Three prescription peptides — sermorelin, CJC-1295/Ipamorelin, and tesamorelin — work through growth-hormone signaling pathways tied to body composition, recovery, sleep quality, IGF-1 response, or visceral-fat reduction, depending on the molecule. Different strengths. Different jobs. One missing signal. Here is the honest side-by-side.

The scale was never the whole equation.
You knew that already.
Body composition during weight loss comes down to signaling. One signal helps drive weight loss. A different pathway may help support lean tissue, recovery, and body composition during the process. Here is the whole picture, the way it should have been explained the first time:
Reduces appetite, slows gastric emptying, supports weight loss. It helps reduce appetite and drive the plan forward. But it was not designed as a lean-mass support protocol.
A GLP-1 protocol alone does not directly address lean-mass support. During rapid weight loss, lean mass can leave along with the fat. The plan is silent on this.
Sermorelin, CJC-1295/Ipamorelin, and tesamorelin all work upstream: they signal your pituitary to release more of your own growth hormone, in pulses, with the feedback loop intact. Same destination — three different routes, strengths, and specialties.
All three are growth-hormone secretagogues: they do not supply growth hormone, they work upstream through growth-hormone signaling. Where they differ is how hard they push, how long the signal lasts, and which job each one is best documented for. That difference is the whole decision — and it is exactly what the comparison below is for. Weight loss plus lean-mass support. That is the more complete conversation.
No favorites, no mystery blends. Here is what each one is, what it is best documented for, and what it costs — straight from the same catalog our providers prescribe from.
A GHRH analog that tells your pituitary to release more of your own growth hormone — at night, in the same pulsatile pattern your body already uses. It was previously FDA-approved for certain diagnostic and pediatric uses; today it is prescribed as a compounded medication.
A GHRH analog paired with a ghrelin mimetic — two receptors, one stronger signal. In a Phase 1 trial in healthy adults, a single dose of CJC-1295 raised mean IGF-1 levels 1.5–3x above baseline for 6+ days (Teichman et al., JCEM 2006).
A synthetic GHRH analog and the most studied of the three for one specific job: visceral abdominal fat. Tesamorelin is FDA-approved for reducing excess abdominal fat in HIV-associated lipodystrophy; prescribing it for body-composition optimization is off-label.
| Sermorelin | CJC-1295 / Ipa | Tesamorelin | |
|---|---|---|---|
| What it is | GHRH analog | GHRH analog + ghrelin mimetic | Synthetic GHRH analog |
| The signal | Gentle, pulsatile, nightly | Stronger, longer (IGF-1 1.5–3x for 6+ days in Phase 1) | Targeted, visceral-fat focused |
| Human data | Long clinical history; previously FDA-approved for diagnostic/pediatric uses | Phase 1–2 human data; research continues | FDA-approved for HIV-associated lipodystrophy; body-composition use is off-label |
| Best fit | Sleep, recovery, lean-mass baseline | Harder training, bigger signal | Waistline and body composition |
| Starting at | $149/mo | $199/mo | $188/mo |

You do not have to pick one from a table.
That is what the provider review is for.
You already know the weight-loss numbers. Here are the ones that explain what the weight was made of:
Ranges from published weight-loss composition research; figures vary by study, medication, and individual. These are compounded prescription medications. Individual results vary.
If you've gone looking for secretagogues online, you've seen the grey market: "for research purposes only," overseas shipping, payment apps with stranger's names. Here's the physician-guided route:

A real clinician reviews your health history, current medications, and contraindications — and matches the molecule to the case. If none of the three is appropriate for you, they'll tell you honestly.

"Down 40 pounds on semaglutide and sleeping badly, recovering worse. My provider reviewed all three options with me and started me on sermorelin. I tracked sleep, recovery, and training notes closely, and those were the markers I wanted support for most. The mechanism got me in the door. The provider-guided process is why I felt comfortable starting."
"I ran the comparison the way I run any engineering decision: a gentle single-pathway signal versus a dual-pathway one with longer IGF-1 elevation in human data. I chose CJC-1295/Ipamorelin with my provider's sign-off. Exogenous GH supplies growth hormone directly; this route works upstream through growth-hormone signaling. My provider explained the difference, reviewed my history, and monitored the protocol. My recovery metrics are what I watch most closely."
"The scale hit goal months before the waistline did. I am the patient who reads the prescribing information, so I already knew tesamorelin had actual visceral-fat trial data behind it. My provider agreed it fit my case. Six months in, I'm tracking the waistline with the same seriousness I tracked the scale. That is the kind of body-composition conversation I wanted my provider to review."
No insurance battles. No six-week referral wait. No overseas roulette.

If our provider determines a secretagogue isn't right for you, you pay nothing. Zero. You'll still walk away knowing exactly where you stand — and what your real options are.
A secretagogue is a signal, not a supply. Instead of injecting growth hormone itself, these peptides signal your pituitary gland to release more of your body's own natural growth hormone, in the pulsatile pattern your body already uses, with the feedback loop intact. Sermorelin and tesamorelin are GHRH analogs. CJC-1295/Ipamorelin pairs a GHRH analog with a ghrelin mimetic for a dual-pathway signal. All three are prescription medications; sermorelin and CJC-1295/Ipamorelin are compounded, and compounded medications are not FDA-approved.
You don't have to — that's the provider's job. The short version: sermorelin is the gentle, well-documented starting signal (sleep, recovery, lean-mass baseline). CJC-1295/Ipamorelin is the stronger, longer dual-pathway signal. Tesamorelin is the body-composition specialist with visceral-fat trial data. Which one fits depends on your goals, training, health history, and current medications — which is exactly what the $0 eligibility review evaluates.
That is the combination this page is about: one medication supporting weight loss, and one provider-reviewed pathway that may support lean tissue, recovery, and sleep quality. They act on different pathways. Whether the combination is appropriate for you depends on your health history, current medications, and contraindications, which is what the provider review is for. Never combine prescription medications without a clinician's guidance.
Taking growth hormone means injecting exogenous GH, which supplies the hormone directly and can suppress your body's own production through negative feedback. Secretagogues work upstream: they signal your pituitary to release your own GH, in pulses, with the feedback loop intact. Because secretagogues work upstream, growth-hormone release remains subject to the body's normal feedback pathways. For patients looking to discuss lean-tissue support, recovery, and sleep quality, that upstream route is the mechanism our providers review for appropriateness.
Many patients tolerate these protocols well, but side effects and contraindications vary by molecule and medical history. The most commonly reported effects across the class are mild injection-site reactions, flushing, or headache. CJC-1295/Ipamorelin may also cause temporary water retention, tingling, or increased hunger in some patients. Tesamorelin may cause injection-site reactions, joint aches, or tingling, and can affect blood sugar, which your provider considers when reviewing your history. The provider review exists precisely to screen for contraindications and determine whether any of these is appropriate for you; this is not a decision to crowdsource from a forum.
Because "for research purposes only" means "not for human use." Unknown purity. Unknown dosing. No clinician if something goes wrong. No recourse if the vial is garbage. You of all people know that an unverified input makes the whole system unreliable. This program exists so you never have to roll those dice: a licensed provider, a licensed U.S. pharmacy, and a real medical record.
Your GLP-1 is built for the weight-loss side of the equation. Three minutes is all it takes to find out which secretagogue a licensed provider may consider for your case — whether that means baseline support, a stronger GH/IGF-1 signal, or a visceral-fat-focused option. You wanted the comparison. Now you have it — reviewed by a real clinician, at $0 today.
