Information for institutional quotation
HGH Fragment 176-191: price, documentation and dispatch in Colombia
HGH Fragment 176-191 is listed in this catalog as a peptide reference intended exclusively for research and laboratory work, classified as the C-terminal 176-191 fragment of somatropin. That means it is not the full hormone but the specific region occupying that position within the somatropin sequence, within the growth hormone and secretagogues category. This page brings together the two available presentations, the current price shown in the commercial block, and the documentary conditions for an institutional quote. The identity and purity of the lot are not assumed from the name or the declared sequence position; they are confirmed by the certificate of analysis Janoshik Analytical issues per lot, using HPLC for purity and mass spectrometry for identity. This page explains what it means to be a C-terminal fragment and how this reference is positioned relative to others on the same growth axis.

What 'C-terminal 176-191 fragment' means
The catalog classifies this reference as the C-terminal 176-191 fragment of somatropin. 'C-terminal' indicates that the fragment corresponds to the tail end of the full hormone's chain, and '176-191' marks the exact amino acid positions that region spans within somatropin's complete sequence. This page documents that declared structural location without describing what function that region performs within the full hormone.
Being a fragment means the molecule is shorter than the hormone that region comes from. The catalog does not declare that this fragment reproduces all the properties of complete somatropin; it is limited to identifying which protein and which exact position it comes from, which is the verifiable structural information available for this reference.
Structural relationship to complete somatropin
Somatropin is the growth hormone from which this 176-191 region is declared. This page does not offer a description of the complete hormone or its role in an organism; it is limited to documenting that the fragment corresponds to that specific position, which is a structural classification fact, not an analytical fact about a specific lot.
The catalog has another reference related to the same region: AOD9604, which the catalog describes as a modified 176-191 fragment of somatropin. The difference between the two is that HGH Fragment 176-191 is declared as the fragment without the additional modification AOD9604 does carry. That distinction should be clear in any institutional request involving either reference.
Two presentations and their physical form
HGH Fragment 176-191 is available in two presentations, 2 mg and 5 mg, both measured by mass and corresponding, under the catalog's criterion, to a lyophilized powder in a vial. Choosing between them is a commercial decision that should be stated with the corresponding code in the institutional request, without that changing the declared C-terminal fragment structural classification for this reference.
The current price for each presentation is shown in the commercial block of this page. Within the growth hormone and secretagogues category, this reference shares commercial space with other catalog entries, such as ACE-031, a fusion protein with a structural classification distinct from a peptide fragment.
Identity and purity: the scope of the Janoshik COA for a fragment
The certificate of analysis for HGH Fragment 176-191 is issued by Janoshik Analytical, per lot, using HPLC for purity and mass spectrometry for identity. For a peptide fragment like this one, mass spectrometry is particularly relevant to confirm the material corresponds to the declared 176-191 region, and not to the full hormone or to the modified AOD9604 variant. The COA is arranged on request and subject to documentary availability.
No analytical figure for this reference is filled in by analogy: this page does not state a purity percentage, a CAS number, a molecular formula, or a molecular weight, because none of those are verified in the documentation available. The COA is provided on request and subject to documentary availability, and it is the document where those fields should be read, always referring to the lot dispatched.
Storing a lyophilized peptide fragment
Custody conditions come from the documentation that accompanies the lot, not from this page. When that document sets 2-8 °C and protection from light, the receiving institution needs to have the refrigerated space ready before arrival, with the 2 mg and 5 mg presentations distinguished in the intake record.
Handling is on a made-to-order basis, with a 15-day coordination window that should be factored into the purchase timeline. Shipping fees for Bogota and for the rest of the country are set out on the site's shipping information page; the delivery date is confirmed during the institutional quote and is not stated here in advance. 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.
This fragment versus other references on the GH axis
Within the growth hormone and secretagogues category, HGH Fragment 176-191 is distinguished from AOD9604 by not carrying the additional modification that second reference does declare, and from ACE-031 by belonging to a different structural class: a peptide fragment versus a fusion protein. Documenting these differences helps an institutional request identify precisely which growth-axis reference it needs to quote.
The sequence is: request recorded, quote confirmed in writing, and payment coordinated at the end. The file worth keeping brings together those three documents along with dispatch confirmation, the receiving record, and Janoshik's certificate for the lot, if one was requested.
Frequently asked questions about HGH Fragment 176-191
What does it mean that HGH Fragment 176-191 is a C-terminal fragment?
That it corresponds to the final region of somatropin's sequence, between positions 176 and 191, and not to the full hormone. It is a declared structural classification from the catalog.
How does it differ from AOD9604?
Both references correspond to the same 176-191 region of somatropin, but AOD9604 is declared as a modified version of that fragment, while HGH Fragment 176-191 is declared without that modification.
And from ACE-031, in the same category?
ACE-031 is a fusion protein of the activin type IIB receptor, a structural class distinct from a peptide fragment like HGH Fragment 176-191. They share a commercial category, not a structural classification.
Who certifies this reference's lot?
Janoshik Analytical, per lot, using HPLC for purity and mass spectrometry for identity. The certificate is arranged on request and subject to documentary availability.
How is HGH Fragment 176-191 stored?
Per the documentation applicable to the lot. If it specifies 2-8 °C and protection from light, that condition should be built into the laboratory's custody setup before receiving the package.
