GH Peptide Questions

I am a 29 year old male, 6’0 around 195lbs. Over 3 years, I have lost 100lbs using just diet and exercises maintaining a calorie deficit and strength training (plus cardio). I have not done a full body dexa scan but have a scale that estimates (I think it’s probably bullshit but I figured I’d directionally correct and moving in the right direction it’s good enough). The scale says I am about 22% body fat, but I realistically think probably closer to 26%.

In the last 3 weeks, I recently started Reta (0.5mg twice a week) just to help with some of the food noise (realistically, it helps me focus more at work without the constant hunger). Also I have done pretty lose dose of Glow to help with some injuries I have got over the last 3 years. I believe I am going so stop with that as it’s not improving and I have read about the side effects of long term use so want to only use as needed.

Once I get down to around 180-185 (I am shooting for early March as I am on an aggressive cut), I would start to use a GH peptide (likely CJC-IPA, and also MOTS-C). I have read the risks about GH peptides (related to potential tumour growth and cancer risk). I know it’s limited but does anyone have any recommendations for certain screens to do prior to taking these peptides? I used Chat GPT and it listed multiple different screens specific to certain cancers, but wanted to see if anyone had a practical example.

TLDR: thinking of doing a GH Peptide and am not sure which specific tumour screens or precautions to take. Also is a dexa scan worth it and how often should I re-evaluate that?
