Spectros 36 IU Pen (USA Domestic)

Spectros 36 IU Pen is a dual-chamber pen for delivery of 12 mg (36 IU) of lyophilized Somatropin 191AA (rDNA origin) and bacteriostatic water for reconstitution. Human Growth Hormone (HGH) is a peptide hormone that is naturally synthesized in the body by the pituitary gland and is indispensable for regulating growth, cell regeneration, and body composition.

Synthetic HGH, or somatropin, is commonly used to “top up” natural HGH levels. The Somatropin and bacteriostatic water are stored separately within the same device (Spectrum Pen 36 IU) until activated, which eliminates the need to prepare two separate vials and decreases preparation time in a closed system.

What Is the Spectros 36 IU Pen?

A pen injector is a compact and easy-to-use injection device used for giving a subcutaneous injection and includes a cartridge holder, dose dial, disposable needle, and protective casing. This format was originally created for insulin therapy purposes, but is suitable for most peptide medications, such as growth hormone.

This is the idea of the Spectros 36IU Pen for somatropin. The Somatropin 191AA rDNA is contained in one sealed unit with 12 mg (36 IU) plus bacteriostatic water, which is stored separately from the Somatropin 191AA until use. 

Pressing the activation mechanism will automatically cause both chambers to be merged, and the hormone will be mixed inside the machine. No additional vials, external diluent transfer, or syringe preparation is required, which maintains a quick and low-contamination process.

Dual-Chamber Pen Format and Package Contents

The Spectros 36 IU Pen is delivered in a single-chambered injector that contains both active ingredients and diluent. The two components remain physically separated within the pen until use, and maintain the stability of the lyophilized powder. The contents of each Unit are summarised below:

Specification	Details
Active substance	Somatropin 191AA
Origin	Recombinant DNA (rDNA) technology
Potency	12 mg (equivalent to 36 IU)
Diluent	Bacteriostatic water
Format	Dual-chamber cartridge pen
Chamber configuration	Powder and solvent kept separate
Delivery system	Integrated, pre-loaded, single sealed unit

Each pack of Spectros HGH pen includes an entire, pre-stored device – no extra ampoules or separate reconstitution kits are needed.

Spectros 36 IU Pen Price and Availability

For the most accurate Spectros 36 IU Pen Price, always check the live figure displayed on the official product card, since values are updated regularly to reflect current market conditions, currency rates, and supplier adjustments. 

The same applies to stock status: whether the Spectros HGH for sale listing shows the item as in stock, limited, or temporarily unavailable depends on real-time inventory. The current price as of October 2026 is $130, but it is subject to change. The same applies to inventory availability, so please keep this in mind before placing your order.

Packaging, Authenticity, and Product Verification

Each Spectrum Pharma HGH Pen is sealed in brand packaging with a batch number, manufacturing and expiration dates, a lot code, and a scratch-off or holographic verification label. The user removes the protective layer to see a code unique to the product, then types that code into the manufacturer’s verification site. 

A matching code batch/lot will be given back on the first scan from a genuine 36 IU HGH Pen; if the code is reported as “already used” or “invalid,” it is a clear indication that it is a counterfeit.

USA Domestic Shipping and Storage

In the USA, orders of Spectros 36 IU HGH pen pass through two stages: processing, which involves verification, packing, and quality control, and they are sent by a domestic courier. 

Processing times and delivery windows are tracked separately and should be confirmed on the order page before you buy Spectros 36 IU Pen. The storage requirements should be those specified on the manufacturer’s carton (usually +2°C – +8°C, away from light and freezing), and not any common site storage note. 

Frequently Asked Questions

What is the form of the Spectros 36 IU Pen?

It comes as a pre-filled, dual-chamber injector. The active substance and diluent are contained in a single sealed cartridge, so there are no extra vials, external solvent, or preparation kit in the standard pack.

What is the pen filled with?

Somatropin 191AA 12 mg (36 IU) is supplied with each unit containing both the Somatropin 191AA (12 mg/36 IU per unit) and the diluent (bacteriostatic water). The powder and solvent are kept in separate chambers in the same sealed pen until it is time to reconstitute them.

Where do I find authentic proof, and where do I find the current price and availability?

Authenticity is verified by the batch and lot code printed on the carton, and the scratch-off verification label whose code is verified on the manufacturer’s official portal (the URL on the carton is always the exact URL on the manufacturer’s official website). 

What are the storage and shipping conditions?

Store according to manufacturer’s label instructions – usually cool and light. Processing and transit are listed separately for USA shipping; check both on the order page.
