The Synedica Semaglutide® Injection Pen Kit is a clinically advanced treatment for weight loss. Known commonly as Ozempic, semaglutide works by mimicking the natural hormone GLP-1, which signals to your brain that you are full after eating. By reducing appetite and cravings, it supports significant and sustainable weight loss.

2 × Synedica semaglutide pens (each containing 4mg)
12 × disposable 32g 4mm needles
1 × instruction booklet
Each pen delivers up to 4 full doses of 1mg or smaller increments of 0.25mg, 0.5mg, 0.75mg, or 1mg, depending on your prescribed dosage.
Recommended Dosage Schedule:
Weeks 1–4: 0.25mg once weekly
Weeks 5–8: 0.5mg once weekly
After 8 weeks: Your doctor may increase to 0.75mg or 1mg once weekly
Synedica Retatrutide® Injection Pen Kit is the world’s most advanced weight loss solution. Retatrutide is an advanced medication which suppresses appetite leading to significant weight loss. It does this by mimicking the effects of the GLP-1, GIP and glucagon receptors, which are natural hormones that makes humans feel full from eating much smaller portions of food.
The Synedica Retatrutide® 40mg Injection Pen Kit contains 1 pen, 12 disposable needles and an instruction booklet.
Each pen has 40mg which can be delivered across 4 full doses of 10mg, or in increments of 2.5mg, 5mg, 7.5mg or 10mg.
Recommended dosage is 2.5mg for the first 4 weeks, then 5mg for the next 4 weeks. After 8 weeks the weekly dosage may be increased to 7.5mg or 10mg if necessary.
Week 5-8 (second dose) Each pen lasts for 4 weeks. Your starting dose will be 0.25mg unless you have previously used Ozempic, Wegovy, Rybelsus or Saxenda. Your dose will be titrated up as you progress. If you are obese or overweight and need help with your weight management, Wegovy can help you.
Losing weight is a journey that works best with a holistic plan: balanced nutrition, activity, sleep, and supportive care. Medical treatments can add a clinically proven boost. Below is a clear guide to options we provide or discuss: Mounjaro, Wegovy, Mysimba, Saxenda, Orlistat, Alli — plus context on Ozempic.
| Treatment | Active ingredient | How it’s taken | Notes |
|---|---|---|---|
| Mounjaro | Tirzepatide | Once-weekly injection | Highest average weight loss in trials (~22.5%). Titrate from 2.5 mg; max maintenance 15 mg. |
| Wegovy | Semaglutide | Once-weekly injection | Clinically proven for sustained weight management; appetite regulation. |
| Mysimba | Naltrexone + Bupropion | Oral tablets | Works on brain pathways for appetite/cravings; best with low-calorie diet + exercise. |
| Saxenda | Liraglutide | Daily injection | Supports appetite control when lifestyle changes alone aren’t enough (~10% avg weight loss). |
| Orlistat | Orlistat | Oral capsules | Blocks some fat absorption; pair with reduced-calorie, lower-fat diet. |
| Alli | Orlistat (60 mg) | OTC oral capsules | Lower-dose, pharmacy version of Orlistat for overweight adults. |
Mounjaro is the latest weekly injection pen and has demonstrated the strongest average effect size in clinical studies (~22.5% body-weight loss). This compares to ~10% with Saxenda and ~15% with Wegovy/Ozempic.
A once-weekly injection from Novo Nordisk that helps regulate appetite and metabolism. It’s clinically proven to support sustainable weight management when paired with lifestyle changes.
Mysimba combines naltrexone and bupropion. It is most effective alongside a low-calorie diet and regular exercise, working on brain pathways linked to appetite, energy balance, and cravings.
An injectable prescription medicine for adults with obesity or weight-related conditions. It mimics a natural hormone to help regulate appetite and food intake—used when lifestyle measures alone aren’t enough.
Orlistat blocks a portion of dietary fat from being absorbed, so it passes undigested. Best used alongside a reduced-calorie, lower-fat diet, exercise, and behaviour change support.
Alli is the over-the-counter, lower-dose version of orlistat. It helps prevent fat absorption and supports a low-fat, reduced-calorie diet for overweight adults.
Ozempic is widely known but isn’t licensed for weight loss in the UK; it’s licensed for diabetes treatment. Some doctors prescribe it off-licence for weight management and it can be effective.
Active ingredient: Semaglutide (the same as Wegovy).
