Peptide myths that won't die

'GH peptides increase GH naturally so there are no side effects.' False. Elevated IGF-1, water retention, insulin resistance are all real. Natural ≠ consequence-free.

'Subq dose is the same as IM dose.' The pharmacokinetics differ. For a lot of compounds it matters.

'You need to cycle BPC.' No actual evidence for this. The cycle-everything mindset gets copy-pasted from AAS culture and doesn't always apply.

'Bloodwork doesn't matter if you feel fine.' This one kills me. You can feel fine with ApoB at 140. Feeling fine is not a diagnostic.

^ preach.

'IGF-1 at the top of the range is optimal.' Top of range in a 25-year-old reference is not the same as optimal for a 45-year-old. Context collapses under a single number.

'More is better because the receptor desensitizes anyway.' That's a lazy read of pharmacology and it's getting people dosed into oblivion.

'GLP-1 microdosing gives you all the benefits with none of the side effects.' It gives you fewer side effects and correspondingly less of the benefit. The math still has to math.

'I know it's working because I feel it immediately.' Most peptides have a delayed mechanism. If you feel something in 20 minutes, that's pharmacology or placebo — usually the latter.

'Every rat study translates to humans 1:1.' No. Rat half-life, rat dose-response, rat endocrine system — not yours.

'GH fasting is required or it won't work.' Mild insulin blunting is real, but 'required' is too strong. The data is thinner than the forum consensus suggests.

'If it's not FDA-approved it's unsafe.' Also 'if it's not FDA-approved it doesn't work.' Both are wrong for opposite reasons.

'Reconstitute with bac water and it lasts forever.' Bac is stable for ~28 days and a peptide in solution degrades on its own schedule. Forever is generous.

'Natural test production is protected on peptide-only cycles.' Depends what you're running and how hard. CJC+ipa low dose, sure. Heavy GHRP daily for a year, less sure.

'You can just copy any protocol from a podcast.' The protocol was designed for the guy telling the story. Not for you.

'Anecdotes from 4 people = consensus.' Sample size of 4 isn't a trend, it's a coincidence.

OP edit — keeping a running list. Thanks all. This is a good reference thread to link the next time someone asks 'but I read on Reddit...'

The BPC thing is valid but I'd push back on the "it's just a tool" framing. Yeah it's not magic but if it genuinely speeds up tendon recovery by months that's pretty close to magic for someone dealing with a chronic injury. Way more useful than most people give it credit for. The podcast protocol thing is real tho, seen too many dudes run someone else's stack and wonder why they got sides the original guy never mentioned.
