GF1-LR3 stands as a modified variant of insulin-like
growth factor-1, known by its complete designation as
insulin-like growth factor-1 long arginine 3. All derivatives
of IGF-1 significantly contribute to cellular division,
proliferation, and intercellular communication. Despite
sharing similar effects, IGF-1 LR3 exhibits a weaker binding
affinity to IGF binding proteins in comparison to IGF-1.
Consequently, IGF1-LR3 remains in circulation around 120
times longer than IGF-1. This prolonged half-life of IGF1-
LR3 stems from structural modifications; the peptide’s
formulation involves the addition of 13 amino acids to the
N-terminal end of IGF-1 and the transformation of glutamic
acid at position 3 of IGF-1 into an arginine residue.

PT-141, known as bremelanotide, has earned the
nickname “female Viagra” due to its past exploration in
phase IIb human clinical trials for managing female
hypoactive sexual desire disorder (HSDD). This peptide,
categorized as a melanocortin, primarily targets the
melanocortin 4 receptor (MC-4R) and MC-1R. Additionally,
in 2009, investigations into PT-141 extended to its
potential application in addressing acute hemorrhage.
Derived from another synthetic melanocortin, melanotan 2
(MT-2), PT-141 has garnered attention for its multifaceted
research applications beyond its initial link to sexual desire
disorder in women.

Selank, originating from Russia, stands as a brief peptide
possessing both nootropic and anxiolytic attributes.
Serving as a synthetic counterpart to the naturally existing
Tuftsin, an immunomodulatory peptide, Selank mirrors
Tuftsin closely, differing mainly by containing an additional
four amino acids in its chain. This modification aids in
enhancing its metabolic stability and extending its half-life.
Notably, Selank, like Tuftsin, influences IL-6, T helper cells,
monoamine neurotransmitters, and brain-derived
neurotrophic factor (BDNF). The fundamental similarities
between Selank and Tuftsin lie in their structure, with
Selank’s slight alteration in amino acids contributing to
improved stability and longevity.
Clinical trials have explored Selank’s potential application
as a treatment for generalized anxiety disorder.
