Weight Loss Peptides 2026: 10 Options for Different Goals — From GLP-1 Plateau to Visceral Fat

Peptides don't replace Mounjaro or Ozempic. They work differently. And that's exactly what makes them interesting for those already on GLP-1 therapy but want more.

GLP-1 drugs block appetite. This is a symptom. Peptides correct metabolism at the cellular level. This is the cause. And when you understand this difference, it becomes clear why a combined approach can deliver results unattainable with monotherapy.

This article is a navigation guide through 10 weight loss peptides. Without hype. With real data. And honest "buts" where the evidence base is still forming.

What are weight loss peptides and how do they differ from GLP-1?

Peptides are short amino acid chains, typically from 2 to 50 units. They act as signaling molecules, triggering specific biochemical processes in cells. Unlike GLP-1 agonists, which work mainly through appetite receptors in the brain, weight loss peptides affect different links of metabolism.

Important to understand: none of the peptides described in this article have FDA approval for weight loss [5]. The only exception is Tesamorelin, approved for reducing visceral fat in HIV-associated lipodystrophy [37]. This doesn't mean peptides are ineffective. It means their evidence base is still forming.

What does this mean practically? If you're on Mounjaro and have reached a plateau, or want to preserve muscle mass during weight loss, or have a problem specifically with visceral fat — peptides can become that additional tool that's missing. More details about DOZA weight loss program and available options.

Summary table: 10 weight loss peptides

Now let's examine each in detail.

MOTS-c: mitochondrial activator for those who are stuck

MOTS-c is a 16-amino acid peptide encoded not in nuclear DNA, but in mitochondrial DNA [21]. This makes it unique: it literally is a message from the "power stations" of the cell to the rest of the organism.

Interesting fact: MOTS-c levels in plasma and muscles increase during physical exercise in humans [5]. This indicates that the peptide is part of the body's natural signaling system for exercise. A study showed that in obese Chinese boys, MOTS-c level was 20.3% lower [7].

For whom: if you're on Mounjaro or Ozempic and weight has stopped dropping, MOTS-c can help "unlock" metabolism. Especially relevant for people 35+ with signs of insulin resistance.

Typical dosage in studies: 10 mg per day. More details about MOTS-c in the peptide catalog.

Important "but": human clinical trials of MOTS-c are still ongoing [16]. Evidence base is forming, but we don't yet have large-scale RCTs in humans.

5-Amino-1MQ: NNMT inhibitor for visceral fat

Strictly speaking, 5-Amino-1MQ is not a peptide, but a small molecule [5]. But it's included in this review due to its mechanism of action: it blocks the NNMT enzyme in adipose tissue, which dramatically changes fat cell metabolism.

Why is NNMT important? This enzyme slows down fat cell metabolism and reduces NAD+ levels — a key molecule for cellular energy [34]. When NNMT is blocked, fat cells "wake up" and begin burning energy more actively.

What's important to understand: no human clinical trials of 5-Amino-1MQ have been published [34]. All data is from preclinical studies. Doses used in the community (50-150 mg per day orally) are based on extrapolation from animal models [33].

For whom: people with visceral fat (that same "beer belly") who want to add a tool to GLP-1 therapy. Visceral fat goes away faster than subcutaneous when NNMT is inhibited. More details about 5-Amino-1MQ.

Ipamorelin: selective growth hormone stimulator

Ipamorelin is a 5-amino acid peptide from the GHRP (Growth Hormone Releasing Peptides) class. Its key advantage is selectivity: it stimulates production of endogenous growth hormone without affecting cortisol and prolactin [20].

Why is this important for weight loss? When you're on a caloric deficit (which GLP-1 drugs create), the body may start "eating" not only fat but also muscles. Studies show that a larger proportion of patients on tirzepatide lost more than 5% muscle mass compared to semaglutide [9].

Typical dosage: 200-300 mcg before bed. The biggest growth hormone release happens at night.

Important warning: FDA included Ipamorelin in the Category 2 list of substances that may pose significant safety risks [28]. Concerns relate to potential immunogenicity and impurities. Serious adverse events, including death, have been reported with intravenous administration for gastric motility improvement [28].

For whom: people 35+ with muscle mass loss on GLP-1 therapy. But only from a reliable source and under specialist supervision. More details about Ipamorelin.

