Clomid PCT Dosage: 25 mg, 50 mg, 100 mg, and Frontload Protocols
Last updated: April 2026. Written by the Elite Bio Supply research team. Every product is sourced from verified pharmaceutical manufacturers, blister packed with batch identification, and inspected before dispatch.
This is a sub page of the Clomid PCT pillar guide covering only dosage. If you are looking for the full PCT context (mechanism, protocol, side effects, comparison to Nolvadex and enclomiphene), the pillar is the better starting point. This page is for researchers who already understand what Clomid does and need the dosage tiers, frontload options, taper schedules, and weight based adjustments in one place.
Quick answer (if you only read one paragraph)
The standard Clomid PCT dosage reported in published bodybuilding protocols is 50 mg daily for the first two weeks of a 4 week protocol, dropping to 25 mg daily for weeks three and four. Heavier cycles sometimes frontload with 100 mg daily for the first 3 to 7 days before stepping down to 50 mg. Light cycles can run 25 mg daily throughout. Long term hypogonadal monotherapy uses lower doses (12.5 to 25 mg every other day to daily). Side effect incidence climbs noticeably above 50 mg per day, which is why frontload protocols are bounded to a few days rather than maintained for weeks.

The three dosage tiers
Three dose tiers cover almost all reported Clomid PCT use cases.
25 mg daily. The low tier. Used for the final 1 to 2 weeks of a 4 week PCT to taper down before discontinuation. Also used throughout for very mild cycles (short duration, low total dose, low aromatization). Side effect incidence at 25 mg is meaningfully lower than at 50 mg in most reported protocols. The HPTA recovery effect is present but slower than at 50 mg.
50 mg daily. The standard tier. The dose reported in almost every bodybuilding PCT protocol for the first 2 to 4 weeks post cycle. Reliably suppresses estrogen feedback at the hypothalamus and drives LH and FSH recovery. Mood and vision side effect risk is real but tolerable for most researchers. This is the dose to default to without specific reasons to deviate.
100 mg daily. The high tier, used as a frontload for 3 to 7 days at the start of a heavier cycle’s PCT, then stepped down to 50 mg. Not a sustainable maintenance dose. Side effect incidence rises sharply above 50 mg per day, particularly mood shifts, headache, and visual disturbances. The frontload window is bounded specifically because zuclomiphene accumulates and the side effect profile worsens with sustained high dose.
Frontload protocols
Frontloading the first few days of PCT at 100 mg is reported in protocols for cycles with significant suppression: long ester testosterone protocols above 500 mg per week, nandrolone or trenbolone runs, or stacked oral plus injectable cycles. The logic is that the HPTA needs maximum signal early to begin restarting, and a high pulse early is more effective than a steady moderate dose throughout.
A typical frontload schedule:
| Day | Clomid |
|---|---|
| Day 1 to 3 (or 1 to 7) | 100 mg daily |
| Remainder of week 1 to 2 | 50 mg daily |
| Week 3 to 4 | 25 mg daily |
Researchers who run frontloads typically pair the protocol with Nolvadex 20 mg daily across all 4 weeks for breast tissue protection. See Clomid vs Nolvadex for PCT for the stack rationale.
For mild cycles, frontloading is generally not needed and adds side effect load without proportional recovery benefit. The HPTA response to clomiphene at 50 mg daily is already saturating in most researchers.
Taper schedules
Tapering Clomid down at the end of the protocol is standard practice in published protocols, though the rationale differs from the rationale for tapering anabolic compounds.
Why taper: to reduce the risk of estrogen rebound when the SERM block is removed and circulating estradiol returns to its post recovery level. A sudden discontinuation at high dose can cause a bounce in estradiol that drives transient gyno symptoms or mood disruption.
Standard taper: drop from 50 mg to 25 mg in week 3, hold 25 mg through week 4, then discontinue. Some protocols add a 12.5 mg week 5 step before full discontinuation; this is a minority approach and is more common in long term monotherapy taper than in PCT taper.
