## What does the Peptide Therapy Monitoring Panel cover?

53 biomarkers for peptide therapy patients — covers metabolic, hormonal, thyroid, cardiovascular, inflammation, and growth factor markers in a single draw, including SHBG for accurate Free + Total Testosterone interpretation.

The Standardized Peptide Panel is designed for patients undergoing peptide therapy (BPC-157, GHK-Cu, Thymosin, CJC/Ipamorelin, and others). It combines 53 biomarkers across 19 targeted tests that clinicians use to monitor peptide therapy efficacy and safety. IGF-1 tracks growth hormone axis response — the primary marker for GH-releasing peptides. A full thyroid panel (TSH, Free T3, Free T4) catches thyroid shifts. Testosterone (Free & Total) plus SHBG together give the true bioavailable testosterone picture (Total alone is misleading without knowing how much is bound). Estradiol, DHEA-S, and Cortisol assess the rest of the hormonal landscape. CMP, CBC, and a Lipid Panel monitor metabolic and organ health. HbA1c and Insulin evaluate glucose metabolism, which peptides like CJC-1295 can influence. hs-CRP tracks systemic inflammation. Ferritin, Iron, and Vitamin B12 ensure nutrient status supports therapy. Vitamin D rounds out the picture as a co-factor for immune and hormonal function. Recommended at baseline, 4–6 weeks into therapy, then quarterly.

**Clinical use:** Baseline and periodic monitoring for peptide therapy — GH-releasing peptides (CJC-1295, ipamorelin, sermorelin, MK-677), BPC-157, and multi-peptide stacks. IGF-1 tracks the growth-hormone axis (the primary efficacy marker for GH peptides); a full thyroid panel, Testosterone with SHBG, estradiol, DHEA-S, and cortisol map the hormonal landscape; CMP, CBC, lipids, A1c, and fasting insulin cover organ and metabolic safety; hs-CRP tracks inflammation. Measures the body's response to a protocol — not the contents of a peptide vial.

## Who should order it?

Anyone on or starting peptide therapy who wants objective safety and efficacy data — especially GH-peptide users tracking IGF-1, people establishing a pre-protocol baseline, and those sourcing peptides without clinical oversight for whom independent monitoring is the only safety net. Not a substitute for a prescriber; abnormal results are a prompt to involve a clinician.

## How much does a Peptide Therapy Monitoring Panel cost?

A Peptide Therapy Monitoring Panel costs $259.99 at TestWell — $265.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. With insurance, what you pay depends on your deductible and your plan's negotiated rate; TestWell's price is fixed before the draw and is HSA/FSA-eligible.

| Where you order | Price | One test, all-in | Notes |
| --- | --- | --- | --- |
| TestWell (drawn at Quest or Labcorp) | $259.99 | $265.99 | Includes the one $6 lab processing fee, charged once per order |

## How do you prepare?

Fasting for 10–12 hours is required. Morning blood draw (before 10 AM) is preferred for accurate cortisol and hormone levels. Water is okay. If on injectable peptides, draw blood at trough (before next dose) for most accurate baseline.

## Is the Peptide Therapy Monitoring Panel worth it?

> Worth it if you're on peptide therapy — GH-releasing peptides (CJC-1295, ipamorelin, sermorelin, MK-677), BPC-157, or a multi-peptide stack — and want objective proof it's safe and working. It bundles the 53 biomarkers peptide users actually track, including IGF-1 (the key efficacy marker for GH peptides) and SHBG for accurate free-testosterone reading, into one draw at roughly half the à la carte cost. It monitors YOUR body's response — it does not test the peptide vial's contents.

### Worth it if you…

- Anyone on GH-releasing peptides who wants to see their IGF-1 actually move — the single best signal the protocol is doing something
- Peptide users who want a proper baseline before starting, so later results mean something
- Multi-peptide or hormone-stacking protocols where one draw covering IGF-1, thyroid, testosterone + SHBG, metabolic, and inflammation beats ordering ten tests piecemeal
- People sourcing peptides without clinical oversight, for whom independent monitoring is the only safety net

### You can probably wait if you…

- You want to verify a vial's purity or contents — that's a chemical assay from a substance-testing lab, not a blood test
- You're only on a GLP-1 for weight loss — the [GLP-1 Monitoring panel](https://www.test-well.com/tests/glp1-monitoring-panel) is purpose-built and cheaper for that
- You just want to track one marker between full panels — [IGF-1](https://www.test-well.com/tests/igf-1-test) alone is far cheaper for GH-peptide follow-ups

### At home or in the lab?

At-home collection is available. A fasting morning draw (10-12 hours, water okay) at Quest or Labcorp, or at-home phlebotomy where available. If you're on injectable peptides, draw at trough — right before your next dose — for a consistent, comparable baseline. Cortisol and hormones read most accurately before 10 AM.

