Glutathione Protocols

Hi Guys I have been reading and seeing countless posts on social media for the health benefits of Glutathione and I would like to hear from people that are actually using it. What are the benefits you have seen / felt since starting? What protocol are you following the dosage and how often. I have been on GHK for the past 2 months 2mg a day 5 days on 2 days off and my skin has never looked better. I guess im wondering what additional Glutathione brings to the table Thanks guys

Male Fertility and HCG

Husband (age 39) has been on trt for about three years ( he takes a fairly small dose) it makes him feel amazing. However, we do know it causes infertility in men and we are wanting to start a family soon. He does have a child from a previous relationship so we do know that he is fertile however, that was eleven years ago and before trt.

After doing some research it sounds encouraging that HCG may be the answer. I am trying to look into HCG. He has been off trt for about a month now and feels TERRIBLE.

I have heard of some men being on TRT and HCG and finding success in getting their partner pregnant. Any success stories? Or how does HCG alone make a male feel?

Thank you

Anyone else notice the FDA's proposed use for some peptides has almost nothing to do with why we actually take them?

I was looking through the briefing docs for the July 23-24 PCAC meeting and something kept jumping out at me. It's not just that FDA is leaning toward keeping all seven off the 503A list, it's that the use case they're actually reviewing is often totally disconnected from why any of us are running these things.

Epitalon is the one that got me. FDA reviewed it for insomnia. That's it. Not telomeres, not longevity, not any of the anti-aging stuff that's basically the entire reason people know this peptide exists.

Same deal with BPC-157. The reviewed indication is ulcerative colitis specifically. Meanwhile pretty much nobody in this sub is running BPC for UC, it's tendons, joints, general gut and recovery stuff.

Semax was reviewed for cerebral ischemia, which is a stroke related use. Not exactly the same as running it for focus.

TB-500, KPV, MOTS-c, and DSIP line up a lot closer to their actual community use honestly, wound healing, inflammation, metabolic stuff, sleep.

I get why this happens, someone nominates a peptide for a specific indication and that's what gets evaluated, it's not really FDA's job to review "what biohackers are actually doing with it." But it does mean the review process and the actual demand driving this whole market are kind of talking past each other.

I wonder what you guys think. For whatever you're personally taking, does FDA's reviewed use match your actual reason at all, or is it not even close?

Ghk-cu not much improvement?

Is it normal that I feel like some days my skin looks great and other days I still experience dry patches, redness. I also still get occasional small breakout. I feel like I have only got more glowy skin? I’ve been taking it 5 days a week 2 days off for about 2 months

If you touch the plunger of the syringe , do you have to toss the peptide ?

If you touch the plunger during reconstitution, do you have to toss the vial?

I reconstitution using 1ml insulin syringe, small.

Because of the suction, I guided the plunger with fingers obviously.

Target was 2 ml, so pushed the plunger back in and drew another 1 ml BAC, and did it again.

It then occured to me that I might have introduced contamination on the plunger. I can't seem to find any posts on Reddit about this issue. I guess most people just use large enough syringes from the beginning.

Is it salvagable with a filter or ok without a filter? It's KLOW, expensive and difficult for me to get now

Ultimate peptide for soft tissue & joints elbow area...?

Is the glow or klow stack any better than Wolverine stack? If so & how? New to BPC157/TB500. I am hoping to do push ups again after so many years. I have had tennis elbow for ages now. I don't look forward to chest workout as it takes me 20-30 mins just to warm the elbow soft tissue area up.

Reta stomach pain/cramps

5’10 193.2 currently - started at 218lbs

I have been on Reta for 14 weeks now and just did my first 3mg week and have had really bad stomach aches in my upper stomach, Have also significantly noticed the sulfur burps. Prior to last week I haven’t had any noticeable side effects but had to drop back down to 2mg this week. I have been taking Pepto bismol to help with the pain.

Anyone have any ideas to why this happened? Or have had a similar experience?

Peptides and Claude/ChatGPT

Currently taking tirzepatide for my type 2 diabetes and it works great. Glucose is under control and the weight loss was a bonus. I started researching different peptides and decide to ask Claude what he thought.

I've shared my medical issues, blood pressure, lab numbers and he has given tremendous insight. Claude suggested stacks with some very reasoned data to back it up. Not sure I'm going to follow his advice but for anyone looking for more data, it was very informative - give it a try

FDA career staff say evidence is insufficient to expand peptide compounding, contradicting RFK Jr's push

Worth flagging for anyone tracking the July PCAC meeting. FDA career scientists posted a recommendation Monday saying there isn't enough evidence to allow certain peptides to be produced by compounding pharmacies, which contradicts Health Secretary RFK Jr's push to expand access to these products.

The recommendation went up quietly, around the same time HHS added several new members to the panel that will review some of these peptides next month.

The panel composition is the part I'd pay closest attention to. Earlier versions of the FDA's compounding panel were mostly academics from places like Duke, Harvard, and Johns Hopkins, and they voted against a string of peptide ingredients as too risky.

The new group instead includes more than half a dozen panelists who run clinics, online businesses, or pharmacies that specialize in peptides.

AP's reporting names specific examples, including a Florida clinic operator who sells peptide, vitamin, testosterone, and weight loss injections, and a panelist who charges for "peptide and hormone" consultations while promoting BPC-157 and GHK-Cu to a large social following.

So you've got career staff saying the science doesn't support reclassification, while the review panel itself is being staffed with people who have financial ties to the industry being reviewed. That tension is the story here, not just the staff recommendation on its own.

For context on the broader timeline: FDA is set to hold a two-day advisory committee meeting in late July to discuss seven peptides including BPC-157, with a second panel taking up five more peptides by February 2027.

The part of GLP-1s people don’t talk about enough

A lot of GLP-1 discussion is focused on the obvious stuff: appetite suppression, weight loss, food noise going quiet, and before/after results.

But I’m more interested in the parts people don’t always mention.

For example, some people say GLP-1s changed their whole relationship with food. Not just eating less, but not caring about food the same way anymore. For some, that sounds freeing. For others, it seems weirdly flat, like they lost a source of comfort or reward they didn’t realize they depended on.

There’s also the gym side. If appetite drops too much, getting enough protein and calories can become harder, and training can feel different. Some people seem to lose weight quickly but then struggle with energy, strength, or recovery if they’re not careful.

Then there’s the mental side: mood, motivation, alcohol cravings, impulse control, sleep, and even just how people structure their day when food is no longer the main thing they think about.

I’m not posting this as medical advice or to hype anything. I’m just curious about the less obvious parts.

For people who have researched or used GLP-1 programs, what surprised you the most that nobody really warned you about?

I just received TB-500, HGH and Reta (unsure if I am going to use it; I am not fat, just a little overweight this last year.

I have never used HGH before: any thoughts or insights?
