Science Library
MacDaddy Peptides Research Centre
Science Library
Clear, evidence-aware guides to emerging research in sports science, metabolism, recovery biology and longevity. Our goal is to help curious readers understand what laboratory and clinical studies show, what remains uncertain and how to evaluate new findings responsibly.
Where to start
New to reading research? Start with how to distinguish preclinical studies from human evidence. For help evaluating laboratory documentation, read how to read a certificate of analysis. Then explore the articles and compound mechanism guides below.
Explore the science
Sports Science & Recovery
Research on training adaptation, connective-tissue biology, recovery pathways and the changing evidence landscape for active adults.
Mitochondria & Metabolism
How cells produce energy, respond to exercise stress and regulate metabolic signalling across the lifespan.
Longevity Science
Research into healthy aging, muscle preservation, cellular stress, inflammation and age-related changes in performance capacity.
Research Evidence Explained
Practical guidance for distinguishing cell studies, animal models, observational research and controlled human trials.
Laboratory Quality
How to read certificates of analysis, understand identity and purity testing and evaluate research-material documentation.
Canadian Research & Regulation
Plain-language discussion of the Canadian research environment, responsible sourcing and relevant regulatory considerations.
Research articles
- Why Recovery Capacity Changes After 35: The Sports-Science View — What the evidence says about muscle, tendon adaptation, training status and recovery across midlife.
- Mitochondria and Athletic Performance: What Changes With Age? — What the evidence says about cellular energy, exercise capacity and the surprisingly important role of training status.
- Muscle Preservation After 45: What Longevity Science Is Studying — What the evidence says about anabolic resistance, resistance training and protein intake.
- Preclinical Versus Human Evidence: How to Read a Peptide Study — How to tell cell, animal and human research apart, and what each can and can’t tell you.
- How to Read a Certificate of Analysis — Identity vs. purity testing, reference standards, lab accreditation, and what a COA does and doesn’t prove.
- Sports Research and Anti-Doping: The Canadian Context — How Canada’s anti-doping framework and Health Canada’s drug rules each treat peptides, and why they’re different questions.
- GHK-Cu Research Overview: What the Science Actually Shows — What the published research shows about GHK-Cu’s role in tissue remodelling, hair follicle biology, antioxidant properties and the limits of current evidence.
- Tesofensine Research Overview: What the Science Actually Shows — The TIPO-1 trial findings, mechanism of action as a triple monoamine reuptake inhibitor, and what the research does not yet establish.
Compound Mechanisms
Detailed mechanism overviews for the specific research compounds carried by MacDaddy Peptides — distinguishing measured laboratory findings from proposed explanations.

- How Tesofensine Works — Dopamine, norepinephrine and serotonin reuptake: the triple mechanism and what animal and human studies show.
- How 5-Amino-1-MQ Works — NNMT inhibition, NAD⁺ metabolism and what the cell and mouse research measured.
- How DADA Works — PDK4 inhibition, the mitochondrial energy gateway and the proposed mechanism behind this research compound.
Our evidence standard
Science Library articles identify the type and strength of evidence, link to original research where available and distinguish established findings from hypotheses. Content is educational and does not provide medical advice, diagnosis, treatment, dosing or human-use instructions.
