+1. This mirrors my journey exactly. The Peptide Sciences discussion here is so valuable.

Bookmarked 📌 The Peptide Sciences info in this thread is essential. Coming back to this for sure.

Slightly tangential to Peptide Sciences quality but Dr.BariatricHTX reminded me — does anyone have experience combining this with metformin?

I know it is not exactly on-topic but it seems related enough to ask here rather than starting a new thread. Apologies if this has been covered — I did search first.
