The gut–brain axis is a two-way communication system between the digestive tract and the central nervous system, based on hormonal and neural signals. Its central
Blog
The number of PubMed publications on synthetic peptides grows by several to more than ten percent each year. BPC-157 pentadecapeptide, Thymosin Beta-4 fragments, GLP-1 receptor agonists, and nootropic peptides from the Russian pharmacology school ? each of these directions has its own literature, research models, and methodological limitations. This blog organizes that knowledge by category.
Who is this blog for? For people evaluating peptides through analysis of available literature. For academic researchers, biohackers, lifestyle medicine physicians, and pharmacists looking for references to support patient discussions.
Leptin and ghrelin are two hormones with opposing effects on appetite. Leptin, secreted by adipose tissue, is a long-term satiety signal — it informs the
Insulin is an anabolic hormone that regulates energy balance — it lowers blood glucose and promotes energy storage, including in adipose tissue. Insulin resistance is
Metabolic adaptation is the reduction in energy expenditure during and after an energy deficit — greater than would follow from the loss of body mass
The body weight set point is a concept describing body weight as a homeostatically regulated parameter — defended by the body much like temperature or
Triple agonism is a pharmacological strategy based on the simultaneous stimulation of three hormone receptors that regulate metabolism: GLP-1, GIP and glucagon. Rather than acting
Thermogenesis is the production of heat by the body as a result of metabolic reactions. A particular form of it is mitochondrial uncoupling — a
Metabolism is the sum of all the chemical reactions through which the body obtains energy from nutrients and uses it to sustain life: the work
Orforglipron (LY3502970, brand Foundayo) is an oral, small-molecule GLP-1 receptor agonist developed by Eli Lilly and approved by the FDA in 2026. Unlike the peptide
Kisspeptin is a neuropeptide encoded by the KISS1 gene, an agonist of the KISS1R receptor (formerly GPR54), acting as the master regulator of the hypothalamic–pituitary–gonadal
Most peptides in the GH–IGF1 axis cluster act indirectly — secretagogues such as CJC-1295 or Ipamorelin stimulate the pituitary to release growth hormone, which only
Among the synthetic growth-hormone-releasing peptides, Ipamorelin holds a special place — it is a molecule that pharmacological literature often describes with the adjective “clean”. Ipamorelin
GHRP-2 and GHRP-6 are the two peptides most often set side by side from the growth hormone-releasing peptide family — compounds that, in research models,
In the research-reagent trade, the name “CJC-1295” covers two distinct variants of the same peptide — differing by a single chemical modification that changes the
Regulatory note — a critical distinction in the status of the two peptides Tirzepatide functions as a registered medicinal product (Mounjaro — T2D, FDA and
The anti-obesity pharmacology of the past decade has revolved around a design question: what should be added to GLP-1 agonism to achieve an additive or
Discussions of novel pharmacological targets in obesity and metabolic syndrome are today dominated by incretins — semaglutide, tirzepatide, retatrutide — all acting on the GLP-1
In October 2024 the journal Nature Metabolism published a paper that triggered a wave of headlines about an “exercise pill”. Burris’s team at Saint Louis
Mixing peptides with bacteriostatic water means reconstituting a freeze-dried (lyophilized) research peptide by adding a measured volume of bacteriostatic water to the vial, letting the
You do not have to refrigerate unopened bacteriostatic water — sealed vials are stable at controlled room temperature. Once the closure is first punctured, the
Six Knowledge Areas
Regenerative peptides and neuropeptides: molecular mechanisms
The broadest section of the catalog. It covers tissue-regeneration peptides (BPC-157, TB-500, GHK-Cu, PEG-MGF), neuropeptides (Semax, Selank, DSIP), and melanocortin peptides (PT-141, Melanotan II). Each article starts with the discovery context and then moves to the molecular mechanism: signaling pathways, target receptors, and pharmacokinetics.
SARMs ? selective androgen receptor modulators
A class of non-peptide compounds with high affinity for the androgen receptor, intensively studied in the context of anabolic clinical protocols. This section discusses pharmacological mechanisms, phase I and phase II clinical data, and comparisons of research profiles across individual compounds.
Laboratory practice ? reconstitution, storage, analysis
A procedural section. It explains how to correctly reconstitute a lyophilized reagent, which water to use, how to maintain solution stability in the cold chain, and how to interpret the analytical document attached to each batch. Materials for people running laboratory protocols.
Metabolism and incretins ? GLP-1 peptides
A section focused on one of the fastest-growing pharmacological classes of the 21st century: GLP-1 receptor agonists and their derivatives. It covers semaglutide (first generation, well established in clinical trials) and retatrutide (a GLP-1/GIP/glucagon tri-agonist, currently in phase III clinical trials).
Anti-aging and longevity ? peptides in aging research
The fifth area: peptides in the context of cellular aging processes, telomere regulation, neuroplasticity in later adulthood, and social-axis hormones (oxytocin). This section maintains methodological rigor ? highlighting that most evidence still comes from animal models or short-term human trials.
Quality, safety, and regulation
An analytical and regulatory section. It explains how HPLC and MS methods work, which standards apply to research-peptide suppliers in Europe, what to look for when evaluating a source, and what legal status research peptides have in the Polish regulatory system.
