Buy HGH Injection Pen 120iu — Synedica Somatotropin Research Pen Kit
The Synedica Somatotropin HGH 120iu Injection Pen Kit is the most advanced way to buy an HGH injection pen for structured human growth hormone research. Pre-loaded, precision-dosed, and ready to use the moment it arrives — no reconstitution, no bacteriostatic water, no vial measuring required.
Somatotropin is a synthetic recombinant form of human growth hormone (HGH) with an identical 191-amino acid sequence to naturally produced pituitary HGH. In controlled laboratory and R&D settings it is one of the most extensively studied peptide hormones in existence — investigated for its role in IGF-1 stimulation, cellular proliferation, lipid metabolism, nitrogen retention, and anabolic signaling pathways. The Synedica pen kit delivers this compound in a convenient, repeatable pen format specifically designed for structured multi-week research protocols.
Why Buy the Synedica HGH Injection Pen Kit?
Most research-grade HGH is sold as lyophilized powder vials requiring reconstitution with bacteriostatic water, separate insulin syringes, and precise IU measurement before every administration. The Synedica HGH injection pen removes every one of those steps — delivering pre-measured IU doses from a single pre-loaded cartridge with consistent accuracy across every administration.
- 120iu total per kit — 2 pre-loaded 60iu pens, the highest IU pen format available for research
- 191-amino acid sequence — identical structure to endogenous pituitary human growth hormone
- Precise IU dose increments — 1iu, 2iu, 3iu, 4iu, and 5iu per administration
- Everything included — 2 pens, 12 disposable 32g 4mm needles, full dosing guide booklet
- No reconstitution — no bacteriostatic water, no insulin syringes, no vial measuring needed
- Fast USA shipping — in stock, dispatched within 1 business day
Dose Configuration & Research Protocol Guide
The Synedica Somatotropin pen is configurable across a range of IU doses to suit different research protocol designs. The standard escalation protocol for new research applications begins at 1–2iu per administration, gradually increasing based on protocol requirements. Each pen delivers 60iu total — the two-pen kit provides 120iu, supporting an extended multi-week research window.
| Dose Setting | HGH per dose | Doses per pen | Doses per kit |
|---|---|---|---|
| 1iu | 1iu Somatotropin | 60 doses | 120 doses |
| 2iu | 2iu Somatotropin | 30 doses | 60 doses |
| 3iu | 3iu Somatotropin | 20 doses | 40 doses |
| 4iu | 4iu Somatotropin | 15 doses | 30 doses |
| 5iu | 5iu Somatotropin | 12 doses | 24 doses |
What Is Somatotropin (HGH)?
Somatotropin — also known as human growth hormone (HGH) or somatropin — is a 191-amino acid single-chain polypeptide synthesised and secreted by somatotropic cells in the anterior pituitary gland. Its molecular formula is C990H1529N263O299S7 with a molecular weight of approximately 22,124 daltons.
In laboratory research settings, somatotropin is investigated for its role in stimulating the liver to produce insulin-like growth factor 1 (IGF-1), which mediates many of HGH’s downstream anabolic and metabolic effects. Research applications include the study of cellular proliferation signalling, lipolysis pathway modulation, nitrogen retention, protein synthesis stimulation, and the interaction between GH and GH receptor binding in preclinical models.
The Synedica Somatotropin pen kit uses a recombinant synthetic form with the same 191-amino acid sequence as endogenous pituitary HGH — distinguishing it from 192-amino acid variants that carry a methionine prefix associated with increased antibody response in research models.

Frequently Asked Questions
Where can I buy an HGH injection pen?
The Synedica Somatotropin HGH 120iu Injection Pen Kit is available directly at synedica.us. It is one of the only pre-loaded HGH injection pens available to buy online for research applications — no reconstitution required. In stock with fast USA shipping.
What is the difference between Somatotropin and Somatropin?
Somatotropin and somatropin refer to the same compound — recombinant human growth hormone with an identical 191-amino acid sequence to endogenous pituitary HGH. Somatropin is the INN (International Nonproprietary Name) used in pharmaceutical contexts; somatotropin is the naturally occurring form name. The Synedica pen uses a synthetic recombinant 191-amino acid sequence identical to both.
How many IU does the Synedica HGH injection pen kit contain?
The kit contains 2 pre-loaded pens of 60iu each — 120iu total per kit. At a 2iu daily research protocol the kit supports 60 administrations. At 4iu it supports 30 administrations across the full two-pen kit.
Does the HGH injection pen require reconstitution?
No. Unlike lyophilized HGH powder vials that require reconstitution with bacteriostatic water and separate insulin syringes, the Synedica HGH injection pen is pre-loaded and ready to use — no preparation steps required.
What is the amino acid sequence of the Somatotropin in this pen?
The Synedica Somatotropin uses a synthetic recombinant 191-amino acid sequence — identical to endogenous pituitary human growth hormone. This distinguishes it from 192-amino acid methionyl-HGH variants used in some early research formulations.
How is the Synedica HGH pen kit different from HGH vials?
Standard research-grade HGH vials require reconstitution with bacteriostatic water, precise IU measurement with insulin syringes, and careful mixing technique before every administration. The Synedica buy HGH injection pen format delivers accurate pre-measured IU doses at the dial of a pen — eliminating preparation variables and making it the most consistent format for structured multi-week HGH research protocols.
What is IGF-1 and how does HGH relate to it in research?
In preclinical research models, somatotropin (HGH) stimulates hepatic production of insulin-like growth factor 1 (IGF-1), which acts as the primary mediator of HGH’s downstream anabolic and metabolic effects. Research investigating GH/IGF-1 axis signalling commonly uses recombinant somatotropin such as the Synedica 191-amino acid pen formulation as the primary test compound.
