MK-677 at 20–25mg daily provides sustained IGF-1 elevation required for chondrocyte proliferation. Cartilage lacks blood vessels and depends entirely on synovial fluid diffusion of growth factors. Pair with glucosamine sulfate (1500mg daily) and vitamin C (1000mg daily) to provide the substrates (glycosaminoglycans, collagen precursors) that chondrocytes need for matrix synthesis. Expect 8–12 weeks minimum; cartilage regeneration is the slowest tissue repair process in the body.

TB-500 at 2–2.5mg twice weekly for three weeks targets actin upregulation in regenerating muscle fibers. Scar tissue forms when fibroblasts dominate the repair process instead of myoblasts. TB-500 shifts the balance toward functional muscle regeneration. Start within 72 hours post-injury if possible; the peptide's effect is strongest during the proliferative phase of healing (days 3–21). Avoid NSAIDs during this window. They suppress the prostaglandins required for satellite cell activation.

BPC-157 is the primary candidate. Chronic tendinopathy involves failed angiogenesis and incomplete collagen maturation at the injury site. The peptide's VEGF mechanism directly addresses both factors. Subcutaneous injection near the affected tendon at 250–500mcg daily for 4–6 weeks aligns with the tissue remodeling timeline. Combine with eccentric loading exercises (the gold standard for tendon rehab) to mechanically stimulate collagen fiber alignment while BPC-157 enhances vascular supply.

Add a growth hormone secretagogue and reduce your caloric deficit slightly. The plateau likely reflects adaptive thermogenesis (reduced metabolic rate) and increased muscle protein breakdown. Both of which GLP-1 agonists don't address. CJC-1295/Ipamorelin or MK-677 maintains anabolic signaling and prevents the metabolic slowdown that occurs when the body starts sacrificing muscle. Research from the Journal of Clinical Endocrinology & Metabolism found that subjects using GH secretagogues during prolonged deficits maintained 92% of lean mass versus 78% in placebo, which translates to 60–100 additional calories burned per day from preserved muscle tissue.

This is expected. The mechanism (appetite suppression) becomes less relevant as ghrelin stays elevated regardless of peptide use and adaptive thermogenesis dominates. Switch to a metabolic modulator like tesofensine or add survodutide if available. Tesofensine increases resting metabolic rate independent of appetite, which directly counteracts the thyroid downregulation and NEAT reduction that occur below 15% body fat. Alternatively, take a 10–14 day diet break at maintenance calories to reset leptin signaling and metabolic rate, then resume the deficit with a different peptide stack.

Use a growth hormone secretagogue as the primary peptide and control the deficit through diet alone. GLP-1 agonists will cause muscle loss if protein intake and training stimulus aren't sufficient. The appetite suppression works so effectively that many users under-eat protein without realising it. A 180-pound male at 12% body fat needs 180–200g protein daily to maintain nitrogen balance in a deficit. Stack CJC-1295/Ipamorelin with high-frequency resistance training (4–5 sessions per week) and keep the caloric deficit modest (300–400 calories below maintenance). Expect 0.5–0.7 pounds of fat loss per week. Slower than GLP-1 protocols but with near-zero muscle loss.
