First Steroid Cycle: What to Choose, Dose and Length
Best Anabolic Steroids
Independent research & quality review desk
A first cycle has one job: to show you how your own body handles one compound, at one dose, for a fixed length, with blood work before and after. Everything people get wrong later starts here, usually because three compounds and an inhibitor were added in the first month. This page is the version with one variable.
- One compound: testosterone, as enanthate or cypionate.
- 250 to 300 mg a week, split into two injections.
- Eight to ten weeks, with the exit planned on day one.
- No aromatase inhibitor unless blood work asks for one.
- Baseline panel before, week 6, and four to six weeks after recovery.

What a first cycle is for
The result of a first cycle matters less than the information it produces. After eight to ten weeks on one compound you know three things: how much water you hold, how your blood pressure responds, and how quickly your own production comes back. None of that can be learned from a forum post, and all of it is needed before a second cycle makes sense.
That is the argument for keeping it boring: one ester, one dose, no oral, no second injectable, no inhibitor unless blood work asks for one.
Before anything: baseline
Without a baseline you cannot tell what changed. The panel is cheap relative to the course and takes one morning.
| Test | Why it matters |
|---|---|
| Total testosterone, LH, FSH | Confirms natural production was normal before the course, which is the reference for recovery |
| Estradiol, sensitive assay | Your own baseline estrogen, so a later rise can be judged against it |
| Full blood count with haematocrit | The number that rises on cycle and matters most for cardiovascular load |
| Lipid panel | HDL and LDL shift with androgens; the starting point decides how much room there is |
| ALT, AST | Liver baseline, essential if an oral is ever added |
| Blood pressure, at home, several readings | One clinic reading is not a baseline |
Choosing the compound
Testosterone, as a single ester, is the only sensible first choice. It is the hormone the body already makes, its effects and side effects are the best documented of any compound, and every other steroid is judged against it.
Three alternatives people ask about, and why they wait:
- Oral only. Liver enzymes rise within weeks, the course cannot run long, and the gains are mostly water and glycogen.
- Testosterone plus an oral. Doubles the variables. If something goes wrong in week three you cannot tell which compound caused it.
- A "mild" compound instead of testosterone. Every one of them still suppresses the axis, so the recovery question stays, minus the data that exists for testosterone.
Dose
250 to 300 mg a week is the common first dose. It is above replacement, well below the middle of the dose-response curve, and leaves somewhere to go later. Dose-response work in controlled settings shows strength and lean mass rising with the weekly amount, which is exactly why starting at the top of the range removes the room to learn.
| Weekly dose | What changes versus 250 mg |
|---|---|
| 250 to 300 mg | The first-cycle reference: clear effect, manageable water and pressure |
| 400 mg | More gain, more water and higher haematocrit |
| 500 mg | The common intermediate dose, not a beginner one |
| Above 500 mg | Side effects scale faster than results; no reason on a first cycle |
Ester and injection rhythm
Enanthate or cypionate, twice a week. The split keeps the level flatter than a single weekly injection, and most people report less mood swing and less acne on it. The label for testosterone cypionate gives an intramuscular half-life of about eight days, which supports twice-weekly dosing comfortably.
| Choice | Rhythm | Comment |
|---|---|---|
| Cypionate or enanthate | Twice a week, for example Monday and Thursday | The default first cycle |
| Propionate | Every other day | Faster in and out, more injections, suits a short block |
| Blend of esters | Twice a week | No advantage on a first cycle, harder to model |
Length
Eight to ten weeks. Shorter and the gains have not consolidated; longer and the recovery is harder without adding much. Gains typically flatten in the last two weeks on a fixed dose, and that flattening is the signal to stop, not to increase.
Aromatase inhibitor: when and when not
An aromatase inhibitor is not part of a first cycle by default. Taking one "just in case" lowers estrogen below where the body wants it, which costs libido, joints and mood, and makes the blood work harder to read.
| Situation | Action |
|---|---|
| No symptoms, estradiol in range | Nothing. Keep testing |
| Estradiol high on the week-6 panel, no symptoms | Discuss with a physician; dose adjustment often comes before adding a drug |
| Sensitive nipples, visible swelling | Act, with blood work, not by guessing a dose |
| Low libido, dry joints, low estradiol on the panel | Stop the inhibitor, not increase it |
Training and calories
The drug raises the ceiling; training and food decide where you land under it. On a first cycle the usual recommendation is the programme you already run, with volume held steady and progression written down, plus a small calorie surplus of 200 to 400 kcal and protein around 1.6 to 2 g per kg.
Adding training volume at the same time as adding a compound is the second most common mistake: if performance drops in week four, you will not know whether it was the extra sets or the drug.
Blood work during
| When | What to test |
|---|---|
| Week 6 | Total testosterone, sensitive estradiol, haematocrit, lipids, blood pressure log |
| Last week of the cycle | The same panel plus LH and FSH, to see how suppressed the axis is |
| Four to six weeks after recovery | Total testosterone, LH, FSH, estradiol - the only test that answers whether recovery happened |
Haematocrit and blood pressure move first. Dose-response work shows red cell production rising with the weekly dose, which is why a first cycle at 250 mg and a later cycle at 500 mg do not need identical monitoring.
The exit
Plan the end on day one. The last injection has a date, then a wait for the ester to clear, then a recovery protocol, then a blood test. For cypionate the wait is roughly two to three weeks; for propionate, three to four days.
The full protocol, with the timing table, is on the post-cycle therapy page.
What to expect
| Period | What happens |
|---|---|
| Weeks 1 to 2 | Little visible; libido and appetite often rise, some water appears |
| Weeks 3 to 4 | The level stabilises, strength climbs, blood pressure needs watching |
| Weeks 5 to 8 | The clearest gains of the block |
| Weeks 9 to 10 | Gains flatten on the same dose - the signal to end |
| After the last shot | A dip in energy and libido until clearance and recovery |
When to stop
Common first-cycle mistakes
- Starting at 500 mg because a forum said so, with no baseline.
- Adding an oral "for the kick" in week one, then adding an inhibitor in week two.
- Using an inhibitor as a precaution rather than a response to blood work.
- Changing training volume and calories and the compound at the same time.
- Skipping the week-6 panel, so nothing is known until after the course.
- Starting recovery on the day of the last injection instead of after clearance.
