Enclomiphene citrate is the trans-isomer of clomiphene citrate, a well-established SERM. In the published literature the compound is described as an antagonist at estrogen receptors in the hypothalamus, modulating the negative feedback loop of the hypothalamic-pituitary-gonadal (HPG) axis and increasing the release of gonadotropin-releasing hormone (GnRH), luteinizing hormone (LH) and follicle-stimulating hormone (FSH).
The two isomers of clomiphene behave differently: the cis-isomer (zuclomiphene) shows estrogenic activity and a much longer half-life, while the trans-isomer (enclomiphene) is responsible for the anti-estrogenic activity at the hypothalamus. This is why enclomiphene is studied and supplied as a purified isomer rather than as the mixed compound. The peer-reviewed references are listed below and every reference can be opened and checked.
The current Enclomiphene citrate batch (EN-S2-2026, 12.5 mg/ml solution) was analysed by an independent laboratory in July 2026 with identity confirmed and purity certified above the 96% HPLC acceptance threshold. The full report, sample photos and the link to verify the certificate in the laboratory database can be reached through our lab testing page. A certificate that can be checked directly in the lab database cannot be edited or fabricated, unlike a self-issued PDF. How to read an HPLC certificate is explained on the lab testing page.
Enclomiphene citrate is the trans-isomer specifically. Many products on the market contain the mixed isomer (clomiphene) rather than the purified trans-isomer. Without independent lab testing, isomer purity cannot be verified.
At Camo Chem, every batch is tested by an independent 3rd party laboratory. The full Certificate of Analysis is published for every batch and the results can be verified directly with the lab. Camo Chem does not self-certify. Ever.
A fair question for any supplier: who tests their products?

Enclomiphene citrate, the trans-isomer of clomiphene, was characterised in Phase II research as a selective estrogen receptor modulator acting on the hypothalamic-pituitary-gonadal axis, with LH and FSH as the measured endpoints.
View on PubMed →The same study describes the pharmacological profile of the purified trans-isomer as distinct from mixed clomiphene citrate, which contains the long-lived estrogenic cis-isomer (zuclomiphene).
View on PubMed →A meta-analysis of SERM research pooled the published data on this compound class and its effect on gonadotropin-driven endpoints across studies.
View on PubMed →Great product foul taste but as to be expected
The difference hasn’t been huge but it’s been there without changing my training or diet I’ve lost 4kg in a month and a half and bench up from 105 to 120 these are still semi newbi gains tho
Real deal, great way of increasing test after a cycle. My balls got back to normal around 4 weeks in. Love this company it’s most legit in europe. I can also confirm the lgd3033 they sell is also legit !!
Good product, delivery could be improved with NDD option
The best products, and the highest quality, you can’t fail with this company
Excellent service, would do business again.
Excellent service, fast international shipping! And legit product
Speedy issue of order & delivery. Recommended company and product.
Feel like I'm now testosterone with a body, rather than a body with testosterone

Enclomiphene citrate is a selective estrogen receptor modulator (SERM) with CAS number 7599-79-3. It is the purified trans-isomer of clomiphene citrate and has been the subject of published Phase II and Phase III research. It is sold exclusively as a research compound.
As an antagonist at estrogen receptors in the hypothalamus. By modulating the HPG axis feedback loop, the compound is associated in the literature with increased release of GnRH, LH and FSH. The references are listed on this page.
Clomiphene citrate is a mixture of two isomers: enclomiphene (trans) and zuclomiphene (cis). Enclomiphene is the purified trans-isomer, responsible for the anti-estrogenic activity at the hypothalamus. The cis-isomer (zuclomiphene) has estrogenic activity and a much longer half-life, which is why the two isomers are studied separately.
Every batch meets a minimum of 96% purity as verified by HPLC. Testing is performed by an independent 3rd party laboratory. The CoA for the current batch (EN-S2-2026) is available from this page.
By an independent laboratory with no commercial relationship with Camo Chem. Camo Chem does not self-certify. Every CoA can be verified directly in the testing lab database via the link on the batch report page.
