Ipamorelin was the first selective growth hormone secretagogue (Raun et al. 1998), distinguished from earlier GHRPs by minimal cortisol, prolactin, and aldosterone elevation at GH-active doses. That selectivity is the entire reason ipamorelin remains in active community use despite never reaching FDA approval — buyers tolerate the per-mg pricing premium over GHRP-2 and GHRP-6 because they don't get the cortisol bump.
Research-context information only. Ipamorelin is a research peptide. Protocols, doses, and reactions reported below come from published research and self-reported community sources. This article reports what has been documented, not what should be done. Consult a licensed physician for personal medical decisions.
This guide covers documented per-mg pricing, how to verify an ipamorelin COA, which vial size matches typical protocols, and red flags. For dosing itself, see the ipamorelin dosing guide.
Ipamorelin ships as a lyophilized powder in sealed glass vials. Three factors drive your per-mg cost: vial size (bigger = cheaper per mg), vendor markup, and whether the COA confirms 98%+ HPLC purity and 711.85 Da on mass spec.

How to Verify Ipamorelin Quality
Ipamorelin is a pentapeptide (Aib-His-D-2-Nal-D-Phe-Lys-NH2) with C-terminal amidation and two unnatural amino acids — alpha-aminoisobutyric acid (Aib) and 3-(2-naphthyl)-D-alanine (D-2-Nal). The unnatural residues are what give ipamorelin its receptor selectivity at GHS-R, and they're the synthesis steps where shortcuts can occur if vendors substitute cheaper L-amino acids.
What a COA Should Include
Identity Confirmation
Mass spectrometry confirming 711.85 Da for ipamorelin
Sequence verification — 5 residues with C-terminal amidation
D-2-Nal and Aib substitutions verified (chiral and unusual residues)
Purity Testing
HPLC purity at 98%+ (achievable for a 5-residue peptide)
Single dominant peak; secondary peaks indicate degradation
Ipamorelin reconstituted with bacteriostatic water and refrigerated is documented stable for roughly 28 days in published peptide-stability data. With sterile water (no preservative), the window collapses to ~24 hours.
Practical implication: A 10mg vial at 200mcg/day exceeds the 28-day window if reconstituted all at once. Common practice is staged reconstitution — pull from sealed lyophilized vial as needed, mixing only the volume needed for ~28 days at the user's specific daily dose.
Vial Size by Protocol
Tolerance testing context:
A 2mg or 5mg vial is the smallest unit for assessing tolerance before larger purchase
1-2 weeks at 200mcg/day
Standard 200-300mcg/day community protocol:
10mg vial — most-cited size for cost efficiency
Reconstituted in stages or used at higher daily doses to fit the 28-day window
1-3 vials per typical 8-12 week cycle
Higher-frequency 3×/day pulse-mimetic protocol:
10mg vial at 200mcg × 3 doses/day = 600mcg/day = ~17 days per vial
Fits inside the stability window cleanly

Why Ipamorelin Costs More Than GHRP-2 or GHRP-6
A common question: ipamorelin runs $4-8/mg while GHRP-2 sits at $2-4/mg and GHRP-6 is $1.50-3/mg. Two reasons:
1. Synthesis is harder. Ipamorelin contains two non-standard amino acids (Aib and D-2-Nal) that require specialized peptide chemistry. GHRP-2 and GHRP-6 use simpler residues.
2. Selectivity is the value.Trial data documented ipamorelin as the first selective growth hormone secretagogue — meaningfully clean of cortisol, prolactin, and aldosterone elevations at GH-active doses. GHRP-2 and GHRP-6 elevate cortisol and prolactin at higher doses. For users where cortisol matters (sleep quality, body composition during cuts), the selectivity is worth the per-mg premium.
When ipamorelin is paid for but mass spec shows ~817 Da (GHRP-2's molecular weight) or ~872 Da (GHRP-6), the buyer paid 2-3x for a less-selective peptide. The COA is what surfaces this.

Frequently Asked Questions
Is ipamorelin legal to buy?
Ipamorelin is sold as a research peptide labeled 'not for human consumption.' It is not FDA-approved. As of 2023, ipamorelin is on the FDA 503A bulks Category 2 list, meaning compounding pharmacies cannot legally produce it. Purchasing research peptides is legal in most US jurisdictions.
How much does ipamorelin cost per month?
At the most-cited 200-300mcg/day community protocol, monthly use runs 6-9mg. Research-vendor 5mg vials cost $25-50 and 10mg vials cost $40-80. Monthly cost ranges from $30-90 depending on vial size and dose.
What vial size should I buy — 5mg or 10mg?
10mg vials are slightly more efficient per mg ($4-8/mg vs $5-10/mg for 5mg vials) and last 30-50 days at standard doses, well within the 28-day reconstitution stability window. 5mg vials are common for tolerance testing or shorter cycles.
What purity should I look for in ipamorelin?
Third-party HPLC at 98%+ purity, plus mass spec confirming 711.85 Da. Ipamorelin is a pentapeptide (Aib-His-D-2-Nal-D-Phe-Lys-NH2) — relatively easy to synthesize, so legitimate vendors hit 98-99% purity routinely. Purity below 95% suggests degradation or improper handling.
Why is ipamorelin priced higher than CJC-1295?
Ipamorelin's two unnatural amino acids (D-2-Nal and Aib) require specialized peptide chemistry, increasing synthesis cost roughly 30-40% vs simpler peptides. CJC-1295 (no-DAC) uses standard L-amino acids in a 29-residue chain, which is paradoxically cheaper despite being longer.
Can I get ipamorelin from a compounding pharmacy?
Not legally as of 2024-2026. Ipamorelin is on the FDA 503A Category 2 bulks list. Some clinics still offered ipamorelin through 2023, but legitimate compounding has tightened. Research vendors are the documented option for buyers in this category.
