
Known for: Weight management and metabolic health
A developing option that targets the same two gut-hormone signals often discussed with tirzepatide. It is still in the medication-development stage.
Read the simple guide →Recovery & Healing
BPC-157
Known for: Recovery, tissue repair, and gut-health interest
Often discussed for tissue repair, gut support, and recovery after strain or injury. Most evidence is early, so human benefits are not established.
Read the simple guide →Recovery & Healing
TB-500
Known for: Recovery, mobility, and tissue-repair interest
A peptide fragment commonly associated with movement, flexibility, and tissue-repair signals. Most available evidence comes from early-stage work.
Read the simple guide →Recovery & Healing
KPV
Known for: Inflammation, gut comfort, and skin support
A very small peptide connected to the body’s inflammation response. People most often hear about it in conversations about gut, skin, and immune comfort.
Read the simple guide →Growth Hormone & Body Composition
Tesamorelin
Known for: Growth-hormone support and body composition
Encourages the body to release more of its own growth hormone. It has a specific prescription use and is also discussed in body-composition conversations.
Read the simple guide →Growth Hormone & Body Composition
Ipamorelin
Known for: Recovery, sleep, and body-composition interest
Sends a signal that may encourage the body to release growth hormone. It is commonly discussed around sleep, recovery, and body composition, but it is not approved for general wellness use.
Read the simple guide →Growth Hormone & Body Composition
CJC-1295
Known for: Growth-hormone support, recovery, and body composition
A longer-lasting signal designed to encourage natural growth-hormone release. It is often mentioned with recovery and body-composition goals.
Read the simple guide →Growth Hormone & Body Composition
Sermorelin
Known for: Growth-hormone support, recovery, and vitality
A shorter growth-hormone-releasing signal that encourages the body to make more of its own growth hormone. Medical supervision is important.
Read the simple guide →Growth Hormone & Body Composition
MOTS-c
Known for: Cell energy, exercise response, and metabolic health
A peptide linked to mitochondria—the parts of cells that make energy. It is being explored for energy use, exercise response, and metabolic health.
Read the simple guide →Aesthetics & Hair/Skin
GHK-Cu
Known for: Skin, hair, collagen, and appearance support
A naturally occurring copper peptide commonly used in skin and hair products. It is associated with collagen, skin repair, and healthy-looking hair.
Read the simple guide →Wellness & Immune Support
Thymosin Alpha-1
Known for: Immune-system support and resilience
A peptide connected to immune-system communication. It is used medically in some countries and is discussed for immune balance and resilience.
Read the simple guide →Sexual Wellness
Kisspeptin-10
Known for: Reproductive hormones, fertility, and sexual wellness
Works near the start of the body’s reproductive-hormone signaling chain. It is often discussed in fertility, hormone, and sexual-wellness settings.
Read the simple guide →Sexual Wellness
PT-141
Known for: Sexual desire and sexual wellness
Works through brain pathways connected to sexual desire rather than directly changing blood flow. It has a specific prescription use for certain patients.
