Peptide Safety Card
A preview drawn from Peptide Fundamentals. The complete card is included free with every course enrolment.
The Fast-Fail matrix
When to stop all stacking
- CGM unstable
- IGF-1 elevated
- Estradiol off-range
- Ferritin <30 or >300
- CK persistently elevated
The rule: one failure, correct it first. Two or more, stacking is predictably unsafe. Stop immediately.
Golden rules
- One metabolic lever at a time
- Correct labs before escalation
Contraindications example: GH-axis peptides
Tesamorelin · CJC-1295 · Ipamorelin · hCG
- Active malignancy or any cancer history
- Hormone-sensitive cancers (hCG)
- Pregnancy: Tesamorelin is Category X
Core safety lab: IGF-1
Required before any GH secretagogue. Elevated baseline means an absolute stop.
