What is Clomiphene Citrate 50 (Astera Labs)?
Astera Labs clomiphene in 50mg tablets, 50 to a sachet. The SERM that pushes hardest on restarting your own testosterone after a cycle.
Also sold as Clomid, Clomifene, Serophene or clomiphene citrate.
Clomiphene is a SERM. At the pituitary it blocks estrogen’s negative feedback, so your body reads estrogen as low and raises LH and FSH to compensate. That signal is what restarts your own testosterone production. It is a mixture of two isomers, enclomiphene and zuclomiphene, and only the first does the useful work.
Clomiphene Citrate 50 benefits
- Raises LH and FSH strongly, which is the mechanism that restarts your own production
- The most established compound in post-cycle protocols alongside tamoxifen
- Long half-life, so one dose a day is the whole protocol
- 50mg tablets, which can be halved for the 25mg most protocols taper down to
Clomiphene Citrate 50 dosage
- Week 1 to 2
- 50mg per day, one tablet
- Week 3 to 4
- 25mg per day, half a tablet
- Gynecomastia
- Not the first choice, use tamoxifen or raloxifene
- Start after
- 2 weeks post long ester, 2 to 3 days post short ester
- Half-life
- Enclomiphene about 10 hours, zuclomiphene several days
- Protocol length
- 4 weeks, extended to 6 if bloodwork says so
The usual shape is higher for the first fortnight then tapered. Many protocols run it alongside tamoxifen rather than instead of it.
Do not run an aromatase inhibitor through post-cycle therapy. Recovery needs estrogen present, and suppressing it here works against the entire point.

Who is Clomiphene Citrate 50 for?
Anyone finishing a suppressive cycle who wants the option that pushes recovery hardest.
CLOMIMED 50 is the same strength from Deus Medical in a boxed blister. If the visual or mood side effects are a concern, enclomiphene removes the isomer that causes them.
How to use Clomiphene Citrate 50
Swallow one tablet with water at the same time each day. Splitting the dose achieves nothing. Begin only once the last compound has cleared.
