The report says Biogen has a wide range of brand ambassadors‚ including the Nedbank Running Club. Team manager Nick Bester said that all supplements gifted to runners as part of the sponsorship agreement were double tested. “All of our products received from Biogen are tested by Informed Sports in London. They test every batch that we receive and only when we get the all clear from them do we pass it on to our athletes‚” he said. “This is a double stop gap. We don’t use that product but we don’t expect it to affect any of our runners.”
With use of an anti-aromatase, 600-750 mg/week of injected testosterone is a good dosage range for a novice. Without an anti-aromatase, it may be preferred to limit usage to 500 mg/week, although there can be risk of gynecomastia at doses even as low as 200 mg/week if no anti-estrogen is used. More advanced users may favor a gram per week. Still-higher doses such as 2 grams per week generally provide only a small further increment in performance, with that generally being noticeable only if a plateau has been reached at 1 gram per week. Amounts higher than this are employed by some pro bodybuilders but probably with only a slight further incremental effect.
