Sermorelin FAQ: what have studies answered?
Use these twenty answers as notes for your doctor. Each one gives the finding and its limit.
Has Sermorelin helped a human brain in a study?
No human study here shows that Sermorelin helps the brain. One trial found changes in thinking scores with a related drug [6]. Other related drugs changed harmful brain proteins in mice [7]. Neither result proves that Sermorelin would help your thinking.
Did a Sermorelin-like drug help older adults think?
One 152-person trial followed older adults for 20 weeks. They received 1 mg of tesamorelin, a related drug, before bed each day. Some thinking scores improved, and IGF-1 rose 117% [6]. Researchers didn't test Sermorelin, so you can't expect the same result.
What is Sermorelin made to do?
Sermorelin belongs to the peptide drug group, which uses short rows of protein parts. Its 29-amino-acid chain mirrors part of one brain hormone. Your growth gland responds by putting growth hormone in your blood [12]. FDA once approved the drug for children, while pharmacies now mix it for individual prescriptions [15].
What happens after Sermorelin reaches the gland?
The drug fits a matching place on your growth gland's cells [11]. The cells react by adding growth hormone to your bloodstream. Your liver then makes insulin-like growth factor 1, called IGF-1. Messages from both hormones can slow further release in your gland.
Which Sermorelin uses have support from studies?
The clearest result comes from children with a growth-hormone shortage. With daily treatment, their growth speed rose from about 4.1 to 7-8 cm/year [1]. Older men got 0.5-1 mg twice each day for 14 days, and their 24-hour IGF-1 blood levels rose [2]. Studies still haven't shown a long-term anti-aging benefit for adults [5].
How soon did a Sermorelin study find a change?
Growth hormone rose within minutes after Sermorelin entered the blood. The higher level lasted about 3 hours [3]. Older men's 24-hour insulin-like growth factor 1, called IGF-1, and growth hormone changed after 14 days [2]. Blood-test timing can't tell you when you would feel a change.
Why did doctors once give Sermorelin to children?
Doctors once used Sermorelin to test or treat children with a growth-hormone shortage [1]. Later adult studies checked IGF-1 blood tests, thinking, sleep, and body fat. Those adult uses remain unproved as care. The findings can't tell you to take the drug.
Does Sermorelin improve sleep or disturb it?
Growth hormone usually rises most during deep sleep [11]. That usual hormone rise grows weaker with age. Researchers therefore gave many study shots at bedtime. One good or bad night can't take the place of a measured sleep study.
Why did some Sermorelin studies use bedtime shots?
Your largest growth-hormone burst comes during early deep sleep [11]. Researchers chose bedtime to meet that usual rise. They found that the hour changed the hormone response. That study choice isn't a dose schedule for you.
Has Sermorelin been proved to lower body fat?
Tesamorelin, not Sermorelin, produced the stronger fat finding. That related drug beat a placebo, a dummy treatment with no drug, for deep belly fat. Body fat fell 7.4% in a 20-week trial [6]. Your body uses growth hormone when drawing on fat stores [11], but that doesn't prove Sermorelin lowers your weight.
Has Sermorelin been shown to change testosterone?
Sermorelin works with growth hormones, but one study gave older men testosterone. Insulin-like growth factor 1, or IGF-1, and growth hormone then rose [2]. IGF-1 sent a slowing message, while deep belly fat had the strongest tie to a weaker growth-hormone response. The study doesn't show that Sermorelin changes your testosterone.
Has Sermorelin built muscle in a fair trial?
No fair trial shows that Sermorelin builds muscle in a healthy adult. Growth hormone and IGF-1 can rise after the drug [2]. Reviews ask whether insulin-like growth factor 1 might help muscle lost with age [12]. That question isn't proof, so muscle claims go beyond the facts.
How does Sermorelin differ from a growth-hormone shot?
A direct shot places finished growth hormone in your body, while Sermorelin asks your gland to use its stored supply [11]. IGF-1 can still tell your gland when to slow. One article said that process may fit your usual body rhythm better [4]. It didn't prove that your result would be better.
Which Sermorelin harms appeared in studies?
Trials found mild skin trouble, and some children made immune-system proteins without harm to their growth [1]. Longer tests of related drugs sometimes found worse blood-sugar control or a brief rise in blood fats. Growth hormone and IGF-1 help cells grow. Very high levels could also aid unwanted cell growth, but studies haven't shown that Sermorelin causes cancer [11].
When did Sermorelin studies give the shot?
Many studies gave Sermorelin at bedtime. Your biggest growth-hormone burst comes during deep sleep [11]. Researchers also found that the hour changed the hormone response. Those study times aren't directions for your care.
Do 3 months of Sermorelin make a proved course?
No single course has been proved for adults. Studies of growth hormone and IGF-1 ran from 14 days to 16 weeks [2]. The thinking trial ran 20 weeks [6], while child-growth trials ran 6 to 24 months [1]. Those spans answer study questions, not how long your care would last.
Sermorelin before and after: which study results changed?
Children's growth speed rose from about 4.1 to 7-8 cm/year [1]. In older men, 14 days of Sermorelin raised 24-hour growth hormone and IGF-1 [2]. A related drug raised IGF-1 by 117% and lowered body fat 7.4% [6]. Those measured changes don't predict what will happen to you.
How does Sermorelin prompt the growth gland?
The drug fits a matching part of your growth-gland cells, which respond by adding growth hormone to your blood [11]. Your liver then makes insulin-like growth factor 1, called IGF-1. Both hormones tell your gland when to slow. That brake keeps the flow in brief spurts instead of one steady stream.
