About Peptidegenics

What this site is

Peptidegenics is a reference publication covering the intersection of peptide biochemistry, nutrition science, and metabolic physiology. It is not a supplement review site, a product retailer, or a medical advice service. It is a data-forward publication written for people who already understand macronutrient partitioning, track their training loads, and want mechanistic explanations grounded in primary literature.

Every article addresses a specific metabolic question. The answer reflects what published research shows — not what the peptide community believes, what is convenient to claim, or what a hypothetical mechanism suggests. Where evidence is animal-only, that is stated. Where dosing is extrapolated, that is stated. Where no human data exists for a specific dietary context, that is stated precisely: "No human dose-ranging data on this application has been published as of the available literature."

The Metabolic Applicability Rating

Every article on Peptidegenics carries a Metabolic Applicability Rating — a trust signal unique to this publication. It classifies how directly the evidence in a given article translates to real dietary and training contexts. The five levels are:

• Directly Applicable — Human studies with dietary or training context specified. Dose, timing, and nutritional state are defined.
• Context-Dependent — Evidence exists but key variables (fasting state, macronutrient composition, training volume) were not controlled or reported.
• Extrapolated — Animal or in vitro data directionally relevant to metabolic questions but requiring extrapolation to human dietary contexts.
• Mechanistic Only — Cellular or molecular mechanism data with no dietary or performance context.
• Conflicting Data — Multiple studies with contradictory results in metabolic context. The article synthesises the conflict rather than resolving it.

This classification answers the question the performance-focused reader actually asks: does this evidence apply to how I actually eat and train? A study with strong evidence (RCT design, large sample) can still be rated Context-Dependent if the researchers only examined fed-state conditions and the reader trains fasted. The rating enforces editorial honesty and gives readers the information they need to assess relevance to their own situation.

Editorial standards

Numbers are used wherever they exist. Specific values — percentage changes in IGF-1, kilograms of lean mass gained, study duration and protocol details — are stated directly with citations. Vague descriptions ("significantly higher", "substantial improvement") are replaced with the actual figures when the study reports them. Where numbers do not exist, the absence is named: the article does not substitute an impression for a measurement.

Primary sources take precedence over secondary commentary. Fitness forums, podcasts, and influencer summaries are not evidence. The study itself is the evidence. Citations link to original research — PubMed, JISSN, JCEM, AJP, NSCA publications — wherever possible.

Uncertainty is acknowledged explicitly. "Preliminary" means findings exist but have not been tested in controlled human trials. "Animal only" means the sole evidence comes from rodent or in vitro models. These distinctions are preserved in every article and never softened into vagueness.

No commercial interest

This site sells nothing. There are no affiliate links to peptide suppliers, compounding pharmacies, supplement retailers, or any other commercial entity. There is no advertising. No content is sponsored. No payment influences editorial decisions in any direction.

Peptidegenics exists because the peptide and sports science space has a significant information quality problem: mechanistic speculation is presented as applied evidence, animal studies are extrapolated to human protocols without acknowledgment, and commercial interests systematically bias the framing of research. An independent publication applying consistent editorial standards to metabolic translational relevance is a direct response to that problem.

What this site is not

This site does not provide medical advice and is not a substitute for clinical consultation. It is sports science and nutrition analysis content — not health or clinical guidance. The research presented here is descriptive. It describes what studies found in specific dietary and training contexts. It does not prescribe protocols, recommend specific peptides for individual use, or advise on sourcing.
