Sermorelin Not Working: Types Comparison
Reconstitution Error Incorrect bacteriostatic water ratio or air injection during mixing Peptide appears clear but produces no IGF-1 elevation after 4 weeks Discard current vial, reconstitute fresh peptide using 1:1 ratio with no air injection Most common fail
This comparison does not assign a generated winner or score.
- Reconstitution Error
- Incorrect bacteriostatic water ratio or air injection during mixing
- Peptide appears clear but produces no IGF-1 elevation after 4 weeks
- Discard current vial, reconstitute fresh peptide using 1:1 ratio with no air injection
- Most common failure mode. Technical error, not biological resistance
- Storage Temperature Excursion
- Vial stored above 8°C for >2 hours or left at room temperature overnight
- No visible change, but therapeutic effect absent or diminished
- Replace vial immediately. Temperature-damaged peptide cannot be salvaged
- Irreversible protein denaturation. Visual inspection unreliable
- Subtherapeutic Dosing
- Initial dose <200mcg never titrated upward
- Minimal or no IGF-1 increase, no subjective energy or recovery improvement
- Increase dose to 300–500mcg range and re-assess after 3 weeks
- Receptor saturation threshold not met. Increase dose before assuming non-response
- Oxidative Degradation
- Multi-dose vial used beyond 28 days or exposed to light
- Gradual decline in effect over weeks despite consistent dosing schedule
- Replace vial at 28-day mark regardless of remaining volume
- Peptide stability window exceeded. Efficacy declines even when refrigerated
- Insulin Resistance Interference
- Elevated fasting insulin or HbA1c >5.7% blocks hepatic GH-to-IGF-1 conversion
- Sermorelin increases GH but IGF-1 remains flat
- Address metabolic dysfunction first. Metformin, dietary intervention, or GLP-1 co-therapy
- Downstream receptor issue, not peptide failure. Requires metabolic correction
