Ahh I 100% feel you, I hate having to choose between being cool and being comfortable!

As for the tape, floppy may work in your favour haha I think tape tends to work with less dense chests.

I’m in the UK so here we can’t easily get transtape but I used to buy sport tape or rock tape in the largest width (7.5cm or 10cm maybe) which was about £20. however now I buy it from Shein which is only £11 but the quality is lower. If you’re in the US you can use transtape and get whichever width is suitable for you, usually the widest is best for large chests! Alternatively any breast tape will work as these are all just KT (kinesiology tape) just rebranded.

I managed with the shein tape whilst being in and out of the swimming pool and this lasted 3/4 days before needing t replace it.

My method is start lying down, on each side - two pieces pulling each to the side (towards the armpit) and a long piece starting underneath and going over my shoulders to hold the weight, as I tended to feel it pulling without this piece. I haven’t heard anyone else use this method so if it doesn’t sound safe someone please let me know! I can draw a diagram for you later if it helps! You can also look at YouTube videos for tutorials for larger chests that may help, and unfortunately will take trial and error! It took me a whole roll to figure out a way that works for me.

The most important thing is leaving an ‘anchor’ about 1 inch which isn’t stretched at the start and end of each strip.

Also please be careful when taking it off, you can use any oil from the supermarket to help remove the adhesive and I don’t get blisters or sores unless I over tighten it initially

I have PCOS and am on a normal dose of T. I had the same worries as you about messing with my hormones since it took years for them to stabilise!! But haven’t had any problems so far so I’m glad I didn’t delay starting any longer.

My endocrinologist also had no issues starting me on Testosterone. He wants me to get regular blood tests but that’s the same for all his patients.

I already had a bit of body hair and a bit of a moustache pre-T so timeline wise that is the only thing that seems to have happened quicker than normal (I’m on T 4 months now and already have to shave). I haven’t had any other outwardly noticeable changes except my voice dropping a little.

I got myself a sleeveless hoodie which is decent enough to hide things

Or if small enough you could try tape although can be trial and error. I’ve had some success however only managed to reduce it rather than flatten completely
