Critical Drug Interactions

These interactions carry serious risk. Always inform your prescribing provider of ALL medications and supplements you take.

Methylene Blue + SSRIs/SNRIs

Methylene Blue inhibits monoamine oxidase and can cause serotonin syndrome when combined with serotonergic medications (SSRIs, SNRIs, MAOIs, tramadol). This interaction can be life-threatening. Never take methylene blue if you are on an SSRI or SNRI without explicit guidance from your provider.

GLP-1 Agonists + Oral Medications

Semaglutide and tirzepatide slow gastric emptying, which can affect the absorption of oral medications. Medications with narrow therapeutic windows (e.g., warfarin, levothyroxine, oral contraceptives) may need timing adjustments. Discuss with your provider.

Testosterone + Blood Thinners

Testosterone can increase hematocrit (red blood cell concentration) and may enhance the effects of anticoagulants. Regular CBC monitoring is essential, especially in the first 6 months of TRT.

MK-677 + Diabetes Medications

MK-677 can increase blood glucose and insulin resistance. If you are diabetic or on glucose-lowering medications (metformin, insulin, sulfonylureas), close blood glucose monitoring is required.

General Safety Principles

Always get baseline labs before starting any peptide therapy. Your provider needs reference values to monitor your response.
Start low, go slow. Most protocols use dose escalation for a reason — it reduces side effects and helps identify your optimal dose.
Source matters enormously. The same compound from a licensed pharmacy vs. a gray market vendor can have completely different safety profiles.
Report side effects to your provider. Don't try to self-manage concerning symptoms. Your provider can adjust dosing or switch compounds.
Follow monitoring schedules. Regular lab work catches problems before they become serious.
Don't stack compounds without guidance. Combining multiple peptides creates unpredictable interaction potential.
