Ipamorelin is a synthetic pentapeptide with the sequence Aib-His-D-2Nal-D-Phe-Lys-NH2, classified as a selective growth hormone secretagogue (GHS) and ghrelin receptor agonist. The 5mg vial format represents a standard medium-throughput laboratory quantity, providing sufficient material for multi-day in vitro assays or ongoing rodent model studies without requiring frequent re-solubilization.
Supplied as a sterile, vacuum-sealed lyophilized cake, each 5mg unit from PX1 Research is formulated with minimal excipients to ensure rapid, clear reconstitution and consistent batch-to-batch molarity. Laboratories sourcing this scale often balance unit volume requirements with long-term peptide stability, ensuring that prepared stock solution aliquots meet strict experimental timelines.

In preclinical investigations, Ipamorelin binds selectively to the growth hormone secretagogue receptor (GHS-R1a) present on pituitary somatotropes and central neuronal circuits. Unlike earlier-generation secretagogues, animal study data indicate that Ipamorelin stimulates somatotroph signaling to induce a dose-dependent, pulsatile release of growth hormone (GH) without inducing significant secondary surges in adrenocorticotropic hormone (ACTH), cortisol, or prolactin.
This exceptional selectivity makes Ipamorelin a foundational model compound in endocrinology and metabolic research. Preclinical data suggest that the maintenance of baseline cortisol and prolactin pathways prevents confounding systemic stressors in longitudinal animal trials, allowing researchers to isolate somatotropic pathways, IGF-1 transcription rates, nitrogen retention, and skeletal muscle metabolic parameters.
Accurate concentration calculations are vital for consistent experimental dosing and volumetric micro-pipetting. Reconstituting a 5mg (5,000 mcg) lyophilized vial with bacteriostatic water or sterile standard diluent yields predictable concentrations based on the liquid volume added.
Below are the foundational mathematical breakdowns for standard laboratory diluent volumes introduced to a 5mg vial of Ipamorelin:
• 1.0 mL Diluent Addition: 5.0 mg / 1.0 mL = 5.0 mg/mL (5,000 mcg/mL). Every 0.01 mL (1 unit on a standard 100-unit laboratory micro-syringe) delivers exactly 50 mcg of active peptide.
• 2.0 mL Diluent Addition: 5.0 mg / 2.0 mL = 2.5 mg/mL (2,500 mcg/mL). Every 0.01 mL delivers exactly 25 mcg of active peptide.
• 3.0 mL Diluent Addition: 5.0 mg / 3.0 mL = 1.67 mg/mL (1,666.7 mcg/mL). Every 0.01 mL delivers approximately 16.67 mcg of active peptide.
For quick field verification of custom diluent volumes or alternative micro-molar conversions, researchers are encouraged to utilize the PX1 interactive reconstitution-calculator.
Once solubilized, peptide stability rapidly degrades if subjected to repeated freeze-thaw cycles or ambient thermal fluctuations. In vitro assay setups requiring precise nanomolar concentrations must account for accurate volumetric aliquoting immediately following initial reconstitution.
Researchers should use low-binding polypropylene micro-centrifuge tubes to freeze secondary aliquots at -20°C or -80°C. Working solutions should be kept under refrigeration at 2°C to 8°C and utilized within a strict laboratory shelf-life window. Avoiding glass surface adsorption and minimize headspace air exposure ensures maximum target concentration retention over multi-week research protocols.
Unopened, lyophilized 5mg vials of Ipamorelin should be stored at -20°C in a dry, dark environment to maintain structural integrity for up to 24 months. If kept at ambient room temperature (20°C to 25°C), lyophilized vials remain stable for short transit windows, but long-term exposure risks peptide bond cleavage and oxidation.
Following reconstitution with preserved diluent (such as 0.9% benzyl alcohol bacteriostatic water), the liquid solution remains stable at 2°C to 8°C for approximately 28 days. Avoid ultrasonic bath agitation or violent mechanical shaking during dissolution; gentle vial rotation is recommended to preserve delicate tertiary interactions.
PX1 Research enforces strict quality assurance protocols for every manufactured batch. Every 5mg fill size undergoes rigorous identity and purity validation in an ISO 17025 accredited laboratory prior to release.
Purity is verified via High-Performance Liquid Chromatography (HPLC) to confirm a minimum threshold of 99.0%. Mass Spectrometry (MS) is simultaneously performed to verify exact molecular weight matching theoretical values. Furthermore, limulus amebocyte lysate (LAL) testing guarantees endotoxin levels fall strictly below standard research safety thresholds (<0.05 EU/mg).

When designing comparative endocrine or tissue regeneration assays, investigators frequently evaluate multiple growth hormone secretagogues alongside one another. Ipamorelin is distinct within its class due to its clean receptor affinity profile compared to first- and second-generation GHS compounds.
For example, GHRP-2 exhibits strong GH releasing potential but triggers modest elevations in plasma ACTH and prolactin in animal models. Similarly, Hexarelin demonstrates robust short-term GH elevation but may induce rapid receptor desensitization upon repeated administration. When researchers evaluate synergy, Ipamorelin is frequently paired in preclinical models with GHRH analogs such as CJC-1295 No DAC to observe dual-receptor somatotroph activation.

Determining whether a 5mg vial format is ideal depends on your laboratory's project scale, subject cohort size, and protocol duration. A 5mg format offers an optimal balance between unit economy and solution freshness for medium-scale rodent cohorts or multi-plate cell culture assays.
If your study protocol calls for small pilot evaluations, a smaller 2mg format may reduce potential waste from unused reconstituted liquid. Conversely, high-throughput screening initiatives or long-term multi-animal longitudinal projects benefit from scaled ordering.

What is the exact net weight of peptide in an Ipamorelin 5mg vial?
Each vial contains a certified minimum of 5.0 milligrams of high-purity lyophilized Ipamorelin peptide, verified by quantitative HPLC assay.
How is the 5mg Ipamorelin reconstituted for precise micro-pipetting?
Inject a known volume of sterile diluent (e.g., 1.0 mL, 2.0 mL, or 3.0 mL) through the rubber stopper using sterile laboratory technique, allowing the lyophilized cake to dissolve naturally without mechanical shaking.
Does PX1 supply a batch-specific COA for the 5mg size?
Yes. Every production run is tested by an independent ISO 17025 lab. Lot-matched COAs featuring HPLC purity profiles, Mass Spec identity verification, and endotoxin assays are available on our COA page.
What diluent should be used for long-term multi-dose animal studies?
0.9% Bacteriostatic Water (containing benzyl alcohol) is typically utilized for multi-entry reconstituted storage over 28 days under refrigeration. For immediate single-day assays, unpreserved sterile 0.9% saline or water for injection is standard.
How long is reconstituted Ipamorelin stable at 4°C?
When reconstituted with bacteriostatic water and held at 2°C to 8°C, solution integrity is maintained for up to 28 days. Lyophilized powder stored at -20°C remains stable for up to 24 months.
Why select Ipamorelin over GHRP-6 or Hexarelin for secretagogue research?
Preclinical studies show Ipamorelin selectively targets the GHS-R1a receptor without driving secondary cortisol or prolactin spikes, providing a cleaner baseline for isolating growth hormone dynamics.
What are the endotoxin limits on PX1 Ipamorelin vials?
PX1 research peptides are batch-tested to ensure endotoxin levels measure strictly below <0.05 EU/mg, preventing lipopolysaccharide-induced inflammatory interference in sensitive assays.
