amounts tested in animals and cells
No Human Thymulin Dosage Has Been Set
Every amount below came from a mouse, chicken, rat, or cell test. None is a direction for taking thymulin.
Animal doses don't supply a human thymulin dose
Animal tests used tiny amounts of thymulin in several ways. Researchers haven't settled an amount for people. The FDA hasn't approved thymulin as medicine. The amounts below aren't directions for you.
Some tests used billionths of a gram, while others used millionths. Each amount belongs to one animal and one way of giving it. You can't turn those amounts into a safe human dose. Published human work doesn't give a standard dose.
Animal tests used tiny thymulin amounts in different ways
One mouse test used 50 micrograms in the belly before researchers harmed pancreas cells [13]; another group got 10-50 micrograms under the skin before researchers gave the mice a virus [14]. Chickens got 10 nanograms or 50 nanograms per 100 grams of body weight [15]. Those chicken amounts are billionths of a gram.
A different mouse group received a daily amount for two weeks before researchers caused strong swelling [6]. The short report gave the timing but no amount. Brain tests in rats and mice used amounts from billionths to a few millionths of a gram [4]. Some went through a fine needle into the fluid-filled space around the brain.
The gene tests gave no measured amount of thymulin. One altered virus and one tiny particle carried instructions that made animal cells produce thymulin [5][7]. This differs from giving thymulin in a shot. No animal test supplies an amount for you.
Animal researchers gave thymulin by shots and tubes
Researchers put thymulin into an animal's belly [13], under its skin [14], or into fluid near its brain [4]. Other tests sent thymulin-making instructions down the windpipe [7], into muscle, or into the brain [5]. Lab workers also added thymulin to blood cells from badly fed children [8]. Each method answered a different research question.
Very little work involved people. Old trials used either thymulin with zinc or a man-made version. One small hair study used a scalp spray. No thymulin shot is approved for people.
The thymulin half-life in people is still unknown
Human tests haven't timed the thymulin half-life
Half-life is the time it takes for half a substance to leave the blood. Natural thymulin seems to leave quickly. Published papers don't give a sound half-life for people. That missing number also makes human dose claims harder to judge.
Animal researchers tried making cells produce thymulin over time. They chose that method because one amount of natural thymulin faded too soon [5]. This choice suggests thymulin leaves the blood fast. Animal work still gives no human half-life.
Zinc can change the result of a thymulin dose
Every dose test has the same catch: thymulin needs zinc. Taking zinc away stopped thymulin from helping young immune cells act mature [1][2]. Adding zinc restored that effect. The zinc level in an animal or blood sample can change the result.
That makes dose tests hard to compare. More thymulin may not do the same thing when zinc is low. Researchers often checked zinc for this reason. Even so, the tests couldn't separate every zinc effect from every thymulin effect.
No thymulin peptide dosage is backed for people
Animal amounts can't set a human thymulin peptide dosage
Researchers haven't set a tested thymulin peptide dosage for people. Each published amount belongs to one kind of animal and one way of giving it. Those amounts aren't plans for people. No sound human trial has filled this gap.
A seller may still print a human schedule. Published tests don't back such a schedule. Thymulin remains a lab substance, not an approved medicine. An exact human amount is a claim, not a settled dose.
