Halotestin mogs every compound for bone dimorphism and it’s not even close (No medical advice!)
halotestin (fluoxymesterone) is literally the most potent androgen receptor agonist you can put in your mouth.
AR binding potency:
- halo: 19x testosterone
- tren: 3-5x testosterone
- dht: 3x testosterone
- hgh: 0x (doesnt even bind AR lmfao)
source: saartok et al., j steroid biochem 1984
now why does this matter for dimorphism? because skeletal sexual dimorphism (wider jaw, brow ridge, broader frame) is driven by PERIOSTEAL APPOSITION. thats new bone being laid on the OUTSIDE of existing bone. and guess what activates osteoblasts on the periosteum? ANDROGEN RECEPTOR ACTIVATION. not estrogen. not gh. AR.
callewaert et al 2010 showed male periosteal bone formation is 70% higher than female during puberty. vanderschueren (endocr rev 2004) confirmed androgens via AR are the primary driver. vandenput & ohlsson (2014, PMC3955330) showed androgens promote cortical consolidation and maintain cortical thickness through periosteal apposition specifically.
why halo mogs tren:
tren is 3-5x test for AR. halo is 19x. simple math. but it gets worse for tren. tren is progestogenic which suppresses endogenous test AND estrogen. you actually NEED some estrogen for bone mineralization. tren nukes it. halo doesnt aromatize AT ALL (c11β hydroxyl blocks aromatase) but it also doesnt suppress e2 the same way. plus halo inhibits 11β-HSD2 (odermatt et al toxicol sci 2012 PMID 22273746) which blocks cortisol inactivation in bone tissue. tren doesnt do this.
net result: halo is roughly 4-5x more potent than tren for dimorphic bone remodeling
why halo mogs hgh:
this is where most of you are coping the hardest. “just run gh bro” gh/igf-1 drives LONGITUDINAL growth and overall bone SIZE. it does NOT create sexually dimorphic bone geometry. callewaert 2010 showed igf-1 knockout mice have ZERO skeletal sexual dimorphism. gh makes bones bigger. androgens make bones MALE. completely different mechanism. hgh is maybe 0.5x testosterone for dimorphic remodeling because it only works indirectly through igf-1 on general bone size not periosteal width.
halo is roughly 8-10x more potent than test, and functionally 15-20x more effective than gh for Dimorphism specifically
For comparison:
testosterone — 1x
tren — 3-4x
hgh — 0.5x
halotestin — 8-10x
these are mechanistic estimates from receptor binding data and non-aromatization advantage. no direct head to head clinical trial exists. but the pharmacology is clear.
before you retards run to your source:
halo is 17alpha alkylated. it will destroy your liver. hdl goes to zero within 2 weeks. its a potent 11β-HSD2 inhibitor so your blood pressure will be through the roof. cardiotoxic at literally any dose. if youre still growing it will fuse your plates FASTER and you will be shorter. this is not a recommendation. this is pharmacology.
tldr: halotestin has 19x the AR potency of test, AR drives periosteal bone apposition which IS skeletal dimorphism, it doesnt aromatize so theres no estrogenic brake on bone widening, and it mogs tren by 4-5x and test by 8-10x for dimorphic bone remodeling. hgh doesnt even compete because it drives size not shape. its also hepatotoxic poison so dont take it (or if you do, do it at your own risk).
