- Typical dose
- 5 mg
PI-022Research use only
AOD-9604
Modified growth-hormone fragment
A modified fragment of the C-terminus of human growth hormone (residues 176-191) studied for fat metabolism without the full growth-promoting effects of intact GH.

- Typical dose
- 300 mcg
PI-023Approved (see notes)
Cagrilintide
Long-acting amylin analog
A long-acting synthetic analog of the hormone amylin, developed for weight management and most often studied alongside semaglutide in the fixed combination known as CagriSema. It remains investigational.
- Half-life
- Long
- Typical dose
- 2.4 mg
PI-024Investigational
Survodutide
GLP-1 / glucagon dual receptor agonist
An investigational once-weekly peptide that activates both the GLP-1 and glucagon receptors, studied for obesity and metabolic liver disease (MASH).
- Half-life
- Long

Mazdutide
GLP-1 / glucagon dual receptor agonist (oxyntomodulin analog)
A once-weekly GLP-1/glucagon dual receptor agonist based on the gut hormone oxyntomodulin. It has been approved in China for weight management and remains investigational in other regions.
- Half-life
- Long
- Typical dose
- 4 mg
PI-026Research use only
5-Amino-1MQ
Small-molecule NNMT inhibitor (not a peptide)
A small-molecule inhibitor of the enzyme NNMT — not a peptide — studied mainly in cell and animal models for its effects on fat-cell metabolism and its potential to preserve NAD+.
- Half-life
- Not well characterized in humans
PI-042Approved (see notes)
Liraglutide
GLP-1 receptor agonist (acylated human GLP-1 analog)
Liraglutide is an FDA-approved GLP-1 receptor agonist marketed as Victoza (type 2 diabetes) and Saxenda (chronic weight management). It is a once-daily injectable analog of human GLP-1 modified with a fatty-acid chain that extends its duration of action relative to native GLP-1.
- Half-life
- Approximately 13 hours, supporting once-daily subcut…
- Typical dose
- 600 mcg
PI-043Approved (see notes)
Dulaglutide
Long-acting GLP-1 receptor agonist (GLP-1 analog-IgG4 Fc fusion protein)
Dulaglutide (Trulicity) is an FDA-approved once-weekly GLP-1 receptor agonist for type 2 diabetes and cardiovascular risk reduction. It is a fusion protein linking two modified GLP-1 analog peptides to a human IgG4 Fc fragment, which substantially extends its half-life.
- Half-life
- Approximately 5 days
PI-050Research use only
Adipotide
Pro-apoptotic targeting peptide (prohibitin-homing motif fused to a KLAKLAK apoptotic domain)
Adipotide (FTPP) is an experimental targeting peptidomimetic aimed at the vasculature supporting white adipose tissue. In preclinical studies it induced fat loss by triggering apoptosis of the blood vessels feeding fat. It is preclinical/research-only, with notable renal toxicity signals in animal work.
- Half-life
- Short in circulation
PI-060Research use only
SLU-PP-332
Small-molecule ERR agonist (not a peptide)
SLU-PP-332 is a small-molecule agonist of the estrogen-related receptors investigated as an exercise-mimetic candidate that increases oxidative metabolism and endurance in rodents. Despite being frequently grouped with research peptides, it is not a peptide. Evidence is preclinical with no human data, and it is not approved.
- Half-life
- Reported short systemic exposure in rodent studies
PI-061Approved (see notes)
Tesofensine
Small-molecule triple monoamine reuptake inhibitor (not a peptide)
Tesofensine is an orally active small-molecule triple monoamine reuptake inhibitor first trialed for neurodegenerative disease and later repurposed for obesity. It is not a peptide. It remains investigational and is not FDA-approved, though it produced notable weight loss in Phase 2 obesity trials.