Aggressive taper: drop from 50 mg straight to discontinuation at week 4. Workable for short PCT protocols but reports more rebound symptoms than the standard taper.
No taper: running 50 mg daily for the full 4 weeks then stopping. Not recommended in current published protocols.
Weight based adjustments
Clomiphene PCT dosing is not strictly weight scaled in most published protocols, but body mass affects volume of distribution and steady state concentration enough to matter at the extremes.
Researchers under 70 kg: 50 mg daily often produces stronger effects than the typical reported response, including more pronounced mood and vision side effects. Starting at 25 mg daily and titrating up is reasonable.
Researchers 70 to 100 kg: the standard 50 mg daily is calibrated to this range. No adjustment needed.
Researchers over 100 kg: 50 mg daily may produce a milder effect than the typical response. Frontloading is more likely to be useful, and some protocols extend the 50 mg phase to 3 weeks before tapering to 25 mg.
These adjustments are general guidance from reported protocols, not strict scaling formulas. Bloodwork is the only reliable feedback loop. See the bloodwork section of the pillar guide for the recommended panels.
Cycle severity and dose selection
A rough framework for matching dose to cycle profile.
Light cycle (short SARM only, very low dose orals, short duration testosterone): 25 mg Clomid daily for 2 to 3 weeks. Sometimes Nolvadex alone is sufficient.
Moderate cycle (testosterone 300 to 500 mg/week for 8 to 12 weeks, single compound, no orals): 50/50/25/25 standard 4 week protocol with Nolvadex 20 mg daily.
Heavy cycle (testosterone above 500 mg/week, multi compound, oral inclusion, longer duration): 100 mg frontload for 3 to 7 days, then 50/50/25/25. Some researchers extend to 6 weeks.
Trenbolone or nandrolone heavy: longer recovery profile because of progestin activity and the longer ester half lives. PCT typically extends to 6 weeks, with frontload, and starts later (3 weeks or more after last administration for nandrolone decanoate).
The mapping is approximate. Cycle response is individual and bloodwork is the verification step.
Timing within the day
Clomiphene’s half life (enclomiphene 5 to 7 days, zuclomiphene approximately 30 days) means single daily dosing produces stable serum levels by the end of week 1. Time of day does not meaningfully affect efficacy.
Reported preferences in protocols:
– Morning dose: common, fits with daily routines, no specific advantage
– Evening dose: some researchers report better tolerance of mood side effects when dosed in the evening so peak serum levels coincide with sleep
– Split dose (12.5 mg twice daily for a 25 mg total): rarely reported, no documented advantage at PCT doses
Take with food to reduce mild GI effects in researchers who experience them. Otherwise timing is a personal preference.
Long term monotherapy dosing
Clomiphene monotherapy for hypogonadal management is a separate use case from PCT and uses lower doses over longer protocols.
Standard monotherapy dose: 25 mg every other day, or 12.5 to 25 mg daily.
Protocol length: 6 to 12 months, sometimes longer with periodic bloodwork checks.
Bloodwork cadence: baseline plus every 8 to 12 weeks during the protocol. Total testosterone, free testosterone, estradiol, LH, FSH, lipid panel, liver panel.
The rationale for the lower dose in monotherapy: zuclomiphene accumulates over multi month protocols, and the side effect curve at 50 mg daily over 6 months is significantly worse than at 25 mg every other day. Researchers who tolerate 25 mg every other day well sometimes step up to 25 mg daily; those who experience side effects step down to twice weekly or switch to enclomiphene monotherapy.
The current trend in long term protocols is to move from clomiphene to enclomiphene monotherapy specifically because of the zuclomiphene accumulation problem. See enclomiphene vs clomid for the comparison.
