Follistatin: price, documentation and dispatch in Colombia
Follistatin is listed at Péptidos Colombia as a laboratory reference for research, within the catalog's GH/IGF-1 axis and secretagogue group. Unlike most references in that group, which are short peptides, Follistatin is technically an activin-binding glycoprotein: a molecule of greater size and structural complexity. Its presentation is declared at 1 mg, a mass scale much smaller than that of the peptide secretagogues in the same group. This page explains that classification, the group of twelve references it belongs to, the correct reading of its presentation and price, and the documentation that backs each lot.

Follistatin as an activin-binding glycoprotein
The catalog describes Follistatin as an activin-binding glycoprotein. That classification sets it apart from the GHRH analogs and hexapeptide secretagogues that dominate the GH/IGF-1 axis: while those are short-chain peptides with a sequence of a few amino acids, a glycoprotein like Follistatin has a considerably larger structure with glycosylation modifications.
This page describes only that structural classification. It does not indicate a mechanism of action in an organism or a bodily result associated with Follistatin; the content is limited to name, family, presentation, reference price, and verifiable documentary conditions.
Its place in the GH/IGF-1 axis and secretagogues
The site's curated category groups Follistatin together with ACE-031, CJC-1295 With DAC, the CJC-1295 without DAC + Ipamorelin combination, GHRP-2 Acetate, GHRP-6 Acetate, HGH 191AA (Somatropin), HGH Fragment 176-191, Hexarelin Acetate, IGF-1LR3, Sermorelin Acetate, and Tesamorelin (Tesmorelin): twelve references that act at different points of the same signaling axis, according to their own structural classification.
Within that group, Follistatin shares a particular trait with ACE-031: neither is a short-chain peptide. ACE-031 is a fusion protein based on the activin receptor type IIB, and Follistatin binds directly to activin. Both descriptions concern molecular classification, not effect.
1 mg presentation: why it is not comparable in milligrams to a short peptide
Follistatin comes in 1 mg vials. Because it is a mass, its physical form is lyophilized powder in a vial. That milligram amount is not comparable, in terms of quantity of material, to a hexapeptide secretagogue such as GHRP-2 Acetate or Hexarelin Acetate, which come in 5 or 10 mg: the difference in scale reflects the molecular complexity of each compound class, not a shared unit of measure.
Follistatin's current price is shown in this page's commercial block and must be confirmed there before approving any quote, without assuming it matches another reference in the GH/IGF-1 axis or an earlier inquiry.
Follistatin versus ACE-031: two glycoproteins in the same axis
Follistatin and ACE-031 are the two references in the GH/IGF-1 axis that are not short-chain peptides. Follistatin is a glycoprotein that binds to activin; ACE-031 is a fusion protein that reproduces the activin receptor type IIB joined to an Fc fragment. Both relate structurally to the activin pathway, each from a different point: ligand binding in one case, receptor mimicry in the other.
This comparison is limited to the structural classification published by the catalog. Neither page describes an effect in an organism or a use indication; both are offered exclusively as laboratory reference material for research.
Documentary verification of Follistatin by Janoshik Analytical
The certificate of analysis (COA) for each lot of Follistatin is issued by Janoshik Analytical, with purity reported by HPLC and identity confirmed by mass spectrometry (MS). Being a glycoprotein and not a simple synthetic peptide, documentary verification of the lot is, if anything, more relevant than for more directly synthesized references.
The COA is handled on request and subject to documentary availability. This page does not publish a purity figure of its own for Follistatin, nor does it fill in CAS number, formula, or molecular weight: those data, when needed, are requested and verified against the certificate of the specific lot to be shipped.
Custody, shipping, and payment confirmation
Follistatin is stored according to the documentation applicable to the lot; if it specifies 2–8 °C and protection from light, those conditions must be built into custody before shipping. Rates for shipping to Bogotá and nationwide are shown on the site's shipping information, with times confirmed at the time of quote. 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.
The purchase sequence begins with registering the request; the written quote follows, setting Follistatin's presentation, price, and shipping, and only once those figures are set is payment coordinated through the method indicated there. For internal traceability, it helps to file the quote, the payment record, the shipping confirmation, and, if requested, the lot's certificate together.
Frequently asked questions about Follistatin
Is Follistatin a peptide?
Not in the sense of a short synthetic peptide. It is an activin-binding glycoprotein, larger and more complex than most references in the catalog.
What is the price of the 1 mg presentation?
The published reference price is US$427. This is the value in force at the time of this writing; the page's commercial block always shows the current value.
Who issues Follistatin's certificate of analysis?
Janoshik Analytical, per lot, with purity reported by HPLC and identity confirmed by mass spectrometry (MS). It is handled on request and subject to documentary availability.
How is this reference stored?
According to the documentation applicable to the lot. If it specifies 2–8 °C and protection from light, those conditions are built into the custody record before shipping.
How much does shipping cost?
Rates for Bogotá and for the rest of the country are shown on the site's shipping information. Time is confirmed at the time of quote. 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.
How does Follistatin differ from ACE-031?
Follistatin is a glycoprotein that binds to activin; ACE-031 is a fusion protein that reproduces the activin receptor type IIB with an Fc fragment. They are the two non-short-peptide references in the GH/IGF-1 axis; the comparison is limited to their structural classification.
