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.

    Tesamorelin Cycle: Why Doctors Talk About Duration

    There is no on-and-off tesamorelin cycle in the research. The trials ran it daily for 26 weeks and then 52 — and when people stopped, the visceral fat came back.

    CJC-1295 Ipamorelin for Muscle Growth: No Trial

    These peptides can raise signals along the growth hormone pathway, but no human trial has shown that the pair builds muscle or increases strength. The honest case is a plausible mechanism, not a bodybuilding result.

    Sermorelin Nasal Spray: What Gets Past Your Nose

    The one study that measured it found about 3 to 5 percent of a nasal dose reached the bloodstream. That number, and what happened when researchers kept spraying for six months, is most of the story.

    What Is Tesamorelin Used For?

    Tesamorelin has one narrow labeled use: reducing excess abdominal fat in adults with HIV-associated lipodystrophy. Uses beyond that label need a more careful answer.

    Sermorelin Cost: What You’re Really Paying For

    In three current public telehealth listings, recurring sermorelin plans run from $149 to $279 a month. The useful comparison is not just the vial price, but what the plan includes and who is accountable for it.

    Tesamorelin Half-Life Is Measured in Minutes

    Tesamorelin leaves the bloodstream quickly, but the signal it starts can last much longer. That difference explains why trials used it once daily and why providers follow IGF-1 instead of watching the clock.

    Is Sermorelin FDA Approved? Not Since 2009

    Geref, the only sermorelin product the United States ever approved, left the market in 2008 and its approvals were withdrawn in 2009 — not over safety. Here is what that means for a prescription today.

    What Is Sermorelin Used For? A Plain Answer

    Sermorelin was approved once, for children who were not growing. Adults are prescribed it today for sleep, body composition and recovery — uses that rest on a handful of small studies.

    CJC-1295 Ipamorelin for Women: Evidence and Limits

    CJC-1295 with ipamorelin may stimulate the growth-hormone axis, but no clinical trial has tested the combination specifically in women. Perimenopause, estrogen route and the limits of body-composition and sleep evidence all matter to the prescribing decision.

    Does CJC-1295 Ipamorelin Work? Evidence Review

    The combination has no clinical trial of its own. Separate studies show that CJC-1295 and ipamorelin can raise growth hormone signals, but they do not establish predictable sleep, recovery, muscle, or fat-loss results from the blend.

    Does Sermorelin Cause Hair Loss? Evidence Review

    Current evidence does not identify hair loss as a sermorelin side effect. Growth hormone and IGF-1 affect follicles, but that biology cannot explain why one person starts shedding.

    Tesamorelin for Women: Evidence and Menopause

    Tesamorelin for women has limited female-specific evidence: pivotal trials enrolled 84%–86% men, and no trial was designed for menopause-related abdominal change. Hormone therapy, pregnancy, glucose and IGF-1 all change the prescribing conversation.

    Tesamorelin Injections: Sites, Timing, and Storage

    Tesamorelin is injected under the skin once daily. The abdomen, site rotation, timing, device format, and storage instructions all matter—and they are not identical across branded and compounded formulations.

    FDA Peptide Warning Letters: What They Mean

    FDA’s five August 24 letters targeted the way online sellers presented injectable peptides for people—not peptide molecules as a class. Here’s what changed, what didn’t, and how a prescription route differs.

    Does Tesamorelin Work? What the Trials Show

    Tesamorelin reduced visceral abdominal fat in two large phase 3 trials, but those studies involved adults with HIV-associated lipodystrophy. The evidence does not establish it as a general weight-loss medication or promise the same result for every patient.

    Sermorelin for Men: Testosterone, Muscle & Sleep

    Sermorelin can stimulate growth-hormone release when the pituitary responds, but it is not testosterone therapy. Small studies in older men found biochemical changes and mixed body-composition or strength results, with no reliable sleep or recovery benefit established.

    Sermorelin Tablets: Do Oral Forms Work?

    Tablets, troches and rapid-dissolve forms sound simpler than an injection. The unresolved question is whether they deliver intact sermorelin into the bloodstream in a reliable amount.

    Sermorelin for Weight Loss: What Studies Show

    Sermorelin is not a weight-loss drug. It changes growth-hormone signaling, but small older-adult studies found hormone effects without reliable scale-weight loss.

    Tesamorelin vs CJC-1295: Evidence and Differences

    Both peptides signal through the GHRH receptor, but their structures, duration and human evidence differ sharply. The clearest distinction is phase 3 visceral-fat data for tesamorelin versus biomarker studies for CJC-1295.

    Is Tesamorelin FDA Approved? Not Every Form

    Egrifta has an indication-specific approval for adults with HIV and lipodystrophy. Tesamorelin offered here is dispensed as a compounded medication, which is different from an FDA-approved product: the formulation is not FDA-approved.
