Cosmetic Peptide Comparison: BPC-157 vs TB-500, IGF-1 vs IGF-1 LR3, Semax vs Selank, GHRP-2 vs Ipamorelin Cosmetic Peptide Comparison: BPC-157 vs TB-500, IGF-1 vs IGF-1 LR3, Semax vs Selank, and GHRP-2 vs Ipamorelin At a glance BPC-157 half-life / approximately 4 hours (subcutaneous or intramuscular) TB-500 half-life / longer systemic distribution, dosed 2-4 mg twice weekly IGF-1 LR3 active window / up to 20 hours vs ~20 minutes for native IGF-1 Semax mechanism / upregulates BDNF and dopamine receptor sensitivity Selank mechanism / enhances GABA-A tone and reduces IL-6 by ~30% in animal models GHRP-2 GH pulse / strong but co-elevates cortisol and prolactin Ipamorelin GH pulse / selective
B12 fortified foods, such as cereals, nondairy milk, and nutritional yeast
This is why B12 injections are included as standard in the Phentermine program and complement lipotropic injections
This is uncommon but might contribute to symptoms in some patients, particularly those taking certain medications like diuretics
