Product Information Boldenone Cypionate Item No. 15158 CAS Registry No.: 106505-90-2 O Formal Name: 17β-hydroxy-androsta-1,4-dien-3-one O cyclopentanepropionate MF: C27H38O3 FW: 410.6 H Purity: ≥95% Stability: ≥2 years at -20°C H H Supplied as: A crystalline solid λ O UV/Vis.: max: 244 nm Laboratory Procedures For long term storage, we suggest that boldenone cypionate be stored as supplied at -20°C. It should be stable for at least two years. Boldenone cypionate is supplied as a crystalline solid. A stock solution may be made by dissolving the boldenone cypionate in the solvent of choice. Boldenone cypionate is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide, which should be purged with an inert gas. The solubility of boldenone cypionate in these solvents is approximately 15, 5, and 25 mg/ml, respectively. Boldenone cypionate is sparingly soluble in aqueous buffers. For maximum solubility in aqueous buffers, boldenone cypionate should first be dissolved in ethanol and then diluted with the aqueous buffer of choice. Boldenone cypionate has a solubility of approximately 0.3 mg/ml in a 1:2 solution of ethanol:PBS (pH 7.2) using this method. We do not recommend storing the aqueous solution for more than one day. Boldenone is an anabolic androgenic steroid and synthetic derivative of testosterone that was originally developed for veterinary use.1 It can increase nitrogen retention, protein synthesis, and appetite, and also stimulates the release of erythropoietin in the kidneys.1 Boldenone cypionate was synthesized as an ester of boldenone in an attempt to alter boldenone’s very long half-life.2 Anabolic androgenic steroid compounds such as boldenone cypionate have been used illicitly by bodybuilders and other athletes.3 This compound is intended for forensic and research purposes only. -

Development and validation of NMDA receptor ligand- gated ion channel assays using the Qube 384 automated electrophysiology platform Abigail Marklew, Juha Kammonen, Emma Richardson & Jonathan Mann Saffron Walden, Essex, UK Abigail Marklew, Juha Kammonen, Emma Richardson and Gary Clark Saffron1 ABSTRACT Walden, Essex, UK 2 MATERIALS AND METHODS Ligand-gated ion channels are of particular interest to the pharmaceutical industry for the Cell Culture: HEK-NMDA NR1/N2A receptor cells were produced at Charles River Laboratories and treatment of diseases from a variety of therapeutic areas including CNS disorders, respiratory are commercially available. All cells were grown according to their respective SOPs as developed by disease and chronic pain. Ligand-gated ion channels have historically been investigated using Charles River, except for the use of D-(-)-AP-5 as antagonist during induction. Cells were kept in a fluorescence-based and low throughput patch-clamp techniques. However the development of the serum-free medium in the cell hotel on the Qube instrument for up to 4 hours during experiment. Qube 384 automated patch-clamp system has allowed rapid exchange of liquid and direct Induction: Cells were induced 24 h prior to use using 1 µg/mL tetracycline and 100 µM D-(-)-AP-5 in measurement of ion channel currents on a millisecond timescale, making it possible to run HTS neurobasal medium + 10% dialysed FBS. campaigns and support SAR with a functional readout. Solutions: The following extracellular saline solution was used (mM): 145 NaCl. 4 KCl, 10 HEPES, 10 Glucose, 2 CaCl2, pH7.4. Intracellular solution (mM): 70 KCl, 70 KF, 10 HEPES, 1 EGTA, pH7.2. -

PROJECT REVIEW “Characterization of the main metabolites of 17-methylstenblone and 17 methylmethenolone produced by human hepatocytes and liver fractions” Prof C. Ayotte, (INRS-Institut Armand-Frappier, Canada) New steroids openly appear on the market in products labelled with a rather confusing nomenclature. Once characterized, pharmaceutical grade products not being available, knowledge of the biotransformation pathways essential to an efficient detection of utilization by athletes is difficult to gain since administration to human volunteers should be restricted to the minimum. The alternative is a reliable in vitro model. Human hepatocytes, fresh or cryopreserved are now available commercially. We have successfully produced and identified phase I metabolites from incubations of human hepatocytes with different steroids, such as 17-methyldrostanolone and desoxymethyltestosterone (DMT). The aim of this project is to produce in vitro from human hepatocytes and liver fractions the metabolites of two steroids, the 17-methylated derivatives of stenbolone and its isomer methenolone. The principal metabolites will be synthesized and characterized by NMR and mass spectrometry. The characterization of metabolites will enable the identification of markers of utilization to be incorporated in routine testing methods. The approach for the chemical synthesis of metabolites will be shared with NMI insuring the distribution to other doping control laboratories. Improving the knowledge of steroid biotransformation is a further benefit from these studies. Characterization of 17-Methylstenbolone and 17-Methylmethenolone and Identification of Metabolites Produced by Human Hepatocytes and Liver Fractions WADA Project no. 11A16CA Christiane Ayotte, Philippe Räss, Alexandre Sylvestre, INRS-Institut Armand-Frappier Summary We have synthesized and characterized two designer steroids, 17α-methylmethenolone and 17α- methylstenbolone; the latter is proposed on the internet and two groups have reported different and contradictory results. -

Oh, but darling what if you fly? ii Stellenbosch University https://scholar.sun.ac.za ABSTRACT Depression has been recognised by the World Health Organisation (WHO) as the leading cause of disability, affecting an estimated 300 million people globally. To date antidepressants are prescribed as the first step in the treatment strategy. However, finding the appropriate antidepressant is often a lengthy process and is usually accompanied by side effects. A major and often unexpected side effect is reduced sexual function, which has been reported to aggravate depression and could possibly lead to poor compliance to medication. Sceletium tortuosum is a native South African plant, which has exhibited both antidepressant and anxiolytic properties. Although the exact mechanism of action remains to be elucidated, there are currently two hypotheses which attempt to explain it’s mechanism of action. -
