AAS & Peptides Can’t Remodel Your Bones
Most of your bone growth is over long before you even think about hormones. The mandibular symphysis fuses by the time you’re around 1 year old, which means your lower jaw stops having a true “growth plate.” The condylar growth that shapes your mandible slows down rapidly through adolescence and is basically done by your late teens. At the same time, craniofacial sutures in the midface and cranium gradually close during puberty and into early adulthood. Once those sutures are fused, there’s no mechanism left for lengthening or rotating bones naturally. The earlier the better (closer to puberty) supposedly. In reality most of the growth and maturation of bone tissue happens before their balls even drop (pre-puberty).
No Evidence
People love to cope with influencer before/after's, but the reality is there’s zero scientific proof that AAS or peptides can regrow or reshape facial bones after maturity. No peer-reviewed study has ever shown reopening of sutures or new growth in the zygomatic arches, mandible, or maxilla just from hormones. What gets passed around online is usually just differences in lighting, water retention, fat distribution, camera angles, or simply natural genetic variation. Even the most “convincing” examples fall apart once you realize how easy it is to fake a jawline with better leanness or a pump. Anecdotes and theories don’t equal evidence, no matter how many people repeat them. Course sellers and influencers push the idea because it monetizes hope, not because it’s real. Without controlled studies and actual data, the claim collapses.
What They Really Do
AAS and peptides can absolutely change how you look but they do it through muscle and soft tissue, not bone. Increased lean mass makes your traps, shoulders, and neck thicker, which frames the head differently and creates a stronger “halo” effect. Fat reduction and water manipulation sharpen your face, often giving the illusion of better bone structure. Some compounds can affect skin quality, vascularity, or even hair growth, which further alters the impression your face gives off. But these are surface-level changes, not skeletal changes. The underlying bone is exactly the same, it’s just hidden or revealed differently depending on body composition and soft tissue. That’s why the “body halo” is real and noticeable, but the fantasy of growing new bone is not. Understanding this difference keeps expectations realistic.
if your end goal is real skeletal change in the face, the only effective options are surgery and orthodontics. Orthognathic surgery, maxillary impaction, mandibular advancement, and similar procedures can physically reposition or reshape bone, which is something hormones simply cannot do once you’re an adult. If you’re only aiming for a better physique, then AAS can help.
