HGH 191AA (Somatropin): price, documentation and dispatch in Colombia
HGH 191AA (Somatropin) is in Peptidos Colombia's catalog as a research and laboratory-work reference. Technically, it is a 191-amino-acid recombinant somatropin, the complete molecule of the GH/IGF-1 axis within this technical category, which also includes its own 176-191 fragment and several secretagogues and GHRH analogs. Its presentation is 36 IU, the only one in this category declared in international units rather than milligrams. Lot identity and purity are confirmed by the certificate of analysis issued by Janoshik Analytical, per lot, with HPLC for purity and mass spectrometry for identity, upon institutional request, subject to the lot's documentary availability. This listing brings together classification, presentation, documentation, storage, and logistics without proposing any use outside the research framework. The catalog code associated with this 36 IU presentation is HGH36, additional information that helps identify it in any quote covering several references from the same axis.

HGH 191AA: the complete 191-amino-acid somatropin
The 191-amino-acid recombinant somatropin is the complete sequence of human growth hormone produced through recombinant technology, as the technical catalog declares it. This classification distinguishes HGH 191AA from its own fragment, HGH Fragment 176-191, which corresponds only to the C-terminal end of the same protein and is sold as a separate reference.
The name HGH 191AA (Somatropin) should be recorded in full in any institutional request, including the parenthetical, to distinguish it unambiguously from other GH/IGF-1 axis references that also contain the letters HGH in their catalog description.
The only reference in its category declared in IU
While the rest of the GH/IGF-1 axis references are presented in milligrams — from hexapeptide secretagogues to GHRH analogs — HGH 191AA is declared in international units: 36 IU. This difference in unit of measurement is verifiable catalog data, characteristic of how recombinant proteins are standardized compared with short-chain synthetic peptides.
For an institutional quote combining HGH 191AA with other references from the same axis declared in milligrams, it is worth keeping each one's unit as it appears on its listing, without converting it, since the catalog does not publish an equivalence between international units and milligrams for this reference.
Complete molecule versus its own 176-191 fragment
HGH Fragment 176-191 corresponds only to the C-terminal end of somatropin, while HGH 191AA declares the complete 191-amino-acid sequence. Both references coexist in the catalog under the same technical category, and the difference between them is one of sequence length, a structural fact rather than an editorial preference of this listing.
That distinction matters when requesting a quote: naming the complete reference keeps the order from being confused with the fragment, which has its own listing, its own presentation, and its own price within the same technical catalog.
What the Janoshik Analytical COA certifies in this case
HGH 191AA's certificate of analysis is issued by Janoshik Analytical, per lot, with HPLC for purity and mass spectrometry for identity. Being a recombinant protein larger than a short synthetic peptide, matching the document to the physical lot received is, if anything, even more worth verifying, though the documentary procedure is the same as for the rest of the catalog.
This listing does not publish a purity figure or a complete amino-acid sequence, because those analytical data depend on the specific lot and are requested subject to documentary availability. CAS number, molecular formula, and molecular weight remain visibly pending until specific support exists.
Cold storage and delivery logistics
HGH 191AA's storage follows the documentation applicable to the lot, currently stated as 2–8 °C, protected from light, the same criterion the catalog applies to the rest of its protein and peptide references. The receiving institution should have that space available before the shipment arrives, with a record identifying the received lot from the first moment.
Shipping rates to Bogotá and to other destinations within the country are shown on the site's shipping information page. Delivery time is confirmed at the time of the quote, according to destination, and is kept as a value independent of the reference's price. Outside Colombia, this reference ships to 5 countries (Costa Rica, Ecuador, United States, Mexico and Puerto Rico), from US$57; the rate for each country is listed on the site's international shipping page.
From the quote to a documented receipt
An order for HGH 191AA is logged, confirmed in writing in an institutional quote, and only afterward is payment coordinated using the method defined there. Before paying, the buyer can review the full name, the IU presentation, the current price, and the shipping destination.
Upon receiving the package, the reference and presentation are checked against the quote, the visible lot is logged, and the COA is kept when it was requested. The complete file makes it possible to reconstruct the transaction without relying on scattered messages.
Frequently asked questions about HGH 191AA (Somatropin)
What is HGH 191AA (Somatropin)?
A 191-amino-acid recombinant somatropin, the complete sequence of this protein within the catalog. It is offered exclusively for research and laboratory work.
How does it differ from HGH Fragment 176-191?
HGH 191AA is the complete 191-amino-acid sequence; HGH Fragment 176-191 is only the C-terminal end of the same protein. They are separate catalog references.
Why is it presented in IU rather than mg?
It is the only reference in its category declared in international units, the usual way of standardizing this recombinant protein compared with synthetic peptides measured in milligrams.
Who certifies the lot's identity and purity?
Janoshik Analytical, per lot, with HPLC for purity and mass spectrometry for identity, upon institutional request, subject to the lot's documentary availability.
How is this reference stored?
According to the documentation applicable to the lot, currently in a range of 2–8 °C, protected from light.
What catalog code corresponds to this presentation?
HGH36, associated with the 36 IU presentation. That code helps identify the exact reference in an institutional quote with several lines from the same GH/IGF-1 axis.
