Im a peptide fanatic. Two years deep in peptides. Honest notes, just what each actually does in my body. CJC-1295 with Ipamorelin is my sleep fix. Used to wake five times a night, now I'm out cold till morning. GHK-Cu I'll never drop. Tore my forearm open on a bike chain last summer and it closed clean enough to surprise the urgent care guy. SS-31 is the weird one. Closest thing to the lights coming on, and my recovery between hard sessions got noticeably shorter. Semax flips my focus to overdrive. Great for deadlines, useless past early afternoon or I can't sleep. Tirzepatide slowed my gut so much I had to move my night supplements earlier, they just sit there otherwise. BPC-157 is the quiet one for joints and gut. I only notice it when I run out. Thing nobody warns you about with almost all of them: water weight. I'll wake up 5 pounds up and it's pure sodium, not fat. Took me way too long to stop letting the scale wreck my morning.

Had a traumatic spinal injury and SS31 helped tremendously with some side effects.. It also helped with my raging head aches.

Community Q&A

What does SS-31 do?
Community accounts describe SS-31 (elamipretide) as a mitochondria-targeting peptide that concentrates at the inner mitochondrial membrane — reducing oxidative damage and preserving mitochondrial function. Most accounts come from longevity-focused users treating it as foundational cellular protection rather than a performance compound. The most commonly described subjective effects: improved energy, reduced fatigue, and better recovery. SS-31 accounts frequently appear alongside humanin and MOTS-c in mitochondrial optimisation stacks — framed as infrastructure rather than enhancement.
How is SS-31 administered?
Subcutaneous injection appears in all community accounts for SS-31 — there is no established oral or nasal route in confessions. Daily dosing is the most common protocol. SS-31 is among the more expensive compounds in typical community accounts, and price is consistently cited as the limiting factor in access. Most accounts describe cycles of 30–60 days rather than indefinite continuous use, driven by cost as much as protocol design.
