Bij testosteron gebruik zou je ongeacht trainen spiermassa moeten aankomen. In onderstaand artikel van de New England Journal of Medicine zijn mannen in vier groepen gerandomiseerd en gevolgd.
Groep 1: Placebo zonder training
Groep 2: Testosteron zonder training
Groep 3: Placebo met training
Groep 4: Testosteron met training
The men received either 600 mg of testosterone enanthate in sesame oil or placebo intramuscularly each week for 10 weeks in the Clinical Research Center.
Uit de resultaten blijkt dat testosteron alleen al, zonder training, toename in kracht en spiermassa. De beste resultaten hadden uiteraard de testosteron met training groep.
Abstract
BACKGROUND:
Athletes often take androgenic steroids in an attempt to increase their strength. The efficacy of these substances for this purpose is unsubstantiated, however.
METHODS:
We randomly assigned 43 normal men to one of four groups: placebo with no exercise; testosterone with no exercise; placebo plus exercise; and testosterone plus exercise. The men received injections of 600 mg of testosterone enanthate or placebo weekly for 10 weeks. The men in the exercise groups performed standardized weight-lifting exercises three times weekly. Before and after the treatment period, fat-free mass was determined by underwater weighing, muscle size was measured by magnetic resonance imaging, and the strength of the arms and legs was assessed by bench-press and squatting exercises, respectively.
RESULTS:
Among the men in the no-exercise groups, those given testosterone had greater increases than those given placebo in muscle size in their arms (mean [+/-SE] change in triceps area, 424 +/- 104 vs. -81 +/- 109 square millimeters; P < 0.05) and legs (change in quadriceps area, 607 +/- 123 vs. -131 +/- 111 square millimeters; P < 0.05) and greater increases in strength in the bench-press (9 +/- 4 vs. -1 +/- 1 kg, P < 0.05) and squatting exercises (16 +/- 4 vs. 3 +/- 1 kg, P < 0.05). The men assigned to testosterone and exercise had greater increases in fat-free mass (6.1 +/- 0.6 kg) and muscle size (triceps area, 501 +/- 104 square millimeters; quadriceps area, 1174 +/- 91 square millimeters) than those assigned to either no-exercise group, and greater increases in muscle strength (bench-press strength, 22 +/- 2 kg; squatting-exercise capacity, 38 +/- 4 kg) than either no-exercise group. Neither mood nor behavior was altered in any group.
CONCLUSIONS:
Supraphysiologic doses of testosterone, especially when combined with strength training, increase fat-free mass and muscle size and strength in normal men.
Resultaten mbt spiermassa:
Body weight did not change significantly in the men in either placebo group (Table 4). The men given testosterone without exercise had a significant mean increase in total body weight, and those in the testosterone-plus-exercise group had an average increase of 6.1 kg in body weight — a greater increase than in the other three groups.
Fat-free mass did not change significantly in the group assigned to placebo but no exercise (Table 4 and Fig. 1). The men treated with testosterone but no exercise had an increase of 3.2 kg in fat-free mass, and those in the placebo-plus-exercise group had an increase of 1.9 kg. The increase in the testosterone- plus-exercise group was substantially greater (averag- ing 6.1 kg). The percentage of body fat did not change significantly in any group (data not shown)
Dus als je daadwerkelijk testosteron zou hebben gebruikt, dan zou je zowiezo 2-3kg minimaal moeten aankomen, ook al zonder exercise. Jij zegt wel te trainen en je dieet in orde is, dus dan zou je een gewichtstoename van 4-5kg moeten krijgen (gezien jij 500mg/pw gebruikt en in het onderzoek 600mg/pw)
