Graded honestly, hype deflated
CJC-1295
A synthetic GHRH analog that tells your body to make more growth hormone. Half the GH stack, endlessly confused over 'DAC vs no-DAC,' and marketed as 'safe GH' — a phrase that's doing a lot of work.
Ipamorelin
A selective growth-hormone secretagogue, the gentle-reputation other half of the GH stack. 'Cleaner' than the older GHRPs — which people wrongly read as 'proven safe.'
TB-500
A synthetic version of part of the thymosin beta-4 protein, sold as BPC-157's recovery sidekick. Popular in horse racing before it was popular in gyms — which tells you where the evidence comes from.

Steroids, SARMs and secretagogues that target the same goal. Clearly tagged — same rules apply: we grade them, we don't dose them.
