[Question] TB-500 — what am I missing here

Question

Been lurking in c/darkspot for about 16 months and finally have something worth posting.

Short version: week 19, 0.5mg, and TB-500 is the bit I still cannot get a straight answer on. I have read the wiki, I have read the last 15 threads, and the answers split roughly down the middle.

What I actually want to know is whether the people saying it does not matter have measured it, or whether it is just repeated confidently. Happy to be told I am overthinking this — I probably am — but I would rather overthink it now than at week 25.

Week 2 for me and the honest summary is: 38kg down, the food-noise thing manageable, and I have thought about food maybe four times today.

My version of this: I was so worried about the injection that I put it off for eleven days. The injection is the easiest part.

name the compound precisely, TB-500 and Thymosin Beta-4 are not the same

Not to be pedantic but thymosin and TB-500 are being used interchangeably and they are not interchangeable in real life.

Removed a chain here. The rule is one line long and it is not negotiable.

purity and identity are two questions

u/iman_castellanos2 points·6 months ago

This is correct. Name it precisely.

u/bence_ibarra1 point·6 months ago

This is correct.

Adding to this: handling is doing more work than the comment implies.