Side effect dose response
The dose response curve for Clomid side effects is non linear and accelerates above 50 mg daily.
| Dose | Mood side effects | Vision side effects | HPTA recovery effect |
|---|---|---|---|
| 12.5 mg daily | Low | Very rare | Mild |
| 25 mg daily | Low to moderate | Rare | Moderate |
| 50 mg daily | Moderate | Possible | Strong |
| 100 mg daily | High | Possible to common | Strong (saturating) |
| Above 100 mg | High | Common | Saturated; no additional benefit |
The HPTA recovery curve saturates at or near 50 mg daily in most researchers, which means doses above that produce side effects without additional benefit. This is why frontload protocols are bounded to short windows rather than maintained.

Splitting 100 mg tablets to 50 mg and 25 mg
EBS supplies clomiphene citrate as 100 mg tablets, 30 count. Researchers running 50 mg or 25 mg doses split tablets to achieve the target dose.
Splitting practice:
– 50 mg dose: halve a 100 mg tablet. Tablets are scored or splittable with a standard pill splitter. Variability per half is typically within 5 to 10 percent of the target.
– 25 mg dose: quarter a 100 mg tablet. Variability per quarter is wider, typically 10 to 20 percent of the target. For tighter control at 25 mg, dissolving the tablet in a measured volume of distilled water or 190 proof alcohol and dosing by volume is a reported workaround.
Practical note: for a standard 4 week PCT at 50/50/25/25, a 30 tablet bottle of 100 mg clomiphene supplies exactly the right dose. Week 1 to 2 uses 14 tablets (one half tablet daily for 14 days = 7 tablets, plus margin). Week 3 to 4 uses fewer. The 30 count pack is sized for one complete protocol with margin.
FAQ
What is the standard Clomid PCT dosage?
50 mg daily for the first two weeks of a 4 week protocol, dropping to 25 mg daily for weeks three and four. This is the dose reported in most published bodybuilding PCT protocols.
Is 25 mg of Clomid enough for PCT?
For light cycles (short duration, low dose, minimal HPTA suppression), 25 mg daily can be sufficient. For moderate or heavy cycles, 50 mg daily is the standard, with 25 mg used as the taper dose in weeks 3 and 4.
Can I take 100 mg of Clomid daily?
100 mg daily is used as a frontload for 3 to 7 days at the start of PCT for heavier cycles, then stepped down to 50 mg. It is not a sustainable maintenance dose because side effect incidence climbs sharply above 50 mg.
What is a Clomid frontload?
Running 100 mg daily for the first 3 to 7 days of PCT to accelerate HPTA restart, before stepping down to the standard 50 mg dose. Reported in protocols for heavier cycles.
Should I taper Clomid at the end of PCT?
Yes. The standard taper drops from 50 mg in week 2 to 25 mg in weeks 3 and 4 before discontinuation. This reduces the risk of estrogen rebound when the SERM block is removed.
How long should a Clomid PCT last?
Standard is 4 weeks. Heavier cycles may run 6 weeks. Anything beyond 6 weeks has diminishing returns and rising side effect risk.
When do I take Clomid each day?
Time of day does not meaningfully affect efficacy because of the long half life. Some researchers prefer evening dosing to time the peak with sleep. Take with food to reduce mild GI effects.
Is Clomid dosing weight based?
Not strictly. Researchers under 70 kg often respond more strongly to 50 mg and may start at 25 mg. Researchers over 100 kg may need an extended 50 mg phase. The standard dose is calibrated to roughly 70 to 100 kg.
Where can I buy clomiphene citrate in Canada?
EBS ships clomiphene citrate 100 mg, 30 tablets domestically across Canada. $50 CAD on sale. Sealed and labelled from a verified pharmaceutical manufacturer with batch identification. Canada Post 2 to 5 day shipping with seizure reship.
Can I split 100 mg tablets to 50 mg and 25 mg?
Yes. Halving produces 50 mg with 5 to 10 percent variability. Quartering produces 25 mg with 10 to 20 percent variability. For tighter control at 25 mg, some researchers dissolve tablets in measured volume and dose by volume.
