Safety Profile
Side effects, contraindications, monitoring protocols, and what triggers a pause.
General safety profile
Peptide therapy, when prescribed appropriately and monitored with lab work, has a well-established safety profile. Most side effects are mild and transient: injection-site irritation, headache, flushing, and temporary fatigue during the first week of use.
Serious adverse events are rare but possible, which is why every protocol requires lab monitoring. Your clinician is watching for markers that would indicate the protocol should be adjusted or paused.
What we monitor
Follow-up labs track the same markers as your baseline panel, plus protocol-specific markers. For sermorelin: IGF-1 trend, fasting glucose (GH affects insulin sensitivity). For NAD+: metabolic panel trends. For GHK-Cu: inflammatory markers and copper levels.
Your clinician also reviews subjective reports — sleep quality, energy, recovery, side effects — but lab values are the decision-making authority. How you feel matters. What your blood says decides what happens next.
Contraindications
We do not prescribe peptide therapy to patients with active cancer or history of cancer (growth hormone stimulation is contraindicated), pregnant or nursing patients, patients with untreated hypothyroidism, or patients with known hypersensitivity to specific compounds.
Each peptide has additional specific contraindications listed on its product page. Your clinician reviews your full medical history during intake and may identify additional exclusion criteria based on your individual case.
When we pause a protocol
Protocols are paused or discontinued if follow-up labs show concerning trends: IGF-1 rising above the target range, glucose dysregulation, significant changes in hepatic or renal markers, or any marker moving in a direction that your clinician determines requires investigation.
A pause isn’t a failure — it’s the system working. The entire point of lab-based prescribing is that the data tells you when to continue and when to stop. We’d rather pause a protocol than ignore a lab flag.
Emergency protocol
If you experience a severe adverse reaction (difficulty breathing, severe swelling, chest pain, signs of anaphylaxis), call 911 immediately. Do not wait for a clinician message.
For non-emergency concerns (persistent injection-site reactions, unusual fatigue, mood changes), message your clinician through the patient portal. Response times are typically within one business day, often faster.
