Best Peptides for Fat Loss

Short answer

The only peptide-based medicines approved for weight loss are GLP-1 drugs such as semaglutide (Wegovy) and tirzepatide (Zepbound), prescribed with a clinician. Retatrutide is still in trials. Other peptides marketed for fat loss (AOD-9604, tesamorelin off-label, MOTS-c) have far weaker evidence. The table below ranks what people here talk about, not what works best. Peptide Confessions does not publish dosing, timing, injection or sourcing guidance.

What users report, not which one works

This order is community volume, then a sentiment score from the same published confessions. It is not a claim that one peptide causes more fat loss than another. Counted 14 October 2026 from published confessions only. No dose is listed.

A peptide is ranked when at least five published confessions name it and also use a fat, weight, appetite, or waist word. Sentiment is how many of those match a narrow wanted-phrase list, minus how many match an unwanted-phrase list. The rank is the on-topic count. Sentiment breaks a tie. On this date there was no tie, so the table order is the on-topic counts. A negative score means the unwanted list hit more reports than the wanted list. It does not mean the file is mostly complaints. The wanted list misses a lot of ordinary sentences.

The existing feed of weight-loss posts is peptides for weight loss. The class tag, which is not a single peptide and is not ranked here, is GLP-1.

Comparison

Reports is every published confession tagged with the peptide. On-topic is the subset that names the peptide and matches the subject words. The hub link on each name is also the confession list.

Retatrutide

331 reports. 168 are on-topic, the largest file here. 52 of those 168 match a scale figure, the phrase food noise, or the word waist. 41 match the unwanted list. Sentiment is +11. Across all 331, appetite, hunger, or food noise appears in 40, heart-rate language in 14, nausea in 10, fatigue in 6, and constipation in 4. A report can be in more than one of those.

#132 describes food noise going quiet. #55 describes nausea. The phrase tally for the whole retatrutide file is the retatrutide side-effect report. Hub and confessions: retatrutide.

Tirzepatide

92 reports. 49 on-topic. The wanted list matches 11 and the unwanted list matches 16, so sentiment is -5. The words nausea, nauseous, nauseated, and queasy do not appear in these 92. Vomiting appears in 1. Heart-rate language appears in 6. Appetite language appears in 10.

#668 describes 67 pounds on tirzepatide after a semaglutide stretch, then a later switch. That is one account. Hub and confessions: tirzepatide.

Semaglutide

37 reports. 25 on-topic. Wanted phrase 6, unwanted phrase 7, sentiment -1. The reports do not line up. #25 describes 52 pounds. #87 describes food noise returning after stopping, and weight coming back. #57 describes the weight returning. #298 names nausea, vomiting, and constipation, and also says the weight came off. #43 describes hair loss. #603 describes vomiting that continued after stopping.

Hub and confessions: semaglutide.

Tesamorelin

29 reports. 9 on-topic. Wanted phrase 3, unwanted phrase 5, sentiment -2. Three of the nine also name a GLP-1, so this is not a solo file. The notes that are about fat placement rather than the scale are #81 and #295, both waist rather than weight, and #211, which calls the belly-fat change slow.

Hub and confessions: tesamorelin. The next comparison is tesamorelin vs sermorelin.

Cagrilintide

6 reports. 5 on-topic. Wanted phrase 2, unwanted phrase 1, sentiment +1. All five also name retatrutide or tirzepatide. #734 says the scale started moving after cagrilintide was added to a GLP-1 that had not moved it. #668 pairs it with tirzepatide. There is no confession here that is only cagrilintide.

Hub and confessions: cagrilintide.

Named in fat-loss stories, not ranked

A peptide stays off this list when most of its fat-loss sentences also name a GLP-1 and the peptide itself is not in that class. Otherwise a stack tag would outrank a smaller fat-loss file.

MOTS-c has 34 reports. 10 use fat or weight language, and 8 of those also name a GLP-1. #90 says it did nothing for the scale and added miles to a run. #378 describes energy, then no sleep.

CJC-1295 and ipamorelin show up in fat-loss sentences about half the time next to a GLP-1. The note that repeats on their own pages is sleep, which is the sleep roundup and the CJC-1295 / ipamorelin stack. SS-31, GHK-Cu, and BPC-157 pick up fat words inside stacks. They are not ranked here.

How this ranking was counted

Counted 14 October 2026 from published confessions only. A confession counts toward a peptide when it is published and tagged with that peptide. On-topic also requires the text to name the peptide and to match at least one of: fat, weight, lbs, pounds, appetite, food noise, waist, hunger, hungry, calories.

Wanted phrase, inside that on-topic set: "lost", "down", or "dropped" plus a number of lb, lbs, pounds, or kg; or the phrase food noise; or the word waist. Unwanted phrase: nausea, constipation, vomiting, fatigue, heart rate or palpitations, diarrhea, hair loss or shedding, anxiety, reflux, or heartburn. A confession can match both. Sentiment is the wanted count minus the unwanted count.

Rank is the on-topic count. Sentiment is the tie-break. Peptides under five on-topic reports are not ranked. Peptides that are not GLP-1s are left off when half or more of the on-topic reports also name retatrutide, tirzepatide, or semaglutide. The hub badge is a stored count and can lag this join by a report or two. A word match is not a diagnosis, and it is not evidence the peptide caused the change. No dose is listed. This is not medical advice.
