If you're using anabolic steroids, peptides, or other performance-enhancing compounds, the most important tool you have isn't a coach, a forum, or a Reddit thread. It's regular, comprehensive bloodwork.
This guide is written for adult men in New Zealand who are already enhanced, are considering it, or are coming off a cycle and want to know what's happening internally. It's harm-reduction, not endorsement — the safest path is not to use these compounds at all. But pretending men aren't using them doesn't help anyone, and quality information from a registered NZ doctor beats whatever you find at 1am on r/steroids.
Why this matters
Enhanced athletes face a specific set of physiological risks that standard GP bloodwork doesn't catch. A regular health screen tests roughly 10–15 markers. A proper enhanced-athlete panel tests 25–35, including some that aren't routinely available unless you ask specifically.
Without monitoring, the things that actually kill enhanced athletes — cardiovascular disease, polycythaemia, acute kidney injury, untreated sleep apnoea — develop silently for years. With monitoring, almost all of them are catchable and reversible.
The four phases of a cycle and what to test in each
Phase 1 — Pre-cycle baseline (4–6 weeks before starting)
Establish where you stand naturally so future results have something to compare to. Without a baseline, all your post-cycle bloods are meaningless.
Minimum panel:
- Full blood count (especially haematocrit, haemoglobin, platelets)
- Comprehensive metabolic panel (electrolytes, liver enzymes, kidney function)
- Lipid panel (total, LDL, HDL, triglycerides)
- Total testosterone, free testosterone, SHBG
- LH, FSH
- Estradiol (sensitive assay)
- Prolactin
- DHEA-S
- HbA1c, fasting glucose, fasting insulin
- TSH, free T4
- Iron studies + ferritin
- PSA (in men over 35 or with risk factors)
- Vitamin D, B12, folate
- High-sensitivity CRP
- Apolipoprotein B (better predictor of cardiovascular risk than LDL alone)
- Resting ECG and a discussion of family cardiac history
Phase 2 — Mid-cycle (6–8 weeks into a cycle)
You're now seeing what your protocol is actually doing. The non-negotiables here:
- Haematocrit — anabolic steroids increase red cell production. Above 54% materially raises stroke risk. This is the single most common cause of enhanced-athlete hospitalisations.
- Lipids — particularly oral compounds tank HDL and elevate LDL. ApoB tells the truth.
- Liver function — 17α-alkylated orals (oxandrolone, methyltestosterone, etc.) stress the liver. Even injectable AAS show some hepatic strain.
- Kidney function — creatinine rises mechanically with muscle mass; cystatin C is a better marker for kidney function in muscular men.
- Estradiol — high (gyno, water retention, mood) and very low (joint pain, low libido, lipid worsening) are both problems.
- Blood pressure — measure at home, weekly, on a validated cuff. Cardiovascular events in enhanced athletes correlate more tightly with sustained hypertension than with any single biomarker.
Phase 3 — End of cycle / post-cycle therapy
You're now stress-testing the HPTA (hypothalamic-pituitary-testicular axis) and watching it recover.
- LH, FSH, total and free testosterone — recovery trajectory
- Estradiol — to monitor if SERMs are being used
- Prolactin — particularly if 19-nor compounds were used
- Liver enzymes — for clearance of orals
- Lipids — recovery of HDL takes longer than people think
- Mental health — the post-cycle crash is real. If mood symptoms persist past 6 weeks, get help.
Phase 4 — Off-cycle / cruise / TRT decision point
Three months off, retest the full baseline panel. The key question: has your natural production come back, and is everything else back to normal?
If natural testosterone hasn't recovered after 6 months, you have decisions to make. Sometimes that decision is medically supervised TRT. Either way, this is a conversation to have with a doctor who isn't going to lecture you out of the room.
Getting these bloods done in NZ
Most of the markers above are available through standard NZ community labs (Awanui / Pathlab / Medlab depending on region) on a doctor's request form. A few — fasting insulin, ApoB, sensitive estradiol, cystatin C — sometimes need a private path, but they're usually requestable.
You will need a NZ-registered doctor to request them. Self-ordering of laboratory tests in NZ is limited and the comprehensive panels above aren't available DTC (direct-to-consumer) in most parts of the country.
A clinic willing to work with enhanced athletes will:
- Take a full and honest history without judgement
- Order the comprehensive panel above (not just testosterone)
- Discuss your specific compounds, doses and goals
- Provide ongoing monitoring at appropriate intervals
- Refer onward (cardiology, hepatology, mental health) when indicated
What an enhanced-athlete clinic should NOT do
- ❌ Prescribe AAS or SARMs for performance purposes (against Medical Council of NZ standards)
- ❌ Source compounds for you
- ❌ Encourage cycles or higher doses
- ❌ Charge for tests that aren't clinically indicated
What a good clinic will do is: monitor you while you make your own informed choices, treat actual hypogonadism with TRT where appropriate, manage side effects of compounds you've already taken, and make sure you don't end up in the cardiology ward at 38.
A note on the law
In New Zealand, anabolic steroids are Class C controlled drugs under the Misuse of Drugs Act 1975. Importing or possessing them without a prescription is illegal. A doctor cannot prescribe them for performance enhancement. A doctor can:
- Diagnose and treat hypogonadism (including hypogonadism caused by previous AAS use)
- Manage health markers in a patient who is using these compounds
- Prescribe within their normal scope (TRT, ancillary medications) according to legitimate clinical indication
Be honest with whoever you see. Doctors who know what's actually going on can keep you safe. Doctors who are kept in the dark can't.

FAQ
Will my GP write me an enhanced-athlete blood panel? Some will, some won't. Many GPs feel out of their depth or don't know what to test. Specialist men's-health clinics fill this gap.
Is it legal for a NZ doctor to monitor me if I'm using AAS? Yes. Doctors can manage health markers in patients regardless of those patients' lifestyle choices. They cannot prescribe AAS for performance.
How often should I test? Pre-cycle, mid-cycle (every 6–8 weeks while on), end-of-cycle, and 3 months post-cycle. Plus 6-monthly cardiovascular and metabolic re-checks if you cycle frequently.
What's the single most important number to watch? Haematocrit. Stroke risk goes up steeply above 54%. It's also the most easily managed (therapeutic phlebotomy / blood donation works).
Can I get TRT through Enhanced Men if my natural testosterone hasn't recovered after AAS use? If clinical criteria for hypogonadism are met after appropriate work-up — yes. The pathway is the same as any other TRT patient. See our TRT guide.
