Auch in diesem Jahr konnten wir wieder 2 schöne Veranstaltungen mit der GALERIA Kaufhof Leverkusen durchführen. Im Januar veranstalteten wir wieder die traditionelle Karnevalsmodenschau mit einem kleinen Rahmenprogramm und den aktuellesten Kostümtrends der Saison, vorgestellt von Mitarbeitern der GALERIA Kaufhof. Mit dabei waren das Kindertanzkorp der Roten Funken, die Funkenköpp, Prinz Karneval mit seinem Dudelsack sowie als Hauptakt Kuhl un de Gäng. Am . hieß es dann wieder in der Karnevalsabteilung "Rettet die Leverkusener Karnevalszüge in Wiesdorf und Opladen". Mit einem karnevalistischem Rahmenprogramm wurden wieder Spenden für unsere Züge gesammelt. Geschäftsführer Ralf Sturm überreichte in diesem Rahmen dem FLK-Präsidenten Uwe Krause einen gruoßen Scheck für die Züge. Eindrücke von den Veranstaltungen findet Ihr wie immer in unserer Fotogalerie .

Testosterone cypionate is a slow ester, resembling enanthate. The addition of trenbolone enanthate will provide the strongest AAS available. Enanthate ester means that less mg of trenbolone will be released, while injections shall be administrated twice per week (as with testosterone enanthate & cypionate). Fluoxymesterone is perhaps the strongest andgrogen available per os. It does not aromatize, therefore the subject does not observe any massive gains. What halotestin is so famous for is the tremendous strength it provides to the user, along with muscle density that comes out of it. Again sublingual use is a must, considering that fluoxymesterone is the strongest 17 alkylated oral available.

Urinary metabolites of boldenone (androsta-1,4-dien-17 beta-ol-3-one) following oral administration of boldenone (doses from 11 to 80 mg) to man were isolated from urine via XAD-2 adsorption and enzymatic hydrolysis with beta-glucuronidase from Escherichia coli. The isolated metabolites were derivatized with N-methyl-N-trimethylsilyltri- fluoroacetamide/trimethyliodosilane and analysed by gas chromatography/mass spectrometry with electron impact (EI) ionization at 70 eV. Boldenone (I) and four metabolites were identified after hydrolysis of the urine with beta-glucuronidase: 5 beta-androst-1-en-17 beta-ol-3-one (II), 5 beta-androst-1-ene-3 alpha, 17 beta-diol (III), 5 beta-androst-1-en-3 alpha-ol-17-one (IV) and 5 beta-androst-1-en-6 beta-ol-3,17-dione (V). Five further metabolites in low concentration were identified without enzymatic hydrolysis after treatment of the urine with potassium carbonate: 5 beta-androst-1-ene-3,17-dione (VI), 5 alpha-androst-1-ene-3,17-dione (VII), androsta-1,4-diene-3,17-dione (VIII), androsta-1,4-diene-6 beta,17 beta-diol-3-one (IX) and androsta-1,4-dien-6 beta-ol-3,17-dione (X). The identification of the metabolites is based on the gas chromatography retention index, high-performance liquid chromatography retention, EI mass spectrum, chemical reactions of the isolated metabolites, and synthesis of metabolites II, III, IV, VI and VII. The EI mass spectra of the bis-trimethylsilyl derivatives of boldenone and its metabolites display all intense molecular ions, M-15 ions and fragment ions originating from cleavage of the B-ring. The excreted metabolites can be separated in basic extractable labile conjugates and in stable conjugates. More than 95% of metabolites are excreted as stable conjugates.

Steroid isolation , depending on context, is the isolation of chemical matter required for chemical structure elucidation, derivitzation or degradation chemistry, biological testing, and other research needs (generally milligrams to grams, but often more [37] or the isolation of "analytical quantities" of the substance of interest (where the focus is on identifying and quantifying the substance (for example, in biological tissue or fluid). The amount isolated depends on the analytical method, but is generally less than one microgram. [38] [ page needed ] The methods of isolation to achieve the two scales of product are distinct, but include extraction , precipitation, adsorption , chromatography , and crystallization . In both cases, the isolated substance is purified to chemical homogeneity; combined separation and analytical methods, such as LC-MS , are chosen to be "orthogonal"—achieving their separations based on distinct modes of interaction between substance and isolating matrix—to detect a single species in the pure sample. Structure determination refers to the methods to determine the chemical structure of an isolated pure steroid, using an evolving array of chemical and physical methods which have included NMR and small-molecule crystallography . [2] :10–19 Methods of analysis overlap both of the above areas, emphasizing analytical methods to determining if a steroid is present in a mixture and determining its quantity. [38]