### How do you read the results?

| Result | Typical adult range | What an out-of-range value can mean |
| --- | --- | --- |
| IGF-1 | Age/sex-specific range | The primary efficacy marker for GH-releasing peptides — the stable downstream signal of growth-hormone activity. If it isn't rising on a GH peptide, the protocol (or the product) isn't doing much. Very high levels warrant a clinician conversation. |
| Fasting glucose + insulin + HbA1c | Glucose 70-99 mg/dL; A1c <5.7% | GH-axis stimulation can raise blood sugar and insulin over time. Watching these catches a drift toward insulin resistance early, while it's easy to address. |
| Testosterone (Free & Total) + SHBG | Sex-specific ranges | Total testosterone alone is misleading without SHBG, which determines how much is bioavailable. Together they give the true free-testosterone picture peptide and hormone users need. |
| CMP + CBC + hs-CRP | Within lab reference ranges | The safety backbone: liver and kidney function, blood counts, and systemic inflammation. Any drift here is the signal to pause and get evaluated rather than push through. |

## Common questions about the Peptide Therapy Monitoring Panel

### Does the peptide panel test the peptide itself or my body?

Your body's response — IGF-1, hormones, metabolic and organ markers. It cannot verify the identity, purity, or concentration of what's in a vial; that's a chemical assay (mass spec / HPLC) from a substance-testing lab, not a medical blood test. See the [peptide therapy bloodwork guide](https://www.test-well.com/guides/peptide-therapy-bloodwork) for the full distinction.

### Which peptides is this panel for?

It's built for GH-releasing peptides (CJC-1295, ipamorelin, sermorelin, MK-677), BPC-157 and repair peptides, and hormone-adjacent stacks. IGF-1 is the standout efficacy marker for the GH group. If you're only on a GLP-1 for weight loss, the [GLP-1 Monitoring panel](https://www.test-well.com/tests/glp1-monitoring-panel) is purpose-built and cheaper — see the [GLP-1 lab monitoring guide](https://www.test-well.com/guides/glp1-lab-monitoring).

### When should I draw blood relative to my peptide dose?

For injectable peptides, draw at trough — right before your next scheduled dose — so results are comparable over time. Fast 10-12 hours (water is fine) and aim for a morning draw before 10 AM for accurate cortisol and hormone levels. A baseline before you start is the single most valuable draw.

### Are peptides like BPC-157 safe, and can bloodwork tell me?

Many research peptides, including BPC-157, are not FDA-approved for general human use and have limited human safety data — so no one can promise they're safe for you. Bloodwork can't change that, but it's the practical harm-reduction tool: baseline and periodic organ, blood, and inflammation markers catch problems early. There's no test that measures BPC-157 itself — see the [BPC-157 bloodwork guide](https://www.test-well.com/guides/bpc-157-safety-bloodwork).

### How often should I retest on peptide therapy?

The standard cadence is baseline (before starting), a follow-up at 4-6 weeks, then quarterly for as long as you're on the protocol. Because peptide therapy is ongoing, monitoring is ongoing — many users set up a recurring quarterly plan so the retest happens automatically rather than being remembered.

### How much does the peptide panel cost without insurance?

$259.99 at Quest for all 53 biomarkers (19 tests) — roughly half the ~$500 Quest Direct charges for the equivalent. HSA/FSA eligible, no doctor's visit or referral needed.

### Does this panel test the peptide itself or my body?

Your body. It measures how your physiology is responding to a peptide — IGF-1, hormones, metabolic and organ markers. It cannot verify the identity, purity, or concentration of what's in a vial; that's analytical chemistry from a substance-testing lab, not a medical blood test.

### When should I draw blood relative to my dose?

For injectable peptides, draw at trough — right before your next scheduled dose — so every draw is comparable over time. Fast 10-12 hours (water is fine) and aim for a morning draw before 10 AM for accurate cortisol and hormone levels.

### How is this different from the GLP-1 Monitoring panel?

The Peptide Therapy Monitoring Panel is built for GH-releasing peptides, BPC-157, and hormone-adjacent stacks — it leads with IGF-1 and a full hormone workup. The [GLP-1 Monitoring panel](https://www.test-well.com/tests/glp1-monitoring-panel) is purpose-built for semaglutide/tirzepatide weight-loss therapy and is cheaper if that's all you're on. Choose by what you're actually taking.

### Do I need this if I buy peptides without a prescription?

TestWell takes no position on how you obtain peptides, and many research peptides aren't FDA-approved for general human use. What's true regardless: the less clinical oversight your source comes with, the more valuable independent monitoring is — baseline and quarterly bloodwork is how you catch a problem before it's serious. Every result is physician-reviewed.
