Seen quick results (not long-term, huge sustained growth) in just a few days. Over the medium-term, ie, 8-12 weeks, got ripped and looked great even eating suboptimally (pretty shitty diet-wise, actually). It's just nuts how you can inhale calories so long as protein intake and carbs are high, you'll look good. Felt great pretty immediately also, for me, I had improved sleep quality, skin brighter/healthier, felt like oxygen/inhaling while training or not was invigorating if that makes sense. This was 4iU 5 on 2 off of usually Rip IIRC and some bluetops which still worked but seemed less 'pure.' In terms of negative sides, I started to get carpal tunnel over a month in, got a comment or two on my nose looking bigger (lmao). I did an experiment where I implemented some plans/concepts from DatBTrue's Forum a while ago involving peptides + GH and it added a little bit to the gains. In terms of performance, it seemed like I was more explosive after cycling off AAS but staying on GH even while doing PCT I had speed-strength.
