This is a lie. You physically don’t just pick up where you left off. Nice try
To put this in perspective, and it is a bit strange, I have only seen one, maybe two cases, where someone has reached sexual maturation after a stunted puberty.
In PED hormone circles, it's a frequent question if you can grow 'down there' with hormones. The only time anyone has had success was a kid who had his puberty stunted from an opioid addiction, via HCG and something else I think. I think this dude was one in a million, he was young and I think was prescribed it to treat his hypogonadism. This was not a BLOCKED puberty, and if reversing that were possible it would likely require absurd amounts of GH, like the amount given to GH deficient children to replicate the natural production during growing up normally, meticulous dosing of DHT, testosterone, all that stuff and more, just to have a
hope of returning to a baseline that they should be at anyways.
In short, you can never go back from those drugs and it's the parents or, God forbid, a groomer, who do this to kids.
