Description
Enclomiphene 25mg per tablet, thirty tablets, 750 mg in total. This is the isolated trans isomer rather than the mixed citrate sold two listings over. No enclomiphene product holds FDA approval in the United States and all domestic supply is compounded, though the compound is not a controlled substance. Research use only, not for human consumption, adults 21 and over, with purchase restrictions by state.

Single isomer, not a mixture. That is the whole point of the listing, and it is also the thing an HPLC method has to demonstrate rather than assume for enclomiphene 25mg.
We file enclomiphene 25mg under the PCT listings. The parent shelf is anabolics.
What enclomiphene 25mg is, chemically
Clomiphene is a pair of geometric isomers about its central double bond. Enclomiphene is the E, or trans, isomer; zuclomiphene is the Z. They are the same atoms in the same connectivity with a different geometry, which makes them separable by chromatography and distinguishable by retention time rather than by mass.
Mass spectrometry alone cannot tell the two apart, since both weigh the same. Identity for a single-isomer product therefore rests on the chromatographic method and the reference standard, and that is exactly why the method is named on the certificate instead of being left implied.
Seven hundred and fifty milligrams
25 mg per tablet across 30 tablets is 750 mg. At $71.20 the arithmetic gives about $0.095 per milligram, which is the figure printed under the price. It sits well below the 1 mg and 0.5 mg ancillaries and well above the bulk oil solutions, and that ordering is driven by content per unit.
Price per milligram beats the price on the bottle and check the lab before you check the numbers cover how we compare listings and how we check them.
United States regulatory status
No enclomiphene product holds FDA approval in the United States, which makes it the exception on the PCT shelf, where the other compounds are approved generics. Enclomiphene supplied in this country comes from compounding pharmacies, and a compounded preparation is not an approved product. Enclomiphene 25mg is not a controlled substance. Approval records are at the FDA’s drug databases and the schedules at the DEA.
What the certificate of analysis covers
Two separate questions get answered on the certificate, and they are easy to confuse. Purity is reported by HPLC as a percentage of total peak area, which is a statement about the chromatogram: one large peak, and whatever else the detector saw. Identity is a different test, where mass spectrometry compares the measured mass against the mass the structure predicts. A sample can pass on identity and still carry a two percent secondary peak, so both figures are printed rather than the flattering one. Residual solvent for enclomiphene 25mg is reported in parts per million. The lot number on the container is what ties the paperwork to enclomiphene 25mg in front of you.
Our walkthrough of a certificate of analysis goes through the same document field by field.
What arrives
One sealed container of enclomiphene 25mg, labelled with the compound, the content per unit, the count or fill volume, and the lot number that matches the certificate linked on this page. Storage conditions are on the listing. The packing note names enclomiphene 25mg in full. We do not ship unlabelled containers, do not split lots across containers, and do not describe the contents as anything other than what they are.
No protocols, and why
We publish no dosing information, no administration instructions and no account of physiological activity for this compound or for anything else on this shelf. Staff will not supply it either.
That is a settled policy rather than a cautious mood. Enforcement in this category has turned on exactly that content: a page describing quantities and outcomes for a material is treated as promoting an unapproved drug whatever the footer says. Research use only is not a legal strategy, and the FDA has said so in writing sets out the detail. The FDA’s drug information section is the primary source.
We sell this item as a laboratory reference material, for research use only and not for human consumption. Adults 21 and over, with purchase restrictions by state: the product page lists the exclusions and the cart applies them. This is not a drug, a dietary supplement or a food, and it is not approved for administration to a person or an animal. Every lot certificate is published on the lab results page.
