Comparisons
Side-by-side research breakdowns to help you understand the differences between commonly compared peptides and supplements.
Recovery & Tissue Repair
BPC-157 vs GHK-Cu
Healing peptide comparison — systemic tissue repair vs skin regeneration and gene modulation.
BPC-157 vs TB-500
Recovery peptide comparison — mechanism, tissue targets, and how to choose between them.
KPV vs BPC-157
Distinct gut/recovery peptides — an anti-inflammatory α-MSH fragment vs a tissue-repair pentadecapeptide, and their different mechanisms.
TB-500 vs Thymosin Beta-4
Fragment vs full protein — TB-500 is the synthetic active fragment of Thymosin Beta-4, not a rival compound.
Metabolic & Weight Loss
AOD-9604 vs MOTS-C
Two distinct metabolic peptides — an hGH fat-loss fragment vs a mitochondrial-derived peptide, and their different mechanisms.
Berberine vs Metformin
Blood sugar comparison — AMPK activation, clinical data, cost, and when to use each.
Semaglutide vs Tirzepatide
GLP-1 comparison — weight loss data, FDA status, and head-to-head clinical trial results.
Semaglutide vs Tirzepatide vs Retatrutide
Three generations of GLP-1 peptides compared — single, dual, and triple agonist side by side.
Retatrutide vs Tirzepatide
Triple agonist vs dual agonist — weight loss data, mechanism, and FDA status head-to-head.
Growth Hormone
Performance & Energy
Cognitive & Nootropic
Longevity
Epitalon vs NAD+
Longevity comparison — telomere biology vs mitochondrial metabolism, evidence quality, and cost.
NMN vs Niacin
NAD+ precursor comparison — pathways, cost, flushing, and what the research actually shows.
NMN vs NR vs Niacin
NAD+ precursor triple comparison — pathways, cost, flushing, and 2026 head-to-head trial data.
