Our reference catalog is organized around the established research fields of peptide science. Each field links into the filtered study journal and the matching compound catalog.
Incretin and metabolic signaling (GLP-1, GIP, glucagon) — among the most active clinical research areas.
Tissue repair, angiogenesis and regeneration — predominantly preclinical models.
Neuromodulation, cognition and sleep-wake regulation in the CNS.
Cellular senescence, telomere biology and geroprotective peptides.
Skin matrix, collagen signaling and topical formulation research.
Growth-hormone axis and sports-related endocrine research.
Immunomodulation and antimicrobial peptides.
Pharmacological characterization and translational drug research.
This overview places the catalog's compound classes at the level of their known molecular targets — textbook-level and general. It is scientific context for research (RUO), not a product or health claim.
Analogs of incretin hormones bind the G-protein-coupled receptors GLP-1R, GIPR and the glucagon receptor. Research characterizes receptor binding, signal transduction and receptor selectivity of this compound class.
GHRH analogs and selective secretagogues address the hypothalamic-pituitary axis. Studied properties include receptor affinity, secretory pulsatility and half-life-modifying conjugations.
Peptides in this class are examined in preclinical models in the context of angiogenesis, cell migration and actin dynamics. The evidence is predominantly in-vitro and animal.
Mitochondria-derived or -targeting peptides are researched for cardiolipin interaction, electron transport and metabolic homeostasis.
α-MSH analogs and fragments interact with melanocortin receptors (MC1R–MC5R). Research contexts range from photoprotection to inflammation-modulating fragments.
ACTH fragments, tuftsin analogs and sleep-associated peptides are studied in the context of neuroplasticity, neurotransmitter balance and sleep architecture.
Senolytic and regulatory peptides are researched in relation to cellular aging, apoptosis of senescent cells and telomere biology — largely preclinical to date.

The referenced works describe the respective compound class in scientific or clinical research contexts. They are not statements about goodaminos products and do not establish any medical benefit. For research use only (RUO).

Core concepts from peptide chemistry, analytics and study methodology.
The works listed in the journal are drawn from publicly available, peer-reviewed literature. Where a DOI exists, the entry links directly to the original source for independent review.
Not all evidence is equal: in-vitro and animal models provide mechanistic hints, while randomized controlled human trials carry the strongest weight. Each study card states its type, model and, where applicable, participant count.
References describe the compound class in a research context — they are explicitly not efficacy or health claims about our products. All materials are Research Use Only (RUO).
Cell culture / molecular assays — mechanistic hints.
Preclinical in-vivo data.
Randomized, controlled — strongest single-study evidence.
Synthesis of multiple RCTs — strongest overall statement.
The most common questions about research peptides, analytics and interpretation.
Synthetically produced peptides used as reference and investigational material in laboratory and in-vitro research. They are not intended for human use.
RUO is the regulatory framework for materials supplied strictly for research. No therapeutic claims are made and no medical application is recommended.
The share of the target compound in the total substance, determined by RP-HPLC. Higher purity reduces side peaks and improves experimental reproducibility.
No. The studies describe the respective compound class in scientific research contexts. They are not evidence of a benefit of the reference materials we offer.
