Description
HGH Research Kit (1 kit of 10 × 10iu)
Bulk pack of human growth hormone (somatropin), recombinant 191-amino-acid polypeptide. This kit contains 10 × 10iu vials (100iu total) of lyophilized hGH.
Mechanism of Action (Research Context)
Somatropin is identical to the 191-aa human pituitary growth hormone. It binds the growth hormone receptor on multiple tissues, activating JAK2/STAT5 signaling and driving hepatic IGF-1 production, which mediates most of its systemic effects (Chikani & Ho, J Mol Endocrinol, 2014).
Compound Properties (per vial)
- Compound: Somatropin (recombinant human growth hormone, 191 aa)
- Molecular Weight: ~22,124 Da
- CAS Number: 12629-01-5
- Kit Contents: 10 × 10iu vials (100iu total ≈ 33.3 mg)
- Purity: ≥98% (HPLC / SDS-PAGE)
Research-Reference Dosing
Clinical reference ranges vary widely by indication. In adult growth hormone deficiency trials, doses commonly range from 0.15 – 0.30 mg/day SC (~0.5 – 1 iu/day), titrated by IGF-1 response (Molitch et al., J Clin Endocrinol Metab, 2011). Higher doses have been referenced in research contexts.
What the Kit Includes
- Lyophilized peptide vials (see quantities below)
- Syringes (insulin-gauge)
- Alcohol prep pads
- Reconstitution solution
- Mixing syringe
Add $15 if you want us to reconstitute your vials before shipping.
Research Findings
- FDA-approved for GH deficiency, Turner syndrome, chronic renal insufficiency in pediatric growth failure, AIDS wasting, and other indications.
- Established effects on body composition: lean mass gain, fat mass reduction, bone density changes over 6-12 months.
- Strong clinical evidence base compared to most research peptides.
Known Side Effects Reported in Trials
- Peripheral edema, arthralgia, myalgia
- Carpal tunnel syndrome (dose-related)
- Glucose intolerance / new-onset diabetes in susceptible subjects
- IGF-1 elevation requires monitoring; long-term neoplasia concerns are discussed in the literature
Storage & Handling
- Unopened lyophilized vials: refrigerate at 2-8 °C; long-term storage at −20 °C recommended. Protect from light.
- After reconstitution: refrigerate at 2-8 °C and use within 14-28 days per standard peptide stability guidance.
- Avoid repeated freeze-thaw cycles of reconstituted material.
Shipping
UPS 2-Day shipping: $7 Texas / $12 out of state / $35 for ICE (insulated cold pack).
