Adipotide vs Semaglutide
A targeted fat-destroying peptide that works like a smart missile, cutting off blood supply to fat cells and causing rapid weight loss in primate studies.
The revolutionary once-weekly GLP-1 medication that helps your body feel full faster and longer, leading to significant weight loss while also protecting your heart—FDA approved and backed by some of the largest clinical trials in obesity medicine history.

0.10 mg/kg
Once daily · About 2 weeks before stepping up
Adipotide is research-only and has never been approved for people. These numbers come from a dose-finding study in obese monkeys, where the dose was raised step by step every 2 weeks [2]. The first-in-man Phase 1 study started lower, at 0.03 mg/kg under the skin once daily for 28 days; it enrolled 4 people and was terminated without posting results [5].
0.25 mg/kg
Once daily · About 2 weeks at this step
Middle step in the rhesus macaque dose-finding study — not an approved or established human dose. Renal tubular degeneration with elevated creatinine was dose-dependent in those macaques, and this level sits at the point where that injury was observed. The mechanism makes it expected rather than incidental: adipotide is a homing sequence fused to a pro-apoptotic domain, and the kidney accumulates it. [2]
0.43 mg/kg
Once daily · Up to ~3-4 weeks at this level (studies ran 28 days at the top dose)
This was the best-working ("optimal") dose in obese monkeys, leading to about 10.6% body-weight loss over 28 days. It is from animal research and is not an approved or established human dose. [2]
Semaglutide
Subcutaneous
4 weeks
0.25 mg
Once weekly · 4 weeks
This is the starter dose to help your body adjust. It does not lower blood sugar much on its own, so it is only used for the first 4 weeks before stepping up [5].
At least 4 weeks at each step
0.5-1 mg
Once weekly · At least 4 weeks at each step
After the starter month, the dose goes up to 0.5 mg, and can rise to 1 mg if more blood sugar control is needed. Wait at least 4 weeks before each increase [5].
Ongoing/maintenance
2-2.4 mg
Once weekly · Ongoing/maintenance
The highest weekly doses. 2 mg is the maximum for diabetes (Ozempic) [5]; up to 2.4 mg is used for weight management (Wegovy) after a slower titration.
Oral
30 days
3 mg
Once daily · 30 days
The pill form (Rybelsus) starts at 3 mg each morning for 30 days. Like the starter shot, this dose is for getting started and does not control blood sugar by itself. Take on an empty stomach with a small sip of water, 30 minutes before food or other pills [6].
30+ days
7 mg
Once daily · 30+ days
After the first 30 days, the dose increases to 7 mg once daily. This is the first dose that actively lowers blood sugar [6].
Ongoing/maintenance
14 mg
Once daily · Ongoing/maintenance
The highest pill dose, used if more blood sugar control is needed after at least 30 days at 7 mg [6].
Best suited for
Adipotide
Targeted White Fat Reduction
Adipotide specifically seeks out and destroys the blood vessels feeding white adipose tissue. Unlike diet or exercise that shrink fat cells, this peptide actually eliminates fat tissue by cutting off its blood supply - a completely unique mechanism.
Stubborn Fat Deposits
Because it targets the vasculature of fat tissue directly, Adipotide may be particularly effective for stubborn fat deposits that resist traditional methods. The peptide homes in on prohibitin receptors found specifically on blood vessels supplying fat tissue.
Improving Insulin Resistance
Primate studies showed remarkable improvements in insulin sensitivity - treated monkeys used about 50% less insulin after treatment. This makes it interesting for research into obesity-related metabolic dysfunction.
Research Applications
As a pioneering vascular-targeting peptide, Adipotide represents a new class of potential therapeutics. Its unique mechanism of targeting specific tissue vasculature has implications beyond obesity research.
Semaglutide
People with Obesity Seeking Significant Weight Loss
If your BMI is 30 or higher (or 27+ with weight-related health conditions), semaglutide is currently one of the most effective non-surgical weight loss options available. [7] Clinical trials show average weight loss of 15% of body weight—that's 30+ pounds for someone starting at 200 pounds [1].
Those Who've Struggled with Diet and Exercise Alone
Semaglutide works by changing the biological signals that drive hunger and cravings. If you've tried to lose weight through willpower alone and found yourself constantly battling hunger, this medication addresses that underlying biology rather than just telling you to eat less [3][7][13].
People with Type 2 Diabetes Needing Better Control
Originally developed for diabetes, semaglutide excellently controls blood sugar while also promoting weight loss—addressing two major health concerns simultaneously. [3][5] It can often allow people to reduce or eliminate other diabetes medications [21].
Individuals at High Cardiovascular Risk
The SELECT trial proved that semaglutide reduces heart attacks, strokes, and cardiovascular death by 20% in people with obesity and existing heart disease—even without diabetes. It's one of the few weight loss medications proven to improve hard cardiovascular outcomes [2].

Safety overview
Everything known about adipotide's safety comes from animals. It has been given to mice [1], to mice and rats [4], and to obese monkeys of three different species [2]. The main safety finding is the kidneys. In the monkey study, the doses that worked best also produced changes in the function of the renal proximal tubule — the part of the kidney that reabsorbs what the body needs from filtered blood. Those changes were dose-dependent and they reversed after treatment stopped [2]. The selectivity claim comes from a direct comparison rather than an impression: the same peptide that completely reversed diet-induced obesity in mice on a high-fat diet did not reduce body weight in animals on a low-fat diet [4]. There is no human safety data. One first-in-man Phase 1 study opened in 2012 in men with metastatic prostate cancer and obesity. Four people were enrolled. It was terminated, the registry records the reason as the principal investigator's request rather than a safety finding, and no results have ever been posted [5].

Safety overview
Semaglutide has been studied in over 20,000 participants across multiple large clinical trials, making it one of the most thoroughly researched weight loss medications available. [1][2][8][9][10] The FDA approved it after rigorous review of safety data. While GI side effects are common (especially early on), serious side effects are rare. [1][7] The SELECT trial showed it actually reduces cardiovascular events, adding a safety benefit beyond just weight loss [2].
Contraindications
- Personal or family history of medullary thyroid carcinoma (MTC) [7]
- Multiple Endocrine Neoplasia syndrome type 2 (MEN2) [7]
- History of serious allergic reaction to semaglutide [7]
