Adding the clinical framing, because it changes how the question reads.
Third-party testing services for certificates of analysis besides Janoshik:
- Janoshik: Gold standard for peptide community, ~$143, 10-14 day turnaround
- Valitech: US-based, ISO 17025 accredited, ~$233
- Eurofins: Full pharmaceutical testing suite, more expensive but comprehensive
- ChemTox: Basic identity and purity testing, ~$103
Janoshik is the community standard but any ISO-accredited analytical lab can verify peptide identity and purity. The key is independence — don't rely solely on the vendor's own testing.

Same pattern here, and in the same order. Nothing to add that would improve it.

Adding the part of the answer the thread has not reached. Start from the measurement rather than the conclusion. Almost every disagreement here turns out to be two people measuring different things and comparing the numbers anyway.

View ResultsOne concrete data point for the thread. If you are going to change something, change one thing and give it long enough to express itself. Four weeks is the usual minimum for anything pharmacological on this board, and two weeks of data has told you almost nothing.
Following on from PharmHunterJen — and this may be the naive question:
How long did you give it before you decided it was working?
