Blood Test Schedule for a Steroid Cycle

The three structuring moments

Whatever the complexity of the cycle, blood monitoring organizes around three structuring moments. Adding them makes the cycle interpretable. Skipping them is going back to flying blind.

1. Baseline — before the first injection

Run 2 to 4 weeks before the first injection, this is the most complete panel. It serves as the personal reference for everything that follows — without it, no subsequent reading can be interpreted beyond the 'lab range'.

2. Mid-cycle — catch the drift

Run between week 4 and week 8 of the cycle (depending on total length), this captures the impact when the cycle is already installed (long esters reach steady state in 4 to 6 weeks ^[1]). It is there to catch the drift you do not feel (climbing hematocrit, drifting lipid panel, above-target estradiol) and to adjust before problems get settled ^[3].

3. Post-PCT — validate recovery

Run 4 to 6 weeks after the last SERM dose (Nolvadex or Clomid), this is the truth panel for PCT: it tells you whether the HPTA restarted ^[2]. Without it, the subjective 'I feel fine' can mask an LH at 0.5 IU/L and a testosterone at 280 ng/dL — i.e. persistent hypogonadism.

Detailed schedule by cycle type

Standard cycle — testosterone only, 12 to 16 weeks

Long cycle — 16 to 24 weeks

• Add an intermediate measurement (CBC + hematocrit +++) every 6 to 8 weeks to track the drift.
• If an oral is integrated on a window of the cycle, schedule a liver panel at the end of the oral.

Cycle with a strongly erythropoietic compound (boldenone, trenbolone)

• Tighter CBC monitoring (every 6 to 8 weeks) for the entire duration of the compound.
• Home blood pressure measurements once a week as a complement to the blood panel.

Cycle with 17α-alkylated orals

• Liver panel toward the end of week 4 if the oral runs 6 to 8 weeks.
• Liver panel 1 to 2 weeks after stopping the oral to verify recovery.
• Lipid panel at mid-cycle and post-PCT to follow the HDL/LDL impact.

SARMs cycle

Lighter blood monitoring than for steroids (not the same erythropoietic or lipid impact), but not zero. At minimum: baseline + post-mini-PCT hormonal panel. For strongly suppressive SARMs (LGD-4033, RAD-140), add a liver panel mid-cycle. See the PCT after SARMs guide.

Best practices for the draw

• Morning, fasted. Draw between 7 and 10 AM, after an overnight fast (water OK). That is the reference for hormones (testosterone, cortisol follow a circadian rhythm) and for the lipid panel (10 to 12 hour fast for reliable triglycerides) ^[4].
• No intense training in the 48 to 72 hours before. Heavy lifting raises AST (muscle origin) and can skew the hepatic read. Muscle recovery avoids this bias.
• Normal hydration. Dehydration artificially inflates hematocrit and skews global blood concentration.
• Always the same lab. Assay methods differ between labs (sensitive estradiol vs immunoassay, calculated free testosterone vs dialysis). To track a trajectory, stay on the same lab ^[4].
• For injectable testosterone, draw far from the injection. Ideally midway between two injections, to capture a representative value and not a post-injection peak.

Centralize your results: AnaProtoKol's blood work feature

A multi-year cycling career quickly generates a dozen, then several dozen PDF reports. Keeping them in a drawer or in an email folder does not let you see the trajectory — which is the essential of a blood panel.

What the feature gives you

• 8 panels, 59 markers. CBC, lipid, hepatic, male and female hormonal, kidney, thyroid, glucose/diabetes, cardiovascular markers.
• PDF lab import. Reports from US labs (Quest, LabCorp) and EU labs (Cerba, Eurofins, Synlab, Biogroup and others) are recognized and values pulled automatically — no manual re-entry.
• Graphical tracking with the baseline as reference. Each marker gets its own curve, with the thresholds and your personal baseline in the background — to read the trajectory at a glance.
• Alignment with the cycle journal. Panels automatically align with cycle phases (baseline, mid-cycle, post-PCT) — the reading becomes contextual.

Practical aspects in the US: ordering, cost, choosing a lab

With or without insurance

In the US, direct-to-consumer labs (QuestDirect, LabCorp OnDemand, plus specialist platforms like Marek Health, Discounted Labs, Private MD Labs and Ulta Lab Tests) let you order panels without going through your primary care, paying out of pocket. This is the standard route for cycle monitoring, avoiding the prior consultation. Through insurance and a primary care or TRT clinic, coverage can be partial to full depending on the plan.

Choosing a lab

• Verify that the lab offers sensitive estradiol (LC-MS/MS) — both Quest and LabCorp do, you just have to specify.
• Favor a lab whose reports are clear (explicit units, assay method stated).
• Stay with the same lab for follow-up panels — consistent methodology is a prerequisite for reading trajectories.

Cost ballpark

Out-of-pocket for a full self-ordered cycle panel (CBC, comprehensive metabolic, lipid, full hormonal with sensitive E2) typically lands in the $150 to $300 range through direct-to-consumer platforms. Additional markers (apoB, sensitive prolactin, non-blood calcium score) push the total up. With insurance through a TRT clinic, costs can drop substantially. This line item stays small versus the total cycle budget (compounds, gear, PCT) — the least debatable part of it.
