Why this capsule has been flying off the shelves since June 2026: the next step after GLP-1 that replaces the weight-loss pen - no needle, no prescription.
GLP3-B is the further development of GLP-1 - the daily capsule that replaces the classic weight-loss injection.
It started with a few Instagram Stories...
...then the whole internet kicked off. A capsule called "GLP3-B" is being hailed as the further development of GLP-1 - and it replaces the weekly weight-loss pen.
No injection. No prescription. And no four-figure monthly bill for private pens.
Within six weeks, the manufacturer's site has been crashing for hours at a time.
Thousands of people are posting their results every day: a stone and a half, two stone, three stone down - eating normally, with just one capsule a day.
What do doctors say? The capsule that replaces the weight-loss pen - the next step after GLP-1
Endocrinologist Dr Elias Shaw has been testing GLP3-B in his clinic since spring 2025 on more than 180 patients who either refuse the pen or cannot tolerate it.
Results from his practice so far:
- Average loss of 11.6 kg in 12 weeks (around 1 st 12 lb)
- 9 out of 10 users report that emotional eating and cravings have completely gone
- None of the typical pen side effects - the heavy nausea, vomiting or diarrhoea that push so many people off the injection and onto the capsule
- Works with PCOS, an underactive thyroid, and for people over 55
According to Dr Shaw, the effect comes down to the patented "MS-Phase Complex":
The formula targets the outer membrane of overloaded fat cells, so the body can break down and burn stored fat naturally - without slamming the metabolism into reverse the way weight-loss pens often do.
A second active ingredient blocks ghrelin signals in the brain - appetite settles down on its own.
(Ghrelin is the "hunger hormone" made in an empty stomach. It keeps telling your brain: "Eat. Now.")

The first change she could see came in week two.

"I'd fought with my weight for years. Honestly, I was ready to give up."

"Someone put me onto GLP3-B as the further development of GLP-1 - a capsule instead of the pen. I've got a proper phobia of needles, so an injection was never going to happen."
"I took GLP3-B for 3 months (once a day) and lost nearly 4 stone. No side effects at all."

Why GLP3-B replaces the weight-loss pen - and takes GLP-1 further
Because GLP3-B is the next step after GLP-1: appetite control and fat metabolism in a daily capsule instead of a weekly injection. No prescription. No needle. No pen routine.
Instead of jabbing yourself in the stomach once a week, you take 1 capsule a day. A month's supply currently runs about £45 to £50 - not the £1,000+ people are paying privately for pens.
Why this capsule is leaving everything else behind - according to the studies
Clinical studies covering 1,800 participants were published in summer 2025.
In a further study of more than 500 people, GLP3-B users lost an average of 7.5 kg more per month than the control group.

Danish research with 1,300 participants also showed an average reduction of 8.3 kg per month with regular use.

Saw in Grazia that some actress wouldn't go on the GLP-1 pens cos of needle phobia and tried GLP3-B instead. Apparently worked a treat for her.

Mate of mine gave me GLP3-B a few days ago - you notice straight away. No more grazing and I'm properly not hungry all day. ❤️

Nearly a stone off in a month - and I properly forgot to take it like 4 times 😂

Do you have to cut anything out while you're on it?

Did GLP3-B and dropped just under 3 stone. Hasn't crept back on either - actually brilliant!

Mate recommended it - dead chuffed. No side effects, dead easy to take.

15 days in - already nearly 9 lb down without the gym. Reckon it'll be even better once I get moving more.

Can blokes take this as well?

Yeah - my boyfriend's on it and it's worked a treat for him. I've just started too.

I can't swallow tablets and needles are an absolute no… but GLP3-B is easy and I'm already about 7 lb down.
