Peptides like Ipamorelin and CJC-1295 are growth hormone secretagogues (GHS)

Abstract: In the last two decades, many new peptides have been developed, and new knowledge on how peptides improve the skin has been uncovered

The Science Behind Retatrutide's Triple Mechanism Each of retatrutide's three receptor targets contributes unique metabolic benefits: GIP Receptor Activation: Enhances insulin secretion in response to food intake Influences fat metabolism and storage patterns Modulates bone metabolism and cardiovascular function Complements GLP-1 effects for improved glycemic control GLP-1 Receptor Activation: Stimulates insulin release while suppressing glucagon Slows gastric emptying to extend satiety Reduces appetite through central nervous system pathways Provides cardiovascular protective effects Glucagon Receptor Activation: Increases energy expenditure and metabolic rate Promotes fat oxidation and lipolysis Helps prevent metabolic adaptation during weight loss Balances the anabolic effects of insulin signaling This triple-action approach explains why retatrutide demonstrated remarkable results in phase 2 clinical trials, with participants experiencing up to 24.2% body weight reduction at 48 weeks [4]

Evaluating a longevity protocol meaningfully requires investing in the data

Absorption kinetics are similar across SubQ sites, but abdomen and lateral thigh offer the most consistent adipose depth (612mm) for reliable depot formation, while upper arm adipose is thinner and more variable
