Pramlintide (Symlin)
Pramlintide is a synthetic analog of human amylin, a hormone co-secreted with insulin by pancreatic beta cells. It is FDA-approved as an adjunct treatment for type 1 and type 2 diabetes to help control postprandial blood glucose levels, delay gastric emptying, and promote satiety.
01Dosing reference
02Mechanism of action
Amylin Receptor Agonism
Binds to and activates amylin receptors located primarily in the hindbrain.
Gastric Slowing and Glucagon Suppression
Slows the rate of gastric emptying and suppresses inappropriate postprandial glucagon secretion.
Glycemic Control and Satiety
Reduces post-meal blood sugar spikes and promotes a feeling of fullness, which can lead to reduced caloric intake.
03Human evidence
Significant reduction in HbA1c and postprandial glucose excursions in patients with type 1 and type 2 diabetes.
Demonstrated in multiple large-scale randomized controlled trials that led to its FDA approval.
Modest but sustained weight loss observed in diabetic and obese patients.
Clinical trials evaluating its effect on body weight independent of its glycemic control benefits.
04Preclinical evidence
Demonstrated reduction in food intake and body weight in rodent models of obesity.
Animal studies evaluating the role of amylin agonism on energy balance and metabolic regulation.
Showed synergistic effects on weight loss when combined with GLP-1 receptor agonists or leptin.
Preclinical models exploring combination therapies for enhanced obesity treatment.
05What is known vs. unknown
- Synthetic analog of the naturally occurring hormone amylin.
- FDA-approved for use with mealtime insulin in type 1 and type 2 diabetes.
- Slows gastric emptying and suppresses inappropriate glucagon secretion.
- Promotes satiety, often resulting in modest weight loss.
- Long-term cardiovascular outcomes compared to newer GLP-1 receptor agonists are less established.
- The exact mechanisms of synergy with other weight-loss peptides (like leptin) in humans require further large-scale trials.

AOD-9604
AOD-9604 is a modified fragment of human growth hormone (HGH) that includes amino acids 177-191. Research indicates it mimics the fat-burning effects of HGH by stimulating lipolysis and inhibiting lipogenesis, without the adverse effects on blood sugar or tissue growth typically associated with full-length HGH.
MOTS-c
MOTS-c is a naturally occurring mitochondrial-derived peptide that plays a key role in regulating metabolic homeostasis and energy production. Research indicates it acts as an 'exercise mimetic' by activating AMPK, improving insulin sensitivity, and enhancing physical performance in animal models.
GLP3-RT (Retatrutide)
Retatrutide is an investigational triple hormone receptor agonist that targets GLP-1, GIP, and glucagon receptors. Clinical trials have shown unprecedented weight loss efficacy, surpassing dual agonists, by combining appetite suppression with increased energy expenditure.
