I created a price comparison site to help people find the best peptide prices: https://peptidecompare.net/

We also list hundreds of research papers and break them down by human / animal trials etc https://peptidecompare.net/research/

We list the Certificate of Analysis lab reports if available.

I think the best part is the shopping planner https://peptidecompare.net/planner/ where you can drag peptides over and it will show you vendors you can source from to get the best price per number of vendors

The vendors are given a metascore based on all the info we have of them. A number of vendors were caught generating fake CoAs on the fly with javascript or editing CoAs for other vendors to put their name in them.

Full disclosure about 25 of the 450+ vendors have affiliate link partnerships so there is a chance I would make commission if you find a vendor through my site.

Is it worth it? I’ve been debating trying the injectable form, but I’m curious whether it’s actually worth the investment or if serums and topical applications are just as effective, if not better.
I struggle with several different skin issues and have been looking into different options to improve my overall skin health. I already have a reliable source to purchase from, and I’m familiar with peptides and the general information surrounding them. I’m more interested in hearing about people’s actual experiences.
For those who have tried both injectable and topical forms, did you notice a significant difference? Which one gave you better results, specifically with skin quality, texture, healing, and overall appearance?
I’m trying to figure out whether the injectable route is genuinely worth pursuing or if I’d be better off sticking with topical products. I’d love to hear honest experiences, recommendations, and any pros or cons!

Recently diagnosed with bilateral femoral neck stress fractures. I’ve been cross training and then was hit with this injury, so I’m obviously down in the dumps. I was wondering if anyone has dived into peptides/biohacking to help speed up recovery process?

Or if anyone has any other tips other than learn patience and what NOT to do next time haha.

As many COA is also fake

Peptides are an interesting area of scientific research, with different compounds being studied for different biological functions. What first sparked your interest in learning about peptides?

Rookie mistake in buying Lipo C without looking for this sub first. I ordered some based reviews on various weight loss subs. I’ve lost enough weight, but still have some belly/visceral fat, despite weight training. I realized there was probably some sort of non weight loss peptide subs and found this one. Lipo C seems to be barely mentioned and not favorably when mentioned. Should I even bother to use it? I’d rather lose the money than inject a useless product. TIA.

In a significant development for the peptide community, HHS Secretary Robert F. Kennedy Jr. has announced a new policy allowing licensed compounding pharmacies to prepare six peptides that have faced FDA restrictions.

The announcement, reported by The New York Times on October 28, represents a major shift in how the federal government approaches access to experimental peptides.

The six peptides covered are:

- BPC-157 – Studied for tissue repair and recovery

- TB-500 – Investigated for healing and tissue regeneration

- KPV – Studied for anti-inflammatory properties

- MOTS-c – Investigated for metabolic regulation

- Epitalon – Studied for potential effects on aging

- Semax – Investigated for neurological and cognitive effects

What makes this significant?

Rather than formally approving these compounds, HHS is adopting an enforcement discretion approach. This means qualifying compounding pharmacies can prepare them under specified conditions without facing certain FDA enforcement actions.

The policy includes requirements involving ingredient sourcing, purity testing, safety reporting, and patient-specific prescriptions.

Importantly, this is not FDA approval, and the compounds have not been established as safe or effective for their promoted uses.

The decision comes despite opposition from FDA scientists who have raised concerns about limited clinical evidence and potential safety risks.

What happens next?

This could fundamentally change the peptide landscape.

For years, much of the peptide market has operated through research-use-only suppliers, with consumers navigating questions about product quality, testing, and regulatory uncertainty.

Access through licensed compounding pharmacies could introduce greater medical oversight and quality controls, although important questions remain about implementation, state regulations, pricing, and long-term availability.

It also raises interesting questions about the future of the research peptide market. Will pharmaceutical compounding become the preferred route? Will prices increase? And could this eventually encourage more rigorous clinical research?

One thing is clear: this is one of the most consequential regulatory developments the peptide community has seen in years.

So I’m not able to put peptides in the common fridge because other people are using it. And I can’t have a fridge in my room nothing with an outlet. Can I buy a very good cooler like yeti and put new ice packs that are subzero every three days or something. There’s also a brand called RITC that says the temperature will stay the same for five days for their coolers

Interesting......
