I don't have any specific research to hand to back it up, but certainly anecdotally bodybuilders (obviously taking much higher doses) have had problems with dangerously high Hct levels when using Test (amongst other AAS) but im not so sure this would be an issue at the sort of doesages cyclists are reported to have used.Arising from that, a geek question here, for those who are clued up on this topic: in 2011 there was no steroid part of the ABP so in theory you had more freedom to mess about with your T levels than, say, with your red blood cells. T has an impact on red blood cells, yes? Is that impact noticeable in the ABP's blood module? And is the effect different for injections and topical application?
(Or - in more general terms - why do cyclists use patches and gels when, as established upthread, injections are more efficient? Glow time?)
I think the question over why patches/gels over injections again comes down to doseages....typically injectable testosterone will come in oil dosed at between 200-400mg/ml. This is good for the kind of doseages used for strength and size gains where the typical user will inject twice per week to get doseage in the 400-800mg per week range....but as discussed upthread i think most pro cyclists would want to avoid going over 100mg per week due to the weight gains associated, with doses spread out daily to reduce glow time....you could see how it would be problematic/impractical to draw up such small doses of oil based T for injection....and if you're getting the dose you need/want from the gels then it makes sense to avoid the added risks that would come with daily injections.
