Growth hormone releasing peptides
Your pituitary gland releases growth hormone in pulses, mostly at night, and that output declines with age. Growth hormone releasing peptides — sermorelin, ipamorelin, CJC-1295, tesamorelin — are studied for nudging the body's own pulses rather than replacing the hormone outright.
The articles below cover how each one works, how they differ from one another and from HGH itself, and what the research does and doesn't show. All of them are prescription-only through Promise: a licensed provider reviews every request.

Sermorelin Clinical Trials: What the Studies Show
The 11-man study is real. Its results are narrower than the sales pitch, and later studies add evidence without settling the big claims.
-
MOTS-c vs Tesamorelin: Not a Fat-Loss Contest
MOTS-c and tesamorelin work through different systems, and their evidence is not comparable. Tesamorelin has large late-stage trials for one narrow HIV-related condition; MOTS-c does not yet have completed human treatment results.
-
CJC-1295 Ipamorelin Oral: No Human Absorption Data
No human study has shown that a swallowed or sublingual CJC-1295/ipamorelin product delivers either peptide reliably. The key human drug-level studies used injections or infusions, not pills or troches.
-
Where to Inject CJC-1295 Ipamorelin: Site Guide
CJC-1295/ipamorelin is generally given into fatty tissue just under the skin. Common areas include the abdomen, thigh, back of the upper arm, and upper buttock, but the pharmacy label sets the sites for the exact prescription.
-
Sermorelin and Alcohol: Can You Drink?
No human study has tested sermorelin and alcohol together. The concern is less a known toxic interaction than alcohol working against nighttime growth-hormone release, sleep, and IGF-1.
-
Tesamorelin vs Tirzepatide: Which Fits Which Goal?
Tesamorelin and tirzepatide can both change fat-related measures, but they answer different clinical questions. One has narrow evidence for deep abdominal fat in adults with HIV lipodystrophy; the other was studied for total body weight.
-
Is CJC-1295 Ipamorelin Safe? What We Know
Short human studies offer limited reassurance, but the blend itself has not been tested in a published trial and its long-term safety is unknown. A careful answer has to include both facts.
-
MK-677 vs Sermorelin: Why the Route Matters
MK-677 is an unapproved oral ghrelin mimic, while sermorelin is a prescribed GHRH peptide. Both can raise growth-hormone signals, but only one comes with a provider, pharmacy record and follow-up.
-
Sermorelin Half-Life: About 11 to 12 Minutes
Sermorelin leaves the bloodstream in minutes, but the growth-hormone pulse it starts can last for hours. Those are two different clocks, and neither is a personal dosing or drug-testing deadline.
-
Does Tesamorelin Build Muscle? What Trials Show
Tesamorelin raised lean mass modestly in trials of adults with HIV-related lipodystrophy, but that is not proof of bigger or stronger muscles. It has not been shown to build muscle in healthy lifters.
-
Tesamorelin Before and After: The Study Timeline
Expect an early lab signal, not a one-month change in the mirror. The strongest trials measured deep abdominal fat at 26 and 52 weeks, all in adults with HIV-associated lipodystrophy.
-
When to Take Sermorelin: Why Bedtime Is Common
Bedtime is the usual convention because the body's largest growth-hormone pulse often follows deep sleep. It is a rhythm to work with, not proof that one clock time fits everyone.
-
Is Tesamorelin a Steroid? No—It's a GHRH Peptide
Tesamorelin is a peptide signal, not an anabolic steroid or growth hormone itself. It prompts the pituitary to release growth hormone, but sport rules still prohibit it.
-
Sermorelin Before and After: A Research Timeline
The research shows hormone changes within weeks, not a predictable visible transformation. Here is what small adult studies measured at two, six, and 16 weeks.
-
Tesamorelin 10 mg: What the Vial Number Means
A tesamorelin 10 mg label describes the total peptide in the vial, not the amount in one injection. The prescribed amount, liquid volume, and days of supply come from the pharmacy label and provider's plan.
-
CJC-1295 Ipamorelin Cost: What the Price Covers
There is no brand-name version of this blend, so there is no list price to compare against. What you are really choosing between is a prescription with a clinician attached and a vial with nobody attached.
-
Sermorelin for Muscle Growth: Evidence Is Limited
Sermorelin can raise growth-hormone pulses, but that does not automatically build muscle. The human studies are small, and they have not shown a reliable strength benefit.
-
Tesamorelin Cost: Brand vs. Compounded Prices
Public brand benchmarks run from about $6,000 a month at wholesale list price to roughly $10,709 for a 28-day cash quote. Insurance may bring that down for HIV-associated lipodystrophy; compounded tesamorelin follows a separate cash-pay path.
-
How to Get Sermorelin Prescribed: Four Steps
Getting a sermorelin prescription starts with a compound-specific medical intake, followed by a real clinician's review. Symptoms and labs can inform the decision, but neither guarantees a prescription.
-
Is Sermorelin a Steroid? No, It Is a Peptide
Sermorelin is a peptide signal that asks the pituitary to release growth hormone. It is neither an anabolic steroid nor HGH itself, though sports drug-testing rules still matter.
