Overview

The one genuinely approved pharmaceutical here (brand EGRIFTA), used to reduce visceral fat in HIV-associated lipodystrophy.

Additional research explores cognition and liver fat.

Mechanism

Stimulates endogenous GH release via pituitary GHRH receptors; N-terminal capping resists DPP-4 degradation.

Research

What the studies show

Meta-analysis of RCTs (HIV lipodystrophy)

Various · Systematic review · 2026 · Systematic review

Pools five multicentre RCTs; tesamorelin significantly reduced visceral and hepatic fat with a well-defined safety profile.

Tesamorelin and neurocognition in HIV

Ellis RJ, et al. · Clinical · 2025 · Clinical

In people with HIV and abdominal obesity, six months of tesamorelin showed a trend toward improved neurocognition, though not statistically significant between groups.

Phase II cognition trial

ClinicalTrials.gov (NCT02572323) · Clinical trial registry · completed · Clinical trial registry

Phase II study of tesamorelin for cognition in ageing HIV-positive adults; results posted 2024–2026.

Executive function in older adults

Baker LD, et al. · Clinical · 2012 · RCT

20-week trial in 152 older adults improved executive function in both MCI and healthy participants; the landmark cognition finding.

EGRIFTA SV approval + CROI 2025 CV-risk data

FDA / Company · Regulatory/clinical · 2025 · Regulatory/clinical

New long-acting formulation approved; company data questions BMI as a sole cardiovascular-risk marker in HIV.

Evidence summary

The gold standard of this catalogue: an FDA-approved peptide backed by multiple randomised controlled trials, with robust, well-documented effects on visceral fat and a growing body of research into cognition and metabolic health. The most rigorously evidenced compound here.
