ok so sust has 4 tests 2 short 2 long correct? so if one were to start of taking sust and shooting twice a week then the 2 long esters would take about 4 weeks to kick in, then the 2 short esters take will spike ur hormone levels within days, however at best the 2 short acting test esters will keep sustained test levels for 3 days tops! so it is only wise to shoot sust eod or ed until ur 2 long acting ester kick in, other wise the first 4 weeks using the sus and onlygetting short acting esters spikes will fuck u up if you only shoot once a week or twice a week, what will happen is ur levels will rocket up, then by day 3 they come down which leaves you open for labido problems,mood swings, acne and all other sides associated with gear, hope i explained that thoroughly enough for anyone to understand sustanon should be shot ed or eod for the first 4 weeks until the 2 long tests kick in, otherwise its kinda like shooting prop once or twice a week ya know
