Epithalon 10mg vials - full vial each night or lower doses?

That is the right approach. Tracing the original studies shows why the older numbers were chosen and why they may not apply now. Old information keeps getting copied and creates confusion.

Your results match the current thinking. Older protocols are not wrong but probably stronger than needed. I always look for the smallest amount that still works and then adjust from there based on how I respond.

I prefer the lowest effective amount too and was not trying to go all out. Most sources still list 10 mg daily, even the ones that seem reliable. The mismatch between how I felt and how the instructions said I should feel made me look further. A recent thread here questioned the standard dosing numbers.

A continuously updated reference with peptide details and protocols works well for me. The people running it accept suggestions and keep adding new entries.

That sounds like a useful resource.

It has been my main reference. The owners put real effort into keeping everything current and they are active in the community.

The translation issue was not about units. The natural version requires one hundred times the amount of the synthetic one.

Thanks for the correction. I only remembered that a translation problem affected the recommended amounts.

The explanation was later adjusted to a tenfold potency difference, so 10 mg would become 1 mg rather than 100 mcg. One milligram worked well for me. I am unsure if 100 mcg would be enough, so given my age and background I stayed with 1 mg. A week after finishing the twenty-day cycle I still feel more clear and alert.
