1 Psychology of addiction Lecture 18 Anabolic Androgenic Steroids


3 The government's expert advisers on illicit drugs yesterday warned of the growing use of anabolic steroids by boys as young as 12 as they confirmed they are reviewing the legal status of ecstasy as well as cannabis. The Advisory Council on the Misuse of Drugs is to write to the home secretary, Jacqui Smith, voicing grave concerns about the growing abuse of anabolic steroids which are now being used by "tens of thousands" of bodybuilders and teenagers. It had been estimated that there were tens of thousands of people using steroids to improve the results of training regimes to make themselves look more muscular, said Professor David Nutt, chairman of the council's technical committee. Steroid users, rather than heroin injectors, were now the main clients of needle exchanges, the committee heard. Those who used anabolic steroids were often oblivious of the risks, which included acne, breast enlargement, sterility, liver tumours and hepatitis, the council chairman, Professor Sir Michael Rawlins, said. He added: "It can also make the testicles wither - which is probably not what the users want." (From Guardian 2007)

4 The latest figures show that 200,000 people in Britain have tried anabolic steroids, with 42,000 saying they have used them in the last year and 20,000 in the previous month. Home Office controls on anabolic steroids are aimed at suppliers and traffickers and it is not an offence to possess them to enhance performance. Lord Victor Adebowale, chief executive of the drugs charity Turning Point, said elite athletes knew what they were doing using steroids, but their increasing use by boys as young as 12 and 13 was extremely worrying. "They do it because they want to be in boy bands and get girls," he said. The advisory council, which was meeting in public for the first time in its 36-year history, is also to press the government to ban 26 anabolic steroids currently proscribed by the World Anti-Doping Agency, which controls the use of illicit substances in sport. Council members said action was needed in the run-up to the 2012 Olympics. Some members claimed the council would be better off looking at the anabolic steroid problem than spending two days in February debating whether cannabis should be regraded from class C to class B (From Guardian 2007)

5 Effects increase muscle size, muscle mass, strength - anabolic have masculinizing properties - androgenic also used therapeutically - for anaemia, thrombosis, and to build muscle for the bed-ridden addictive?

6 Demonstration of effects Bhasin et al. Healthy men 18-35, prior weightlifting experience, but hadn't taken steroids given monthly treatments testosterone, with another drug to suppress endogenous testosterone

7 Demonstration of effects lower (20-50 mg) doses --> testosterone levels below baseline 125-mg dose --> testosterone at baseline 300 and 600mg dose --> testosterone 2-4 times baseline (all anabolic steroids either contain testosterone, or are testosterone derivatives)

8 Muscle strength & volume following chronic testosterone administration to men



11 taken orally or intramuscularly endurance athletes and sprinters: low doses bodybuilders and strength athletes: up to 100 x therapeutic dose often use more than one at a time - called stacking supposedly enhances effectiveness

12 often cycled - take for 6-12 weeks then abstain: supposedly: minimises tolerance reduces occurrence of side effects maximises performance avoids detection another technique combined with cycling is pyramiding -- increase dose gradually till midpoint of cycle then decrease again supposedly reduces withdrawal

13 1. THE DOWNHILL RUN STACK Very high strength and very high size gains. The following cycle is designed with male, weighing 110KG, experienced steroid user, in mind. To adjust for the proper dosage for your weight, figure a factor of 10% / 10KG of body weight. Example: If you weigh 120KG, increase the dosage 10% (or to the closest possible dosage). Week Anadrol Sustanon Deca Dianabol Primobolan mg/day mg/weekmg/week mg/daymg/week 1 50 750 100 - - 2 50 500 100 - - 3 50 500 300 - - 4 50 250 400 - - 5 50 - 400 50 100 6 - - 300 50 200 7 - - 200 50 300 8 - - 100 30 300 Juice needed: 40 tabs of Anadrol 8 vials of Sustanon 250 mg/vial 10 amps of deca 200 mg/amp 300 tabs of Dianabol 9 vials of Primobolan 100 mg/vial

14 oral steroids potentially metabolised too fast in liver to act specially designed to avoid this problem they are based on testosterone

15 Chemical structures of some commonly abused anabolic steroids


17 initially mainly used by Soviet Union and Eastern bloc countries in 1950's by both men and women gained popularity in US for this purpose by mid 80's use widespread among even amateurs and even in schools law passed so that could only be obtained on prescription now banned by many sports organisations

18 The law Anabolic steroids are Class C drugs to be sold only by pharmacists with a doctor's prescription. It's legal to possess or import steroids as long as they're for personal use. But possession or importing with intent to supply (which includes giving them to friends) is illegal and could lead to 14 years in prison and an unlimited fine. Cost Prices can vary from region to region. Approximately £20 for 100 tablets. The prices given here are an average of street prices reported from 20 different parts of England.

