Monitoring: what the literature does and does not say
For an approved drug, the prescribing information is where monitoring is set out — in its Warnings and Precautions section, whose headings are listed above for each label, and in its dosing and specific-populations sections. This page lists those headings so a prescriber can see what the label covers; it does not restate the label, and the label, not this page, is the authority.
Compounding: where it stands
Today's position for Tesamorelin: Rx (FDA-approved as Egrifta). An FDA advisory committee's vote is a non-binding recommendation; until FDA acts, a vote does not change what may be compounded. Our explainer on the 503A and 503B categories sets out what each status means, and the regulatory tracker is updated as FDA acts.
The evidence
A 44-amino-acid synthetic analogue of human GHRH with a trans-3-hexenoyl group added at the N-terminus, which stabilises it; it makes the pituitary release more of its own growth hormone.
The encyclopedia entry lists the human and animal studies we hold, each with its PMID.
What this page leaves out
Doses, regimens and titration. For an approved drug those belong to the prescribing information, linked above; restating them here would create a second, unmaintained copy.
