@Namddf My understanding of what @Mayfliersaid is that the psychological effects of this never-ending packaging changes can add up to to the fact (real, not imagined or nocebo effect) that women are having menopause symptoms on the dose that used to work for them.
Although this can be explained by perimenopausal hormone fluctuations in some cases, it doesn't seem to be a coincidence or an effect of mass hysteria that many postmenopausal women feel like the consistency of the gel is fluctuating as much as their own hormones used to.
And by 'consistency' I think both meanings apply here: consistency of the gel itself (different manufacturers, different raw materials suppliers, different pump suppliers) and consistency of packaging (which can lead to psychological effects).
These psychological effects can often be unconscious, so not all people are prepared to accept them, but they're REAL, not 'imagined'.
If our brains can 'create' menopause symptoms, I think researchers are missing the vital clue that we can control them as well. If only...
I have been puzzled by Besins products for a while now. I have started investigating them back in 2016 when I was in late stage perimenopause and tried Oestrogel for 3 months.
I had friends using Besins gel in other countries (which were supposed to be exactly the same, only different packaging and sometimes different brand names), but over the next couple of years all my friends living in the UK started complaining about their symptoms returning, while friends living overseas were fine.
Many of the UK users didn't even notice the Oestrogel label stuck to the Oestrodose bottle until they read about it on menopause forums, so I continued investigating even after things seemed to have resolved themselves. (As I have already emphasized a few times in this topic, it takes time for the body to reach a steady-state level of estradiol in the blood and tissues when absorption of the product is different from before).
I think the orange-green squares on the label might illustrate what I'm trying to say:
When my UK friends started complaining about their symptoms returning in 2020-21, they didn't notice the coloured squares. I asked them if they knew what the squares were supposed to mean and they all said 'Which squares?!'
I have been looking into this for almost a year and concluded that they meant different manufacturing locations, but I could be wrong and Besins said they were just printer codes.
Looking back, maybe they are just printer codes. I have been looking for printer codes on other product labels and have found them. They usually have the same colours as the bottles and cartons, but I recently found one that has a blue square and that colour is not on the carton (Italian Barilla Integrale Penne Rigate, lol).
I was intrigued because dark green had never been used on Oestrogel bottles, but then I realised that the Besins logo on Oestrodose bottles is/was dark green (and coincidentally looks like a square).
So yes, it could just be printer codes, but coincidentally (or not), patient information leaflets in the UK (and other countries) changed a few months after the squares appeared on the bottles.
They changed the manufacturer from Delpharm, Drogenbos Belgium to Besins Manufacturing Belgium, Drogenbos Belgium OR Laboratoires Besins International, Montrouge France.
It is therefore obvious that the changes to the packaging existed before the changes to the leaflet (probably because it takes time for changes to the leaflet to be authorised by the MHRA, although I think it's unacceptable to have a product with an old PIL).
Sorry for the long post, but it makes me sad when we can't look at these issues from a neutral perspective because we all struggle with a lot of things at this time in our lives and we certainly don't need to stress about pharmaceutical or medical technical stuff but, if necessary, we need to keep investigating.
As invaluable as personal experiences and opinions are, they are as different and virtually infinite as the number of individuals on the planet, and when it comes to menopause, they can change radically, not only between individuals, but within a single soul.
I hope this topic can be useful for all women who need help. It certainly helped me, after I had to leave a menopause forum for discussing the findings of my investigation, rather than just accepting what a 'knowledgeable' user had implied that it was 'all in our heads'.