21 How? theory is they act at androgen receptors, present in cytoplasm of skeletal muscle (and many other places) androgens bind, and activate receptor, which moves to cell nucleus and regulates DNA transcription increases protein synthesis and muscle growth


23 Steroid design issues testosterone can be converted in some tissues to dihydrotestosterone (DHT) by 5 -reductase this has androgenic effects - so is to be avoided as want the anabolic effects (doesn't happen in skeletal muscle)

24 Steroid design issues testosterone can be converted to estradiol by aromatase (aromatisation) normal process, mediating testosterone effects on CNS this has feminising effects - so is also to be avoided

25 A problem for the theory some argue that normally androgen receptors already saturated -- so how can steroids work on them? alternative mechanisms: possible steroid treatment induces receptor expression in muscle possible that androgens are antagonists for glucocorticoid hormones - which are catabolic - decrease protein synthesis.



28 Side effects: physical - If you're female, you can get acne, extra facial hair, a deep voice, shrinking breasts, an enlarged clitoris, an increased risk of menstrual problems and changes in sex drive. - You could experience dramatic mood swings. - You may find that you start getting paranoid and confused, along with having trouble sleeping. - Steroids can also give you high blood pressure and increase your risk of liver failure, stroke or heart attack.

29 Side effects: physical - Users claim the drug makes them feel more aggressive. Normally calm people can become irritable and aggressive, or even violent, and they can experience mood swings. - If you're young, abuse of anabolic steroids can stop you growing properly. - Injecting any drug can cause vein damage, ulcers and gangrene particularly with dirty needles. Shared needles and other injecting works can help the spread of HIV and hepatitis virus infections. - If you're male, regular use can lead to erection problems, growing of breasts, becoming sterile and developing acne. It can also make your testicles shrink.

30 Side effects: physical some common (e.g. acne) others rare (peliosis hepatitis) many reversible (cardiovascular effects) which occur depend on age, sex of user, steroid type, dose, pattern and duration of use can stunt younger users as prematurely closes epiphyses



33 Side effects: behavioural increased irritability and aggression? Sydney has recently witnessed two particularly brutal murders by users of anabolic steroids. One man with recent paranoid tendencies took a claw hammer and battered his wife to death, and then shot himself. In the second murder a man met a woman he knew at a nightclub and they went to the stairwell of a nearby hotel. In the man's words "something snapped" and he murdered the woman. Experienced police described it as the most brutal attack they had encountered. In both these murders the level of aggression and violence fits the descriptive term steroid rage ("roid rage").

34 Side effects: behavioural increased irritability and aggression? controlled studies produce mixed results: very dependent on individual Pope et al (2000): 84% almost no change 12% mild mania 4% strong mania differential susceptibility?

35 Side effects: behavioural addictive? reported in users (DSM criteria) take more than intended can't cut down even though want to spend much time obtaining and using continue use despite problems use causes replace other activities with substance use

36 Side effects: behavioural addictive? to some extent -- users show: withdrawal symptoms -- fatigue, depression, insomnia, restlessness, anorexia, decreased libido, dissatisfaction with body image, desire for more steroids(!) but no big studies so don't know how common this is... symptoms could be rare... or just unreported

37 Side effects: behavioural addictive? laboratory studies: systemic testosterone produces a place preference in mice so does testosterone in nucleus accumbens this is blocked by D1/D2 antagonist -flupenthixol accumbens supposedly helps mediate reward


39 Side effects: behavioural addictive? yes but.... doesn't produce euphoria, or elicit cravings during withdrawal so perhaps initially reinforcing because of effect on body image - only get dependence in people for whom this is important - not because it is psychoactive maybe with repeated use "true" dependence develops?
