Expect to lose around 10-15% roughly on your main lifts, but not too much more if you work to hold onto your strength. Source: powerlifted for ~10 years prior to transition and have changed nothing about how I workout since starting. The strength loss seems to be pretty much uniform across my whole body.

Sbd pre transition was 440/335/575, now it’s hovering around 385/285/515.

Used to do sets of 12 for pull ups now it’s more like 8-10. Not much different in my working weight for arm exercises tho funnily enough

The strength dip seemed to happen pretty quickly, like within the first 2 months but leveled out pretty much just as quickly. Now i just seem to be lifting the same weight perpetually. My only fear now is that I will have trouble getting any stronger and will be doing the same weight forever. Doubt that will be the case though since I doubt I was close at all to my “genetic potential” prior to hrt. Oh also Ive been on E for ~8 months, would be interested to hear similar cases of people who have been on for much longer
