This peptide is not FDA-approved for the uses described. Compounded medications are not reviewed by the FDA for safety, effectiveness or quality, and availability varies by state and by pharmacy. Everything below describes what this peptide is studied for. None of it is a claim of proven benefit.
This is the one item in our catalogue we are most cautious about. It bypasses your body's natural controls entirely, carries a real risk of dangerously low blood sugar, and raises a theoretical concern about encouraging the growth of abnormal cells. Many physicians decline to prescribe it at all. Yours may be one of them, and that is a reasonable position rather than an obstacle.
How it works
Acts directly
Unlike the growth hormone peptides, which ask your body to produce more of its own, this acts directly and bypasses every natural control along the way.
Lasts much longer
It has been modified so your body cannot clear it or regulate it the way it would the natural version, leaving far more active for far longer.
Drives muscle growth
It switches on the processes behind muscle building and cell growth, which is why it is used.
Can drop your blood sugar
It behaves somewhat like insulin, so low blood sugar is a real and potentially serious risk, not a theoretical one.
What the evidence says
A version of this growth factor is FDA-approved for a rare childhood condition. This modified form is not approved for any use in people, has no trial support in healthy adults, and is banned in all tested sport.
What to expect
- Week 1
Close supervision, with particular attention to blood sugar.
- Weeks 2 to 4
Short course only. Extended use is not supported.
- After the course
A review is required before anyone considers repeating it.
Protocol
| Standard | Injection, dose set by your physician |
|---|---|
| Monitoring | Blood sugar monitoring is required, not optional |
| Course | Short and closely supervised |
Low blood sugar is the immediate risk. You need to know the warning signs and keep something sugary to hand before you start.
