AMOUNTS USED IN ANIMAL AND HUMAN SAFETY WORK
A vial number isn't a safe TB-500 dosage
You can check the amount, the animal or person, and how thymosin beta-4 or TB-500 entered the body. None gives you a tested human plan.
What the study amounts did in animals and cells
A TB-500 dosage table may look like directions, but each figure belongs to one old test. The animal, protein form, and way it entered the body all differed.
Heart and brain tests in rats and mice used about 6–12 milligrams of full thymosin beta-4 per kilogram of animal weight. A rat stroke test used 2–18 milligrams per kilogram through the belly; about 3.75 milligrams per kilogram looked best in those rats [4].
Weak mice received 150 micrograms of full thymosin beta-4 two times each week for six months [5]; a million micrograms together weigh one gram. More fibers looked rebuilt, but the mice stayed weak.
One dish test put 10 trillionths of a gram near skin cells beside a scratch. The cells crawled across that empty line [3], but the test didn't show healing in a person; still smaller amounts stirred hair-root cells [5].
Each amount belongs only to its own test. None can choose an amount for you, and none is advice.
What human amounts tell you about full thymosin beta-4
Only full thymosin beta-4 has human amount facts; the seven-part piece has none. Phase 1, the first step that checks safety, gave 42, 140, 420, or 1260 milligrams through a vein [6].
One amount came first, followed by daily use for 14 days. No problem made the researchers stop raising the amount.
That 14-day test speaks only to brief vein use of full thymosin beta-4. The brief test cannot choose your amount.
No matching human study has tested the TB-500 piece. An online "loading then maintenance" plan starts high and then drops, but no controlled human work supports that plan [5].
Rat stroke work also warns you that more may not help. At 18 milligrams per kilogram, the rats did worse than at 12 milligrams per kilogram [4].
What the half-life work can't answer
A half-life tells you when half of a substance has left your body. No sound human test gives a TB-500 half-life for the small piece.
In a Phase 1 vein test, higher amounts of full thymosin beta-4 took longer to leave the blood [6]. The report gives no one fixed time for you and doesn't call that longer stay helpful or harmful.
Drug tests find TB-500 and its broken-down remains in a horse's blood or urine [13]. Those tests catch banned use, but they don't show how your body clears the small piece.
Any exact hour claimed for TB-500 goes beyond the published work. The only amount-linked finding came from full protein given by vein, not TB-500 in you.
What can the TB-500 half-life tell you?
No sound human test gives a TB-500 half-life for the small piece [13]. Half-life means the time needed for half to leave; in a Phase 1 vein test, thymosin beta-4 remained in the blood longer after larger amounts, but the report gave no fixed hour or health benefit [6].
Why a loading plan can't become your dose
A list of old experiments is not a plan for your body. The animal, protein form, way it entered the body, and change being watched all differed.
An amount put into a rat's belly after a stroke can't turn straight into a human TB-500 plan. No human test has searched for a working TB-500 dose [6].
The rat stroke test makes the risk easy to see. The 2 and 12 milligrams per kilogram amounts helped movement, while 18 milligrams per kilogram did not [4].
More wasn't better for those rats. Online "loading then maintenance" plans start high and later use less, yet no published human trial has checked them [5].
Calling that schedule a tested dose would turn talk into proof. The known figures come from animals, different ways of giving the protein, and mostly the whole protein.
Community lore vs a clinical protocol
If the schedule is not evidence, whose schedule is it
The objection to loading protocols is not that the numbers are large — it is that no one accountable chose them. A community schedule is assembled by the person following it, from studies in other species. Prescription care begins with a licensed U.S. clinician checking the person's history, and that clinician can turn down the request. For TB-500, Promise Peptides is prescribing at mypromise.com; the clinician's judgment, rather than an online schedule, controls the prescription. People outside the United States cannot use this service, and a state's rules and the particular treatment can restrict the options. The compounded medicine does not have FDA approval. This digest still lists no human dose, because none has been established — the distinction here is about authorship of the protocol, not about a figure we are withholding.
How each study put the protein into the body
Most rat and mouse tests put full thymosin beta-4 into the belly. Researchers used a vein in the Phase 1 human test and in some heart tests.
For eyes and skin, researchers put the full protein on the sore area, including eye drops called RGN-259 [16]. In lung work, animals breathed the full protein in [15].
Some people also report shots just below the skin or deep in a muscle. No controlled human healing trial has checked either way [5].
TB-500 research powder is dried by freezing, then mixed with sterile water that may slow germ growth [16]. It stays cold because heat, repeated thawing, and other proteins can break it down.
A vial sold without drug-quality checks may contain another protein section or unwanted matter [17]. Careful measuring can't reveal your true amount when you can't trust what's inside [11].
