Can you take IGF-1 LR3 and Tesamorelin together?
Yes, with care — this combination needs a precaution.
IGF-1 LR3 and Tesamorelin can be taken together, but the combination needs a precaution.
Why these two interactSources for why these two interact: Jumps to this entry in the sources and references list at the end of the page.
These do NOT oppose each other — both push the GH/IGF-1 axis the same direction. Tesamorelin raises your own GH and IGF-1; IGF-1 LR3 adds exogenous IGF-1. Stacking is redundant, risks overstimulation, and the added IGF-1 can suppress natural GH via feedback, partly working against the tesamorelin.
What to do about itSources for what to do about it: Jumps to this entry in the sources and references list at the end of the page.
Same-axis redundancy, not synergy — don't stack without a clear reason and provider oversight.
TimingSources for timing: Jumps to this entry in the sources and references list at the end of the page.
No fixed separation window applies here. Keep the timing consistent day to day so any effect is easy to spot.

Check your whole routine, not just this pair
One pair rarely tells the whole story. DoseRoutine checks every combination in your stack at once — supplements, TRT, peptides, GLP-1s and prescriptions — and schedules the doses so timing conflicts like this one are handled automatically.
