What is the Longevity Peptide Monitoring Profile?

The Longevity Peptide Monitoring Profile is a targeted follow-up blood test performed 8–12 weeks after starting peptide, GH-related, or repair protocols. It focuses on the most sensitive markers that reflect response, safety, and overstimulation risk, rather than repeating a full baseline.

This profile allows fine-tuning of protocols, early detection of adverse trends, and evidence-based continuation or adjustment of therapy.

Why do I need a monitoring profile?

Peptide therapy can shift glucose control, IGF-1 signalling, thyroid metabolism, and sex hormone balance within weeks. Without monitoring, subtle but important changes may be missed.

This test is recommended if you are:

• 8–12 weeks into peptide or GH-axis therapy
• Using growth, recovery, or longevity peptides
• Optimising body composition or metabolic health
• Monitoring safety during hormone-sensitive protocols
• Adjusting peptide dose or cycling strategy

Common reasons for monitoring include:

• Ensuring IGF-1 is not overstimulated
• Detecting early insulin resistance
• Monitoring liver and kidney tolerance
• Tracking hormone shifts
• Optimising long-term outcomes

What does the profile include?

Liver function (sensitivity markers)

ALT, AST, GGT (most sensitive)
Detects early liver stress or metabolic overload.

Kidney function

Creatinine, eGFR
Ensures safe clearance and renal tolerance.

Glucose control

Fasting Glucose
Fasting Insulin
HbA1c
Identifies insulin resistance or metabolic drift during therapy.

Lipids

HDL, LDL, Triglycerides
Monitors cardiovascular and metabolic impact.

Inflammation

hs-CRP
Detects low-grade inflammation that may blunt peptide benefits.

Thyroid (metabolic shift)

TSH
Free T3
Assesses metabolic response and thyroid adaptation.

Hormonal balance

Testosterone
Sex Hormone Binding Globulin (SHBG)
Estradiol
DHEA-S
Ensures endocrine balance is maintained during therapy.

Growth signalling

IGF-1
Critical marker to confirm GH axis is stimulated but not overstimulated.

Repair nutrients

Vitamin D
Magnesium
Zinc
Supports tissue repair, immunity, and hormone synthesis.

Benefits of the test

1. Confirms peptide safety at 8–12 weeks

2. Detects IGF-1 overstimulation early

3. Monitors glucose and insulin response

4. Tracks liver and kidney tolerance

5. Identifies metabolic drift

6. Ensures hormone balance is maintained

7. Guides dose or protocol adjustment

8. Supports long-term longevity optimisation

Expanded benefit explanation
This monitoring profile allows peptide protocols to be adjusted proactively, preventing long-term metabolic or hormonal issues while maximising benefit.

Your results explained

Sub-optimal trends

May indicate early insulin resistance, rising inflammation, hormonal imbalance, or excessive GH stimulation requiring protocol adjustment.

Optimal response

Markers remain within range, indicating good tolerance and effective response.

Elevated or suppressed markers

May signal overstimulation, metabolic stress, or nutrient depletion and should be reviewed before continuing or escalating therapy.

UK laboratory reference ranges are included with all results.
