Never realised about the animal cruelty aspect of weightloss injections

Saw an article yesterday about monkeys getting force fed in order for WLI to be tested on them. The monkey looked really distressed. Feel absolutely sick. I’d just assumed there had been human trials, never thought about monkeys.

Does anyone know if it’s all WLI or have some never been tested on animals?

Oh good another thread, all drugs are tested on animals, how do people get to adult hood and not know this.

WhatAMarvelousTune · 22/04/2026 21:16

Virtually all new medications are tested on animals before humans.

@WeAllHaveWings really? Hide thread function? Please tell me how.

Op surely we don't need yet another I'll informed thread on this, with a link to a rubbish tabloid.

Do you not take any medicines OP? I presume not from yiur post but just checking

WeAllHaveWings · 22/04/2026 23:28

@MoneyJo on safari it’s here at the top of the thread and it disappears forever!

There is similar on the app

@WeAllHaveWings thanks so much. I've been here decades and never knew! I'll start with the animal testing threads.

Backawayfromthesausage · 23/04/2026 06:43

I was bizzarely thinking about this, and the ops question if any aren’t tested on animals, she thought they were tested on humans,

apart from the fact that would be utterly illegal to first step test medications on humans, human beings will never have their lives risked as she is suggesting.it is abhorrent to even suggest it,

It tells me some people see this as a purely cosmetic, and don’t grasp this is a medication to cure a disease.

How have you only just realised medications are tested on animals, OP?

I think it’s the force feeding and general distress I don’t like. If they just had a naturally chubby monkey that they gave mounjaro to that wouldn’t be so bad.

As mounjaro was originally licenced for diabetes. The testing on the animals would be to check how insulin levels reacted to the drug. They wasn't trying to make the money skinny.

I suppose because people learn different things at different times.
Also ‘testing’ isa broad term and not everyone knows the specifics

Op, it is a preclinical requirement for all medication. And no no one likes it. I am assuming you didn’t read the fail article. It was simply click bait heading, the article explains it is for all drugs, and there is no suggestion the images are from animals being tested on mounjaro, they are simply images an employee took of animal testing.

Backawayfromthesausage · 23/04/2026 07:41

Op, do you understand why medication is trialed on animals bred for this purpose first, it is to protect humans who enter trials, you cannot severely risk the life of human beings, in the manner you suggest and there is no other way. So yes, animal testing for all mediation is a preclinical legal requirement. You can’t be killing or giving cancer to people who enter trials. Yes it’s horrible animals are used in this way, and yes there is no other way. But to suggest we line up humans and have them risk their lives instead is not ok.

A lot of cosmetics too. I just thought it was common knowledge

Has everyone missed the bit about monkeys? It's extremely rare in the UK to experiment on monkeys - only around 2000 are used every year out of around 2 1/2 million animals. The ethical implications are huge and can't be dismissed or minimised.

We wouldn't have any medication otherwise

I don't take this stuff, by the way

This just caught my eye

chubby monkeys, sorry but that is funny

This is nonsense, it is not rare it is standard preclinical practice , it is howver a tiny percentage of the overall animal testing schedule for a drug, less than half a percent, so 95 percent is done on mice or rats, and then it moves to monkeys and other animals. It is a legal requirement as the dna is so closely matched to us. Thays why the number is low. It’s a small percentage of the over all trial, the animals are bred for this purpose.

th number is low as it is a small percentage of any given animal trial uses monkeys .

In addition few drugs are British and undergo pre clinical trials in the uk. For example approx 30k monkeys are used a year in the USA for drug trials. Mounjaro and wegovy did their preclinical trials mainly in the USA. In the uk it was done for these drugs purely for pregnancy side effects.

mainky in the uk it has been arthritis medication, aids medication and for addiction ie cocaine etc.thats under went trials on monkeys.

Another good reason to steer clear of WLI.
I thought we'd got past the days of animal testing. Clearly not. Still can't believe people think this is fine.

People don't think it's "fine". It's a legal requirement in the UK to do animal toxicity tests on any new medication. It's not about WLI specifically, so I hope you are as annoyed at people who use any other medication.

The UK MHRA, the UK government and the pharmaceuticals industry are committed to reducing and eventually hopefully removing animal testing, via new technologies. What aspects of that do you disagree with or have an issue with?

MasculineProviderEnergy · 23/04/2026 09:47

Unfortunately all medicines are tested on animals. I wish humans would accept that death and illness are part of life, and stop torturing animals. Or test on the murderers that we have in our prisons.

We’re not scientifically able to replace animal testing completely yet. This is the unfortunate reality. Drug safety testing still legally requires animal data before human trials.

To avoid WLIs because of animal testing makes no sense. By that logic, you’d have to avoid most pharmaceuticals altogether, not just weight-loss ones.
