- VIP
- VPAC1, VPAC2 (G-protein coupled)
- Immune modulation via cAMP elevation; inhibits NF-κB, reduces pro-inflammatory cytokines (TNF-α, IL-6)
- Neuroinflammation, autoimmune models, vascular tone research
- <2 min half-life without stabilizers; requires immediate use or lyophilization with protease inhibitors
- Best for immune pathway suppression and neuroprotection. Not suitable for tissue repair or metabolic research
- BPC-157
- VEGF receptors, growth factor pathways
- Angiogenesis promotion, fibroblast proliferation, collagen deposition at injury sites
- Wound healing, tendon repair, gastric ulcer models
- 28 days refrigerated in bacteriostatic water
- Best for tissue regeneration and repair models. Minimal immune signaling impact
- TB-500 (Thymosin Beta-4)
- Actin-binding protein (not receptor-mediated)
- Promotes actin polymerization, enhances cell migration and wound closure
- Muscle injury, cardiac repair, endothelial migration studies
- Best for migration-dependent repair processes. Limited direct immune or metabolic effect
- Semaglutide
- GLP-1 receptor (incretin pathway)
- Slows gastric emptying, enhances insulin secretion, reduces appetite signaling
- Metabolic research, obesity models, glycemic control studies
- 5-day half-life; stable 28 days refrigerated in prefilled pens
- Best for glucose metabolism and appetite regulation. No immune or repair pathway activity
- GHRP-2
- Ghrelin receptor (GHSR1a)
- Stimulates pulsatile GH release, increases IGF-1, promotes lipolysis
- Growth hormone research, body composition models, aging studies
- Best for GH axis research and anabolic signaling. No direct immune modulation
- Semax
- BDNF, NGF pathways (synthetic ACTH analog)
- Increases neurotrophin expression, enhances synaptic plasticity and cognitive function
- Cognitive enhancement, neuroprotection, learning and memory models
- Best for neuroplasticity and cognitive research. Limited anti-inflammatory effect compared to VIP
