It’s that time once again! 🧼🫧
Thanks you all for your participation and continued support.

We’re excited to share something Troy and Marina have been working on — OSG BioLabs is officially live.

OSG BioLabs was created to make research peptides easier to understand, with clear information, transparent testing, and a straightforward look at what different compounds are being studied for.

Check out the new site at:

OSGBioLabs.com

Real Science. Real Potential.

OSG BioLabs is a separate business from Obsidian Strength. For research use only.

OSG BioLabs is officially online.

If you’ve been curious about peptides but didn’t know where to start, the new site should make it a whole lot easier.

We’ve spent a lot of time putting this together so people can actually understand what these research compounds are, what they’re being studied for, and how products like GHK-Cu, GLOW, KLOW, BPC-157, TB-500, MOTS-C, NAD+, GLP-1/2/3 and others are different.

The goal was simple: clear information, quality research compounds, transparent testing, and real people you can reach when you have a question.

Many of you know Troy’s shoulder surgery was a major one. This is part of the story that ultimately led him and Marina down the path of learning more about peptide research and eventually creating OSG BioLabs. Pretty cool to see where that journey has taken them. 💪

If you know Marina, you know how important health and fitness have always been to her. Her own experience and curiosity about peptide research became another part of what eventually led Troy & Marina to create OSG BioLabs. Here’s a little bit of her story. ❤️

MARINA'S GHK-Cu JOURNEY

When Marina moved to the U.S. from Argentina in 2023, she started noticing a significant change in the health of her hair, skin and nails.

Her hair became noticeably drier and more brittle. Her nails became weaker and broke much more easily, and she noticed changes in her skin as well.

Was it the climate? The water? The environment? The difference in the quality of the food and what goes into our food here in the U.S. compared with Argentina?

Probably some combination of things — but the difference after moving here was noticeable.

Over the past few months, Marina has been using GHK-Cu to see what kind of difference it could make in the health and appearance of her hair, skin and nails.

The results she's experienced have been fantastic.

Her hair is noticeably thicker, healthier and less brittle. Her fingernails are stronger and no longer seem to break nearly as easily. She's also noticed a significant improvement in the overall appearance and quality of her skin.

Then came something we weren't expecting.

On a recent trip back to Argentina, Marina visited her dermatologist — someone who had seen her before and knew what her hair and skin looked like previously.

Her dermatologist noticed the difference too and essentially told her:

“Whatever you're doing, keep doing it. It's working.”

That's pretty powerful when someone who hasn't seen you in a while notices the change without being told what to look for.

Marina's experience with GHK-Cu has been a big part of our growing interest in peptide research and ultimately our decision to create OSG BioLabs.

It's her personal experience, and everyone's experience can be different. But the changes she's seen have certainly made us want to learn more.

The proof is in the photo!!!

You've probably been hearing a lot more about PEPTIDES lately.

So have we.

Obsidian Strength owners Troy & Marina have spent considerable time learning about the rapidly growing world of peptide research.

That interest ultimately led them to create OSG BioLabs — with the goal of providing a trusted, reliable source for peptide research products right here in our local area.

From body composition and recovery research to energy, performance, hair and skin — peptides are getting a tremendous amount of attention.

Over the next several weeks, we'll be sharing more about what Troy & Marina have learned, their personal experiences, and the science behind different peptides.

OSG BioLabs is a separate business from Obsidian Strength. All OSG BioLabs questions and inquiries should go directly to Troy & Marina/OSG BioLabs rather than gym staff.

Stay tuned. There's a lot to talk about.
