As I experienced it recently:
Week 1-2: nothing really, could have been normal fluctuations.
Week 3-4: suddenly started noticing improvements.
Week 5-8: superman time! High libido, high energy, but also high sides (greasy, bloated, snoring, aggressive)
Week 9-...: stability. No more sides, but also no extreme libido. Just how a 40-y.o. should feel.
this is pretty much howo it goes on cyp.e will be a bit faster.
Would test cyp take longer?
Felt nothing yet only difference which may be just coincidence or phsicological but after training in morning muscles trained that day (back and biceps) seemed to still be pumped at bedtime.
Also have nearly zero muscular soreness when normally get quite a bit.
Other than that feel no different.
Diet will be 300 to 350 g protein. Maybe max 200g carbs or less.
yes cyp takes somewhat longer.
the improvement will not be slight or doubtable, it is "boom" kinda sensation.like supercharger kicks in.
be carefull when skin gets oily, bit acne can happen, those are best controled by diet and they go away.
but mood starts getting better imediately.overal i think mood has more to do with personal stuff ,how life is in general, but obviously when one starts cycle they excited and pumped up and looking forward this raises mood.
muscle soreness is not a sound indicator, but recovery for same workouts will be much faster.but if one trains harder than ever before,easy possible, then the recovery might take longer than before, simply bc is not used to such trainings.
after few week,it just goes boom.
yes pay attention to diet, do not pay attention to the ppl who sayyou can eat whatever you want(ofc you can, but its no good), some ppl after many years and lots muscle can eat things at certain times which makes it look like random and sweet diet, but dont mistake it for random they know exactly what they doing.
diet clean, only as much food as needed,its fuel, nothing else.
and the random cheat meal to see what happens.
enjoy it.play around with carbs, one day almost none, other day more, to see whats best.dont be afraid to eat some fats
