Ipamorelin 5mg for Sale | 99% Pure Selective Growth Hormone Secretagogue

The older growth-hormone-releasing peptides had a problem: they didn’t just release growth hormone, they also spiked cortisol and prolactin, dragging unwanted hormonal noise into every experiment. Ipamorelin solved that. It was characterized as the first selective growth hormone secretagogue — a peptide that prompts the pituitary to release GH while leaving cortisol, prolactin, and aldosterone essentially untouched (Raun et al., 1998). That clean signal is the entire reason it became a go-to research tool.

Ipamorelin 5mg is the high-purity, research-grade form of that pentapeptide — verified 99%+ pure, lyophilized, and built for precise pituitary and metabolic research. If your work depends on isolating the GH pathway without a tangle of off-target hormone effects confounding your data, this is the compound designed for exactly that. Here’s how it works, how to handle it, and where to buy it.

What Makes Ipamorelin “Selective”

Ipamorelin is a pentapeptide — just five amino acids, sequence Aib-His-D-2-Nal-D-Phe-Lys-NH₂ — that acts as a ghrelin mimetic. It binds the growth hormone secretagogue receptor (GHS-R1a), the same receptor the hunger hormone ghrelin uses, and triggers a pulse of growth hormone release from the pituitary.

The word that matters, though, is selective. Earlier GHRPs like GHRP-6 stimulated GH but also raised cortisol, prolactin, and appetite through less discriminating receptor activity. Ipamorelin was engineered to hit GHS-R1a cleanly, producing a GH pulse without meaningfully disturbing cortisol, prolactin, or aldosterone. For a researcher, that selectivity is gold — it means the growth-hormone response you’re measuring isn’t contaminated by a stress-hormone response you didn’t want. That clean, well-defined profile is why Ipamorelin shows up in so much pituitary-function research.

How Ipamorelin Works

The mechanism is straightforward and elegant. Ipamorelin binds GHS-R1a on the pituitary somatotroph cells and stimulates growth hormone release — while also suppressing somatostatin, the hormone that normally puts the brakes on GH. Two levers, one direction. Importantly, because it works with the body’s own pulsatile machinery rather than flooding the system, it preserves the natural rhythm of GH secretion rather than flattening it.

This is also why Ipamorelin is so often studied alongside a GHRH analog like CJC-1295. The two act on different receptors — GHRH analogs prime GH production, while Ipamorelin triggers and amplifies its release — so researchers pair them to study additive, more physiological GH pulses. On its own, though, Ipamorelin is the cleaner tool for isolating GHS-receptor signaling specifically.

Where Ipamorelin 5mg Fits in Research

An honest note: Ipamorelin‘s selectivity and mechanism are well-characterized in preclinical and pharmacology research, but it isn’t an approved therapeutic — the data describes how the peptide behaves in models, not a validated clinical use.

The GLP1 Peptides Quality Standard

For a five-residue peptide with two D-amino acids (D-2-Nal, D-Phe) that are central to its selectivity, that COA confirms you have genuine Ipamorelin — correct sequence, correct stereochemistry, not a cheaper substitute.

How to Reconstitute Ipamorelin 5mg — Step by Step

Handling is what separates reliable Ipamorelin data from wasted material. Here’s the full walkthrough.

Concentration guide (5mg vial): add 1 mL for 5 mg/mL, 2 mL for 2.5 mg/mL, or 5 mL for an easy 1 mg/mL — the more solvent, the finer your titration control.

How to Store Ipamorelin 5mg

• Lyophilized powder: -20°C, sealed, dark, and dry — stable long-term.
• Reconstituted solution: 2–8°C, protected from light, used within a few weeks.
• Freeze-thaw: avoid repeated cycles entirely — aliquot first.
• Inspect: a proper solution is clear and colorless; discard anything cloudy or discolored.

Cold, dark, gentle, aliquoted — the discipline that keeps a peptide reproducible from first draw to last.

Ipamorelin vs Other Growth Hormone Secretagogues

The clean takeaway: Ipamorelin is the selective, low-noise member of the secretagogue family. Where GHRP-6 and GHRP-2 drag along cortisol and prolactin, Ipamorelin keeps the signal clean — and where CJC-1295 works upstream on a different receptor, the two are complementary rather than competing.

FAQs about Ipamorelin 5mg

1. What is Ipamorelin 5mg? A 5mg vial of Ipamorelin, a selective pentapeptide growth hormone secretagogue (sequence Aib-His-D-2-Nal-D-Phe-Lys-NH₂), supplied as a lyophilized powder for pituitary and metabolic research.

2. What makes Ipamorelin “selective”? It stimulates GH release through GHS-R1a while leaving cortisol, prolactin, and aldosterone essentially unaffected — unlike older, less discriminating GHRPs. That clean profile is its defining feature.

3. How does Ipamorelin work? It’s a ghrelin mimetic: it binds GHS-R1a on the pituitary to trigger GH release while suppressing somatostatin (GH’s natural brake), preserving the body’s pulsatile secretion pattern.

4. Why is Ipamorelin studied with CJC-1295? Because they act on different receptors — CJC-1295 (a GHRH analog) primes GH production while Ipamorelin triggers its release — so pairing them produces additive, more physiological GH pulses.

5. How is Ipamorelin different from GHRP-6? GHRP-6 raises GH but also cortisol, prolactin, and appetite. Ipamorelin is far more selective, giving a clean GH pulse with minimal off-target hormone effects.

6. How do I reconstitute Ipamorelin 5mg? Warm the vial, sanitize the stopper, add bacteriostatic or sterile water slowly down the glass wall, swirl gently (never shake), then aliquot. Full steps and a concentration guide are above.

7. How should Ipamorelin be stored? Lyophilized powder at -20°C, sealed and dark; reconstituted solution at 2–8°C, protected from light, with freeze-thaw avoided.

8. Is Ipamorelin FDA approved? No. It’s research-only, not approved for human use.

9. Is Ipamorelin banned in sport? Growth hormone secretagogues fall under WADA’s S2 category and are prohibited in competitive sport.

10. What is the molecular weight of Ipamorelin? Approximately 711.9 g/mol, formula C₃₈H₄₉N₉O₅, CAS 170851-70-4.

11. What purity should Ipamorelin be? Aim for 99%+ verified by HPLC and Mass Spectrometry, with a lot-specific COA confirming sequence and stereochemistry. Ours ships with that.

12. Where can I buy Ipamorelin 5mg internationally? GLP1 Peptides ships research-grade, COA-verified Ipamorelin 5mg to the USA, Canada, Germany, and France in sealed lyophilized vials. See the shipping section above.
