Sermorelin + Ipamorelin + SS-31 + Collagen Sarcopenia Support Stack

The first thing to understand is that no peptide in this stack has validated human dosing for treating sarcopenia — sermorelin and ipamorelin are GH-releasing secretagogues studied mostly for other endpoints, SS-31 is an experimental mitochondrial peptide, and none is an approved sarcopenia therapy, so no specific injectable regimen is recommended here and any use should be medically supervised. Growth-hormone-axis peptides are sometimes dosed at night to mimic physiological GH pulses, but raising GH/IGF-1 in older adults carries real trade-offs and does not reliably translate to functional strength gains. The evidence-based core is non-negotiable: progressive resistance training 2-3 times weekly plus roughly 1.2-1.6 g of protein per kg of body weight per day (spread across meals, with adequate leucine), alongside vitamin D repletion where deficient. Collagen peptides (around 10-15 g) can supply connective-tissue amino acids but are a nutritional adjunct, not a muscle-building driver. Treat the peptides as speculative add-ons layered on top of training and protein, never as replacements for them.
