Post-cycle blood work is your window into recovery. It tells you whether your HPTA is waking up, whether organ stress has resolved, and — most importantly — whether it is safe to start another cycle.
The timing of post-cycle testing matters enormously. Test too early and you will see incomplete recovery and panic unnecessarily. Test too late and you miss the opportunity to intervene if something is going wrong.
Week 4-6: The Recovery Check-In
Four to six weeks after your last injection (and after completing PCT if you are using one), it is time for the first post-cycle blood work. This panel should focus on hormonal recovery:
- Total testosterone (TT) — At this point, exogenous testosterone should be cleared. Any detectable testosterone is endogenous production. A reading of 200-400 ng/dL at week 4-6 is encouraging — it means your HPTA is starting to wake up.
- LH (luteinizing hormone) — This is the most important marker at this stage. LH above 2 mIU/mL signals that your pituitary is sending signals to your testes again. LH below 1 mIU/mL means recovery has not yet begun.
- FSH (follicle-stimulating hormone) — Supports spermatogenesis. Recovery of FSH often lags behind LH by several weeks.
- Estradiol (E2) — Can be low or high during recovery. Low E2 is expected if testosterone is still suppressed. High E2 can occur if LH surges and the testes produce more testosterone than aromatase can handle — this usually resolves on its own.
- SHBG — Should be rising toward your natural baseline. Low SHBG off-cycle is a red flag for metabolic issues.
What if LH is still < 1 at week 6?
If LH is undetectable at week 6, your HPTA is still suppressed. This does not automatically mean PCT failed — some users take longer to recover. Continue monitoring every 2-4 weeks. If LH has not budged by week 10-12, consider extending or repeating PCT under medical guidance.
Week 8-12: The Full Recovery Panel
By week 8 to 12, most users should see significant recovery. This is the time to run a full panel that covers all systems:
- Total and free testosterone — TT should be in your natural range (typically 400-800 ng/dL for most men). Free T should normalize as SHBG returns to baseline.
- LH and FSH — Should be in the normal range (LH 2-8 mIU/mL, FSH 2-10 mIU/mL). This confirms your HPTA is fully active.
- Estradiol (sensitive) — Should be in your natural range. If E2 is persistently low while TT is normal, consider SHBG status and aromatase function.
- Lipid panel — HDL should be recovering toward baseline. If HDL is still < 30 mg/dL (0.8 mmol/L) at week 12, investigate further.
- Liver enzymes (AST, ALT, GGT) — Should be near baseline. Persistent elevation of GGT at week 12 suggests ongoing hepatic stress.
- eGFR and creatinine — Should be back to pre-cycle levels. If eGFR dropped during cycle, it should recover fully within 8-12 weeks.
- CBC (complete blood count) — Hematocrit and hemoglobin should be trending toward baseline. If hematocrit is still above 50% at week 12, investigate for sleep apnea or other causes.
- HbA1c and fasting glucose — Metabolic recovery. Insulin sensitivity should return to baseline after discontinuing androgens.
What to Expect During Recovery
Recovery is rarely a straight line. Here is what normal looks like:
- Temporary low testosterone — Even with successful PCT, it can take 8-16 weeks for testosterone to reach your pre-cycle baseline. Levels of 200-400 ng/dL at week 6 are normal and will continue to rise.
- Low HDL — HDL can remain suppressed for 6-12 weeks after stopping AAS, especially if you used oral compounds. It will recover as your lipid metabolism normalizes. Cardio, omega-3s, and a Mediterranean diet can help speed this up.
- Elevated liver enzymes from orals — If you used oral AAS, AST and ALT may remain elevated for 4-8 weeks after discontinuation. GGT helps distinguish this from ongoing liver damage. If GGT is normal, the elevation is likely benign and resolving.
- Mood fluctuations — Hormonal shifts during recovery can cause mood swings, low energy, and changes in motivation. This is temporary and improves as hormone levels stabilize.
- Libido variability — Libido may be low, high, or unpredictable during recovery. This is normal and reflects the fluctuating hormone levels as your system recalibrates.
When to Worry: Red Flags
While most recovery is uneventful, certain findings warrant medical attention:
- Persistent suppression > 12 weeks — If total testosterone is still below 200 ng/dL and LH is below 1 mIU/mL at week 12, the HPTA has not recovered. This requires endocrinological evaluation.
- HDL still < 30 mg/dL (0.8 mmol/L) at week 12 — This is not normal recovery. Investigate for other causes: genetics, diet, or other medications.
- eGFR decline > 15% from baseline at week 12 — Kidneys should recover fully. Persistent decline suggests possible kidney injury.
- Severe depression or anxiety — While some mood fluctuation is normal, severe or prolonged depression is not. Do not dismiss mental health symptoms as "just recovery."
- Gynecomastia developing during recovery — As E2 fluctuates during recovery, gyno can develop or worsen even if you had no issues on cycle. Monitor and address early if needed.
Do Not Start a New Cycle Before Confirming Recovery
Starting a new cycle while your hormone levels are still recovering from the previous one compounds the suppression and makes future recovery harder. It also prevents you from knowing whether the damage from the previous cycle was reversible. Confirm full recovery with blood work before starting any new cycle. "Feeling recovered" is not enough — the blood work must confirm it.
Tracking Recovery Over Time
Recovery is not a single event — it is a process. The best approach is to track key markers over multiple draws:
- Draw 1 (week 4-6) — Hormones only: TT, LH, FSH, E2, SHBG. This establishes whether recovery has started.
- Draw 2 (week 8-12) — Full panel: hormones, lipids, liver, kidneys, CBC, HbA1c. This confirms full recovery.
- Draw 3 (week 16, optional) — If Draw 2 shows incomplete recovery in any system, this follow-up tracks continued improvement.
Each successive draw should show improvement. If a marker plateaus or worsens between draws, that is a signal to investigate further rather than wait longer.
GearCheck Post-Cycle Assessment
When you upload your post-cycle blood work to GearCheck, the analysis automatically tracks recovery trends when you have prior draws in your history. The system compares your markers against your pre-cycle baseline and highlights:
- Whether hormone levels are trending toward baseline
- Whether organ stress markers have resolved
- Whether lipid recovery is on track
- Whether it is safe to consider a next cycle
This trend-based view is more valuable than any single blood draw in isolation because recovery is defined by direction, not a single snapshot.