CJC-1295: synergist for Ipamorelin

CJC-1295 is a GHRH (Growth Hormone Releasing Hormone) analog that extends Ipamorelin's action by approximately 40%. Separately it's less interesting, but paired with Ipamorelin it creates synergy.

The mechanism is simple: Ipamorelin "asks" the pituitary to produce growth hormone, and CJC-1295 maintains this signal longer. The result is a more stable GH level throughout the day.

Like Ipamorelin, CJC-1295 is in the FDA Category 2 list [29]. This means compounding pharmacies in the US can no longer legally manufacture it.

More details about CJC-1295.

Tesamorelin: the only FDA-approved option for visceral fat

Tesamorelin (trade name EGRIFTA) is a synthetic GHRH analog with 44 amino acids [44]. And it's the only peptide in our list with FDA approval, though for a specific indication: reducing visceral fat in HIV-associated lipodystrophy [46].

Two key phase 3 clinical studies (LIPO-010 and LIPO-011) included 816 HIV-infected patients [37]. Results:

• Visceral fat decreased by 10.9% in the first 26 weeks
• Those who continued for 12 months — reduction of about 18% [46]
• IGF-1 levels significantly increased

Dosage: 2 mg per day subcutaneously.

For whom: people 35+ with a problem specifically with visceral fat ("apple"-type obesity). Especially if standard weight loss doesn't reduce waist circumference proportionally to overall weight loss. More details about Tesamorelin.

Why is the Mounjaro price justified? This is an original Made in UK product from Eli Lilly with full quality control and DOZA specialist support at all stages of the program. More details about cost.

HGH Fragment 176-191: selective lipolysis without growth effects

HGH Fragment 176-191 is a 16-amino acid fragment of human growth hormone that contains only the part of the molecule responsible for fat burning [1]. Without growth tissue effects, without IGF-1 elevation, without insulin impact.

Mechanism: the fragment stimulates lipolysis (fat breakdown) and inhibits lipogenesis (new fat formation) through beta-3 adrenergic receptors on fat cells [4].

Clinical trials of AOD-9604 (modified version of the same fragment) included about 900 participants in 6 phase I and II studies [4]. Safety results were positive: no serious adverse events, no immunogenic reactions, no changes in IGF-1, glucose or insulin. But weight loss efficacy was modest and inconsistent between studies [6].

Dosage in studies: 250-500 mcg before bed or fasting in the morning.

For whom: athletes on "cutting" who want to preserve muscles and accelerate loss of specifically subcutaneous fat. But expectations should be realistic — effects are modest.

BPC-157: GI protection during GLP-1 course

BPC-157 (Body Protection Compound) is a 15-amino acid peptide isolated from gastric juice [31]. Its main function is protection and restoration of the GI tract mucosa.

Why is this important for those on Mounjaro or Ozempic? The most common side effects of GLP-1 drugs are specifically gastrointestinal: nausea, vomiting, diarrhea. And this is exactly where BPC-157 shows itself best.

Important: animal studies of BPC-157 show positive safety profile without toxicity even at high or repeated doses. Lethal dose is not established in animal models [31]. But human studies are extremely limited, and FDA has not approved this peptide.

Dosage: 250 mcg × 2 times per day.

For whom: everyone starting GLP-1 therapy who wants to minimize gastrointestinal discomfort. More details about BPC-157.

Selank: stopping stress eating

Selank is a 7-amino acid neuropeptide with anxiolytic (anti-anxiety) action without sedative effect [20]. It's included in this review due to an indirect but important mechanism of weight impact.

How does it work? Chronic stress → elevated cortisol → accumulation of visceral fat + craving for sugar and fast carbs. This is the classic "stress eating" mechanism. Selank reduces anxiety, leading to decreased cortisol and, consequently, reduced craving for "comfort" food.

Selank is also in the FDA Category 2 list [29], so availability through official channels in the US is limited.

Form of use: intranasally, 2-3 drops × 2-3 times per day.

For whom: "emotional eaters", people with anxiety who notice a connection between stress and overeating. More details about Selank.

