- Semaglutide (GLP-1 agonist)
- GLP-1 receptor activation → enhanced insulin secretion, delayed gastric emptying
- Moderate. Reduces fasting insulin by 25–35%
- Caloric deficit via appetite suppression + improved glucose disposal
- 1.0–2.4mg weekly subcutaneous
- Best first-line option for PCOS with confirmed insulin resistance and BMI >30. Strongest clinical evidence for weight reduction.
- Tirzepatide (GLP-1/GIP dual agonist)
- Dual receptor activation → superior insulin sensitivity vs GLP-1 alone
- High. Reduces HOMA-IR by 40–50%
- Caloric deficit + enhanced lipolysis via improved insulin signaling
- 10–15mg weekly subcutaneous
- Superior to semaglutide for metabolic correction in PCOS. Higher cost, stronger effect.
- MK 677 (growth hormone secretagogue)
- Ghrelin receptor agonist → pulsatile GH release
- Minimal direct effect. May worsen insulin sensitivity acutely
- Activates hormone-sensitive lipase → visceral fat oxidation
- 10–25mg daily oral
- Effective for visceral adiposity and lean mass preservation. Requires GLP-1 co-administration to offset appetite stimulation.
- Thymalin (thymic peptide)
- T-cell modulation → reduced IL-6, TNF-alpha
- Indirect. Inflammation reduction improves receptor sensitivity over 8–12 weeks
- None. Anti-inflammatory effect creates better environment for fat oxidation
- 10mg intramuscular daily for 10 days, cycled
- Adjunct only. Does not produce weight loss independently. Supports other interventions.
- KPV (anti-inflammatory tripeptide)
- NF-kB inhibition → suppressed cytokine cascade
- Indirect. Reduces hypothalamic and systemic inflammation
- None. May restore leptin sensitivity, allowing other pathways to function
- 500mcg–2mg daily subcutaneous
- Experimental. Best suited for PCOS cases with elevated CRP and confirmed leptin resistance.
