MOLECULE PROFILE

IGF-DES / des(1–3)IGF-I

Protein or biologic

Modified IGF-I signaling/binding properties; exact molecule must be confirmed.

Sources checked · October 16, 2026

Published for review · Scientific, medical, translation and citation review pending. Reported uses are not authorized indications. Frequency reflects mentions in supplied sources, not sales or global clinical prevalence.

Identity and synonyms

Identity follows the supplied name and synonyms; no additional identity description is supplied.

Protein or biologic · Protein or protein analogue

Detailed molecular class: Truncated protein analogue

Supplied sequence or chemical reference

See identity note; no supplier sequence accepted as verification.

Mechanism

Modified IGF-I signaling/binding properties; exact molecule must be confirmed.

Evidence and critical reading

Reported scientific and empirical uses

Reported muscle and performance

Truncated IGF-I sold as an anabolic enhancer; modifications are not trivial.

Human evidence

No controlled human efficacy finding was verified for the exact catalog identity in this screen.

Preclinical evidence

Analytical detection and animal exposure study; not clinical efficacy.

Critical reading and limitations

An antidoping analytical study demonstrates detectability, not therapeutic efficacy or human safety.

Evidence applies to the exact molecule, formulation, route, population and endpoint studied. Supplier identity, purity and clinical equivalence are unverified.

Source-specific regimens

Descriptive source observations, not individual recommendations.

Regulatory product labeling

No numerical human dose is assigned: reviewed sources did not verify a regimen attributable to this material, route and indication. Other molecules’ doses, animal exposures, vial amounts and dietary requirements are not substituted.

Human-study exposure

No numerical human dose is assigned: reviewed sources did not verify a regimen attributable to this material, route and indication. Other molecules’ doses, animal exposures, vial amounts and dietary requirements are not substituted.

Empirical handbook

No numerical human dose is assigned: reviewed sources did not verify a regimen attributable to this material, route and indication. Other molecules’ doses, animal exposures, vial amounts and dietary requirements are not substituted.

Regulation and safety

Jurisdiction-specific regulatory context

Jurisdiction-specific approval not verified in this card; do not infer global nonapproval.

Adverse effects and unknowns

Human safety, contraindications and interactions are not adequately established for the catalog product. Missing reports are not evidence of safety.

No validated human regimen in this dossier; do not infer dosing from LR3 or mecasermin.

Contraindications

See supported safety statements and exact product label; a complete contraindication set has not been established for this catalog material.

A complete list must match the exact authorized product. For experimental materials without verified human labeling, a complete contraindication set is not established here. No list does not mean safety.

Interactions

Only explicitly cited interactions may be asserted; unstudied combinations remain unknown, not interaction-free.

Separate documented interaction, pharmacologic plausibility and unknown interaction. Absence of a blend trial does not establish compatibility.

Studies and trials

Selected studies

No selected studies are attributed in this record.

Trials attributed in the package

No trials are attributed in this record.

Trial registration does not establish efficacy or validate commercial material.
