Personal lab monitoring and hormone health
For people receiving medically supervised growth-hormone or GH/IGF-1–pathway treatments, a clinician may recommend baseline and follow-up testing, such as IGF-1 and glucose or HbA1c, based on the medication and individual risk factors. Monitoring needs vary; blood tests do not establish that unapproved research peptides are safe for human use.
Explore Private MD Labs → PEPDEALS: 15% off eligible lab orders. This is personal clinical testing, not vendor product purity testing; discuss results and appropriate testing with a qualified clinician.

METHODOLOGY
How a vendor gets listed here
1. Request documentation
We ask every vendor for their independent lab reports — purity, identity, endotoxin, and sterility where applicable.
2. Verify the lab, not just the PDF
We check that the testing lab is real and independent of the vendor before a report counts toward a listing.
3. Publish what we found
Testing points, shipping, payment methods, and policies get listed as-is — including gaps, if there are any.
4. Recheck on a schedule
Vendor pages and coupon codes are revisited daily, not left to go stale after publishing.
