What is the Longevity Peptide Baseline Profile?

The Longevity Peptide Baseline Profile is a comprehensive blood test designed to establish a clinical baseline before initiating peptide, GH, or regenerative protocols. It evaluates core organ function, metabolic health, inflammation, nutritional status, and—critically—the hormone and growth factor axis that peptides interact with.

This profile ensures peptides are used safely, effectively, and intelligently, reducing risk while maximising therapeutic benefit. It is suitable for individuals planning longevity optimisation, body recomposition, recovery protocols, or anti-ageing interventions.

Why do I need a Longevity Peptide Baseline Profile?

Peptides do not work in isolation. Their effects depend heavily on liver function, insulin sensitivity, thyroid activity, sex hormones, IGF-1 signalling, and inflammatory status. Starting peptides without a baseline increases the risk of poor response, side effects, or missed contraindications.

This test is recommended if you are:

• Planning GH, IGF-modulating, or repair peptides
• Optimising longevity or anti-ageing strategies
• Focused on recovery, muscle repair, or metabolic health
• Managing fatigue, inflammation, or slow recovery
• Interested in safe hormone optimisation
• Tracking biological age and healthspan

Common symptoms that justify baseline testing include:

• Low energy or poor recovery
• Fat gain despite training
• Poor sleep or stress tolerance
• Reduced muscle response
• Hormonal imbalance symptoms
• Chronic low-grade inflammation

What does the profile include?

Core health & safety markers

Full Blood Count (5-part differential)
Assesses immune health, oxygen delivery, and systemic stress.

Liver Function
ALT, AST, ALP, GGT, Bilirubin, Albumin – ensures safe peptide metabolism.

Kidney Function
Creatinine, eGFR, Urea – critical for clearance and dosing safety.

Metabolic control

Glucose regulation
Fasting Glucose, HbA1c, Fasting Insulin – identifies insulin resistance before GH-axis manipulation.

Lipid profile
Total Cholesterol, HDL, LDL, Triglycerides – cardiovascular and metabolic risk assessment.

Inflammation

hs-CRP
Detects low-grade inflammation that can blunt peptide response.

Thyroid function

TSH, Free T4, Free T3 – thyroid optimisation is essential for metabolic and peptide effectiveness.

Iron & repair capacity

Iron, Ferritin, TIBC, Transferrin Saturation – oxygen delivery and mitochondrial support.

Vitamins & minerals for repair

Vitamin D, Vitamin B12, Folate, Magnesium, Zinc – essential for tissue repair, immunity, and hormone synthesis.

Hormone axis (critical before peptides)

Total Testosterone
Sex Hormone Binding Globulin (SHBG)
Free Testosterone (calculated)
Estradiol
DHEA-S

These markers ensure hormonal balance before introducing peptides that may amplify endocrine signalling.

Growth & repair signalling

IGF-1
Essential baseline before any GH-related or regenerative peptide protocol.

Pancreatic support

Amylase
Assesses pancreatic enzyme activity and digestive health.

Benefits of the test

1. Establishes a safe peptide baseline

2. Reduces risk before GH or repair peptides

3. Optimises hormone environment

4. Identifies insulin resistance early

5. Detects hidden inflammation

6. Supports personalised longevity planning

7. Improves peptide response predictability

8. Provides measurable starting point for tracking progress

Expanded benefit explanation
This profile ensures that longevity and peptide protocols are built on a stable physiological foundation, allowing smarter dosing, better outcomes, and safer long-term optimisation.

Both services are available UK-wide.

Your results explained

Sub-optimal / low markers

May indicate nutrient deficiencies, hormonal suppression, insulin resistance, or impaired repair capacity that should be addressed before peptides.

Optimal ranges

Indicate readiness for longevity, recovery, or regenerative protocols.

Elevated markers

May suggest inflammation, metabolic stress, hormonal imbalance, or safety concerns requiring optimisation or medical review.

UK laboratory reference ranges are provided with all results for clinical clarity.
