Best Peptides for Weight Loss & Fat Loss (2025) - Complete Guide

More and more people are exploring peptides for their potential applications in fat loss, metabolism, and energy management. But which peptides are most studied for fat loss? And what should you consider when purchasing them for research?

This comprehensive guide covers the best peptides for fat loss (2025), including mechanisms of action, research applications, and quality criteria. All information is for research purposes only and not for human consumption.

For high-quality research peptides within the Netherlands, more and more researchers are choosing Retalabs.nl because of transparent lab testing and fast delivery.

⭐ Why are peptides being studied for fat loss?

Peptides play a role in various biological processes, such as:

  • regulation of appetite
  • fat metabolism
  • glucose uptake
  • energy consumption
  • hormone balance

Many scientific studies focus on how certain peptides can influence these processes.

Below you will find the most researched peptides within fat loss in 2025.

🔥 1. MOTS-C – Research into metabolism and energy management

Status: Emerging rapidly (2024–2025)

Popularity: ⭐⭐⭐⭐⭐

MOTS-C is a mitochondrial peptide that is being studied in:

  • improvement of insulin sensitivity
  • increase in energy output
  • acceleration of fat metabolism
  • support for weight loss

In studies, MOTS-C appears to play a role in optimizing cellular energy production, which may indirectly support fat burning.

Why researchers find MOTS-C interesting:

✔ affects mitochondria (power plants of cells)

✔ popular in metabolic health research

✔ strong increase in global interest

MOTS-C is available through Retalabs.nl, where quality and transparent COAs are central.

🔥 2. CJC-1295 + Ipamorelin – Growth Hormone Pulse and Fat Loss Research

Status: one of the most popular research combinations

Popularity: ⭐⭐⭐⭐⭐

This combination is widely studied because:

  • natural growth hormone (GH) stimulation
  • improved metabolism
  • support of fat oxidation
  • better recovery and sleep quality

GH-related pathways play a role in lipolysis (fat breakdown).

That's why this stack is often mentioned in body composition research.

Why researchers use this stack:

✔ increase natural GH pulses

✔ lots of data from international studies

✔ synergistic effect

At Retalabs.nl researchers can obtain both peptides separately to design their own studies.

🔥 3. AOD-9604 – Fat Burning Research

Status: specifically aimed at lipolysis

Popularity: ⭐⭐⭐⭐☆

AOD-9604 (Anti-Obesity Peptide) is a fragment of the growth hormone molecule.

Scientific research focuses on:

  • accelerate fat breakdown
  • lipolysis stimulation without GH effect
  • targeting of stored body fat

Extensive literature describes AOD-9604 as a peptide of particular interest for obesity-related research.

Why researchers are looking at AOD-9604:

✔ no GH side effects

✔ purely focused on fat reduction in studies

✔ popular in obesity research

🔥 4. 5-Amino-1MQ – Research on increased cell energy

Status: trending in 2025

Popularity: ⭐⭐⭐⭐☆

5-Amino-1MQ is of interest for its role in research into:

  • inhibition of NNMT (a metabolic enzyme)
  • increased NAD+ levels
  • improvement of metabolism
  • faster energy consumption

In studies, this can lead to an increase in basal metabolic rate and improved fat burning.

Why researchers use 5-Amino-1MQ:

✔ strongly metabolically oriented

✔ influences cell energy consumption

✔ huge increase in popularity worldwide

🔥 5. Tesofensine – Not really a peptide, but extremely popular in fat loss research

Status: Extremely effective in clinical data

Popularity: ⭐⭐⭐⭐⭐

is not technically a peptide, but is often searched for in the same category by researchers studying fat loss.

Effects examined:

  • appetite suppression
  • increase in energy consumption
  • improvement of dopamine/serotonin balance
  • rapid decrease in body weight in studies
