Week 6 update. 22kg down from the start, muscle cramps basically gone since about week 46. Things that worked: consistency, protein at breakfast, walking more than I…
Trying to settle this properly because the thread from last year went in circles. The claim: HPLC matters. The counter-claim: it is measurement error. Both sides have…
Right, the method development question again, but with numbers this time. I have 15 data points over 32 weeks. The pattern is consistent enough that I do not think it…
PeptideMeter — community peptide analytics
Vendor-level purity averages over time, built from independent results rather than vendor claims. Transparent methodology, open dataset.

Quick one. Canada here. gradient works very differently where I live than in the threads that dominate the front page, and I keep seeing people confidently given advice…
I have had 17 orders now and I keep a table, so here is the honest summary rather than a vibe. Material has been consistent. Communication has not. Shipping has varied…

Been lurking in c/t2dglp1 for about 18 months and finally have something worth posting. Short version: week 30, 10mg, and method development is the bit I still cannot…