Cagrilintide: amylin analog from Novo Nordisk

Cagrilintide is a long-acting amylin hormone analog currently in phase 3 clinical trials as part of CagriSema (cagrilintide + semaglutide combination) [5].

Why is this interesting? Amylin is a hormone produced by the pancreas along with insulin. It controls satiety through a separate mechanism from GLP-1 — amylin receptors [5]. This means cagrilintide can be combined with Mounjaro or Ozempic to enhance effect.

Availability: DOZA offers Amilin from PeptoLabs — 10/20 mg pens. Dosage: start 1 mg/week, maximum 6 mg/week. More details about Cagrilintide (Amilin).

For whom: those who want to enhance Mounjaro's effect or overcome a plateau without increasing the GLP-1 dose. Also read: 7 strategies to break through a Mounjaro plateau.

NAD+/NMN: energy for weight loss

NAD+ (nicotinamide adenine dinucleotide) and NMN (nicotinamide mononucleotide, its precursor) are not fat burners in the direct sense. But without sufficient NAD+ levels, normal mitochondrial function is impossible, and therefore effective fat burning.

Why is this important on caloric deficit? When you eat less (which GLP-1 drugs ensure), the body needs energy for basic functions. If NAD+ is low — you feel fatigue, weakness, "brain fog". Many people on Mounjaro complain about exactly this.

NAD+ levels decrease with age, so especially relevant for people 40+.

NMN dosage: 500-1000 mg per day orally.

More details about NAD+ and NMN in the peptide catalog.

Safety and warnings: honest conversation

Peptides are not magic. And it's important to understand the real state of evidence base.

What we know for sure:

• Tesamorelin has FDA approval and RCT data on 816 patients [37]
• AOD-9604/HGH Fragment passed 6 clinical studies with ~900 participants and showed good safety profile [4]
• BPC-157 shows no toxicity in animal models even at high doses [31]

What we don't know:

• Long-term safety of most peptides in humans has not been studied
• 5-Amino-1MQ has no human clinical trials [34]
• MOTS-c is undergoing clinical trials, but results are not yet published [16]

What FDA says:

In 2023, FDA placed 19 peptides on Category 2 list, including MOTS-c, CJC-1295, Ipamorelin, AOD-9604, BPC-157, Selank and others [29]. This means the agency considers them as "may pose significant safety risks" due to potential immunogenicity, impurities and lack of large-scale human studies [26].

FAQ: answers to most frequent questions

Can peptides be combined with Mounjaro?

Yes, most peptides from this review work through different mechanisms than GLP-1. MOTS-c activates AMPK, 5-Amino-1MQ blocks NNMT, Ipamorelin stimulates growth hormone. These are different pathways that can be combined. The only limitation — don't combine multiple GLP-1 drugs together (for example, Mounjaro + Ozempic).

What's more effective for weight loss — GLP-1 or peptides?

GLP-1 drugs have incomparably stronger evidence base. Mounjaro showed -22.5% weight in SURMOUNT-1 study. No peptide from this review has such human data. But peptides can complement GLP-1 therapy, especially for muscle preservation and breaking through plateaus.

How long does a peptide course last?

Depends on the peptide and goal. Typical research protocols: HGH Fragment — 4-12 weeks, Tesamorelin — 26-52 weeks in clinical studies, MOTS-c — data still forming. Individual plan is selected by specialist.

Do peptides have side effects?

Each peptide has its own profile. BPC-157 has low risk of side effects in animal studies. Ipamorelin and CJC-1295 have concerns about immunogenicity according to FDA data. Tesamorelin can cause injection site pain and swelling. Detailed profile of each peptide is on catalog pages.

Conclusion: peptides are a tool, not magic

10 weight loss peptides don't compete with GLP-1 drugs — they complement them. Mounjaro and Ozempic block appetite. Peptides correct metabolism at cellular level. MOTS-c activates mitochondria. 5-Amino-1MQ blocks NNMT enzyme. Tesamorelin burns visceral fat. Ipamorelin + CJC-1295 stimulate growth hormone for muscle preservation.

Optimal strategy for many — GLP-1 for quick start + peptides for sustainable result and correction of specific problems.

But remember: evidence base of most peptides is still forming. Tesamorelin is the only one with FDA approval (though for specific indication). The rest are promising tools with preclinical data and limited human studies.
