GH-axis + recovery stack

TB-500 + Ipamorelin stack

A research-context overview of stacking TB-500 with Ipamorelin: the rationale, complementary benefits, side-effect overlap, and pharmacokinetic considerations. Educational only — never a recommendation.

Why this stack?

Pairing a Performance peptide like Ipamorelin with a Recovery peptide like TB-500 is one of the most common stack archetypes in the research literature. The Performance compound drives the GH/IGF-1 axis or anabolic signaling; the Recovery compound shortens the soft-tissue and inflammation tax of training, letting the anabolic signal land on healthier tissue. The two work on independent pathways, so timing concerns are minimal — most researchers dose them on separate clocks.

Recovery

Half-life considerations

TB-500 clears at roughly t½ 2.0 d, while Ipamorelin clears at roughly t½ 2.0 h. That is a wide PK separation: TB-500 provides steady tonic exposure while Ipamorelin produces brief pulses on top. Schedule the short-acting compound around the timepoints where its acute effect is most useful.
