Compound profiles
RETATRUTIDE
Triple agonist research peptide (GIP / GLP-1 / glucagon)
Retatrutide is an investigational multi-receptor agonist studied in metabolic research for interactions with GIP, GLP-1, and glucagon pathways. Published human studies and newer late-stage trial updates focus on body weight, glycemic markers, cardiometabolic endpoints, and tolerability.
- GIP / GLP-1 / glucagon signaling
- Metabolic research models
- Appetite and energy-balance pathways
- Body-composition endpoints
TIRZEPATIDE
Dual incretin agonist (GIP / GLP-1)
Tirzepatide is a dual GIP and GLP-1 receptor agonist. FDA-approved products containing tirzepatide have specific clinical indications, while research-grade material should be discussed only in lawful research context and never as an informal treatment substitute.
- Incretin signaling
- Glucose regulation pathways
- Metabolic syndrome research
- Appetite and satiety models
WOLVERINE BLEND
BPC-157 / TB-500 blend concept
Commercially, “Wolverine” often refers to blends containing BPC-157 and TB-500. These compounds are widely discussed in tissue-repair research, but high-quality human evidence remains limited and regulatory status can differ by jurisdiction.

- Repair-signaling pathways
- Inflammation and recovery questions
TESAMORELIN
Growth hormone-releasing factor analog
Tesamorelin is a synthetic growth hormone-releasing factor analog. Approved tesamorelin products have specific labeled uses; research discussions focus on GH-axis signaling, IGF-1 response, body- composition endpoints, and metabolic markers.

CJC-1295 NO DAC
GHRH analog research compound
CJC-1295-related compounds are studied as growth hormone- releasing hormone analogs. “No DAC” versions are discussed separately from albumin-binding DAC forms. Research interest centers on GH pulsatility, IGF-1 response, and recovery-related biomarkers.
- GHRH receptor signaling
- GH release dynamics
- IGF-1 response models
- Recovery biomarker research
CJC-1295 + IPAMORELIN
GHRH analog + ghrelin receptor agonist concept
This blend concept combines a GHRH-pathway compound with a ghrelin receptor agonist concept. Research questions typically examine complementary GH-axis signaling rather than disease treatment or performance claims.

- Metabolic endpoint planning
- Lot-specific traceability
LIPO-C + B12
Lipotropic ingredient profile
Lipo-C + B12 products are typically discussed around lipotropic nutrient ingredients and vitamin B12 context. Because formulations vary, research documentation should identify each ingredient, concentration, sterility expectations, and storage requirements.
- Ingredient-specific documentation
- Nutrient metabolism research
- Formula comparisons
- Stability and labeling records
MOTS-C
Mitochondrial-derived peptide
MOTS-C is a mitochondrial-derived peptide investigated in metabolic homeostasis, insulin sensitivity, AMPK-related signaling, stress responses, and mitochondrial function. Evidence includes cellular, animal, and emerging translational research.
- Mitochondrial signaling
- AMPK pathway models
- Metabolic homeostasis
- Insulin sensitivity research
AOD-9604
Growth hormone fragment research peptide
AOD-9604 is a modified fragment derived from the C-terminal region of human growth hormone and has been studied in fat-metabolism and adipose-tissue research. Evidence is mixed, and it is not presented here as a treatment or dosing guide.
