AMOUNTS GIVEN IN STUDIES
What Sermorelin studies gave each kind of patient
These aren’t personal directions. Studies used 14 or 30 millionths of a gram per kilo; blood removed Sermorelin within minutes.
What Sermorelin amount each group received
IGF-1 isn’t a blood test. It’s a hormone made mostly by the liver after growth hormone arrives.
There wasn’t one study amount. The people and the reason for care changed what researchers gave.
Here’s what each group received:
- Children low in growth hormone, 1996: They got 30 millionths of a gram per kilo in a bedtime skin shot. Among 110 children, their rate of growth nearly doubled by 6 months, and the paper called 74% good responders in year one [2].
- Short children with no known cause, 1994: The 18 children got 20 millionths of a gram per kilo twice daily for 12 months. Their rate of growth rose [3].
- Children harmed by past radiation, 1997: The 9 children got 15 millionths of a gram per kilo twice daily for 12 months. Their rate of growth rose [16].
- Older adults, 2001: They got 14 millionths of a gram per kilo, about 1 milligram, beneath the skin at night. Over 5-6 months, IGF-1 rose 35%, fat-free weight rose 5%, and deep belly fat fell [4].
- Men with fat buildup linked to HIV, 2004: They got 1 milligram under the skin two times a day for 12 weeks. Their liver-made growth hormone in blood and fat-free weight rose more than with placebo, a shot with no drug [10].
- Men low in testosterone, 2017: They got 100 millionths of a gram of Sermorelin three times daily with GHRP-6 and GHRP-2, two lab-named drugs that also raise growth hormone. In 14 men, IGF-1 rose over a 134-day period [9].
These are study records, not choices made for you. Your health and medicines weren’t part of those plans.
You can compare yourself with each group. You can’t turn a research amount into a dose for yourself.
How often studies gave Sermorelin
You won’t find one set schedule in the studies. They gave shots under the skin once, twice, or three times a day.
Adult studies often chose bedtime to match the night growth-hormone burst [4][8]. The child study used 30 millionths of a gram per kilo of body weight at bedtime [2].
A 2004 trial used 1 milligram twice daily for men with fat buildup linked to HIV [10]. A 2017 drug-mix study used three shots daily [9].
The section on why studies used bedtime explains the study schedules.
How fast Sermorelin leaves the bloodstream
Sermorelin leaves quickly. After healthy men got it through a vein, half was gone from blood within minutes.
The 1994 work found that blood proteins broke the drug apart [7]. That lab math can’t tell you how long you’d feel anything [7].
Less than 4% of a skin shot reached blood [14]. The study didn’t say that the rest stayed under the skin or caused trouble there.
Growth hormone peaks at 30-60 minutes and fades within 3-4 hours. Your gland may keep responding after the drug has gone.
Researchers altered the drug and measured blood clearing about 21 milliliters per kilo each minute [7]. For you, that rate only means the altered drug left fast.
The altered drug wasn’t ordinary Sermorelin. Its rate can’t give an exact clearing time for your medicine.
What keeps changing after Sermorelin is gone
Very little Sermorelin stays in blood. A 1994 vein test found that half was gone within minutes [7].
A review put that time at about 8 minutes after a skin shot [14]. Your growth gland kept answering longer.
Growth hormone peaks at 30-60 minutes and falls within 3-4 hours. The hormone wave remains after much of the drug is gone.
IGF-1 isn’t a blood test. It’s a hormone made mostly by the liver after growth hormone arrives. The IGF-1 level can stay high for 12-15 hours, longer than Sermorelin.
Where studies put the Sermorelin shot
Trials put the shot into fat under the skin of the belly, thigh, or shoulder [4][10]. Child and adult studies both used that route.
Shots into muscle appeared less often. Tests used a vein only to see how fast blood removed the drug.
Those vein tests ran in 1994 and 1993 [7][8]. You wouldn’t get the usual treatment that way.
Nasal sprays put less drug into the blood. Pills haven’t worked in human trials because your stomach breaks peptides apart.
Why Sermorelin studies often chose bedtime
The largest growth-hormone burst often comes in deep sleep. Evening Sermorelin was meant to add to that night burst [8].
The old child study of Sermorelin used bedtime [2]. A 2001 study of older adults did too [4].
A 1993 study tested healthy young men during sleep. They got Sermorelin through a vein; the exact lab amount doesn’t guide your care.
Late in sleep, a machine showed much more deep sleep [8]. Early in sleep, dream sleep rose but deep sleep didn’t.
You’ll see that the test time changed the result. That doesn’t make bedtime right for you.
How soon Sermorelin studies found changes
IGF-1 isn’t a blood test. It’s a hormone made mostly by the liver after growth hormone arrives.
Growth hormone can rise within 30-60 minutes after a shot [7][8]. Changes in sleep, fat, or fat-free weight take longer.
Studies found those changes after 4-12 weeks of steady use. You can’t judge every result from the first night.
A 2001 study checked people after 5-6 months [4]. A 1996 child study found faster growth by 6 months [2].
A 2004 trial checked body fat at 12 weeks [10]. The liver-made growth hormone in blood can change before your body looks different.
What studies say about storing Sermorelin
The studies don’t give home storage rules. A pig-blood dish test broke down half the drug in about 13 minutes [7].
That dish result can’t tell you how to store a bottle. It also can’t show what your body would do.
Researchers made altered versions that lasted longer. In studies, mixed Sermorelin stayed cold and was often prepared shortly before the shot.
Less than 4% of a skin shot reached blood [14]. Slow entry and fast breakdown may both explain that small share.
