Something I hadn’t realised until very recently: the hormones used in hormone replacement therapy (HRT) were originally – and sometimes still are – made from horse wee.
Are Premarin foals slaughtered?
The vast majority of Premarin mares give birth to a foal every year. Afterward, they are almost immediately impregnated again. If they fail to become pregnant, they are sent to slaughter. If they do become pregnant again, their foals are taken from them at the premature age of just three to four months.
Does estrogen increase performance?
In these other musculoskeletal tissues, estrogen improves muscle mass and strength, and increases the collagen content of connective tissues. However, unlike bone and muscle where estrogen improves function, in tendons and ligaments estrogen decreases stiffness, and this directly affects performance and injury rates.
Is Premarin made from horses?

What animal has the highest estrogen?
Poultry manure has among the highest hormone content, quadruple the total estrogens, and nine times more 17-beta estradiol, the most potent estrogen and a “complete” carcinogen, as it exerts both tumor initiating and tumor promoting effects.
Is chicken full of estrogen?
The high estrogen levels in Japanese and USA chicken, especially that of E2, exceeded those of human fat (16.3, 157.1), while the levels in meat of low estrogen content were a hundred times lower than in human fat.
Do cows have estrogen?
Naturally occurring of steroid hormones in animals has been frequently reported. Oestrogens especially 17-β-oestradiol and estrone are found in different parts of beef and veal including muscle, liver and fat (81, 82). Tissues from adult cattle in comparison to the calves consist of low amounts of estrogens.
Do horses prefer female riders?
“Assuming that there is no difference in riding ability, from the horse’s point of view it does not seem to matter whether its human partner is male or female,” concluded the study’s co-author Christine Aurich.
Is Premarin still on the market?
There is currently no therapeutically equivalent version of Premarin available in the United States.
What is horse urine good for?
Premarin is a very common drug prescribed to millions of women worldwide as a hormone replacement therapy. The name stands for PREgant MAres uRINe, as the drug is produced from the hormones present in the mare’s urine. The horses used to produce this drug are referred to as “PMU” horses, for short.
Is Premarin cruel to horses?
Premarin mares are forcibly impregnated over and over again to continually produce high levels of estrogen for Premarin products; their pregnancies last for 11 months, then they are impregnated again after giving birth – a cruel, physically exhausting, non-stop cycle for mares.
What happens if a human touches Regumate?
Acute effects after single exposure are possible; however, continued daily exposure has a greater potential for these effects. Acute effects include disruption of the menstrual cycle, uterine or abdominal cramping, increased or decreased uterine bleeding and headaches.
