The results are starting to come in. For those just joining: there's been a debate in the peptide community about whether research-grade tesamorelin should be stored at room temperature or refrigerated after reconstitution. Instead of arguing theory, I partnered with Freedom Diagnostics to run an actual degradation study. Here's how it works: We took two identical samples of reconstituted tesamorelin. One stays at room temperature. One goes in the fridge. Both get tested once a week for four weeks. Initial baseline results: - Sample 1: 99.24% purity - Sample 2: 99.25% purity Essentially identical starting points — exactly what we need for a fair comparison. I've attached the original COA so you can see the data for yourself. Over the next four weeks, we'll track whether purity holds, drops, or differs between the two storage methods. No speculation. Just numbers. Big shoutout to Ion Peptides for providing the samples for this study. I'll post updates each week as new results come in. Appreciate everyone following along — this is how we get real answers.

This post is for research and educational purposes only — not medical advice and not intended for human consumption. Modern Aminos just added a full line of dissolvable strips to their site, and honestly, the pricing is noticeably better than what we've seen from other vendors carrying them. I grabbed a few to check out — Melanotan II, CJC-1295 + Ipamorelin, and the Selank + Semax strips. Before I get into the unboxing, let me give you some context on why dissolvable strips are interesting — and where the limitations are. How Dissolvable Strips Work These are sublingual strips — you place them under your tongue and let them dissolve. The idea is that the peptide absorbs through the thin tissue under your tongue directly into the bloodstream, bypassing your digestive system entirely. That means no stomach acid breaking it down and no liver first-pass metabolism chewing through it before it ever reaches your system. Sounds great in theory. But there's a catch — and it comes down to molecular weight. Research shows that sublingual absorption drops off significantly once a compound exceeds about 500-700 Daltons. The larger the molecule, the harder it is to passively diffuse through that sublingual tissue. So let's look at what we're working with here: Selank — 751.89 Da — Right at the edge. Selank was originally designed for intranasal delivery in Russia, so mucosal absorption is already part of its design. A sublingual strip is a similar concept — thin mucosal tissue, direct to bloodstream. Of the peptides I'm unboxing, this one makes the most sense for this delivery method. Semax — 813.92 Da — Slightly larger than Selank but still in a reasonable range. Same story — originally an intranasal peptide, so it's built to absorb through mucosal tissue. Pairing it with Selank in one strip is a smart move. Melanotan II — 1,024.2 Da — Now we're above 1,000 Da. At this molecular weight, sublingual absorption is going to be lower than subcutaneous. It's a cyclic peptide, which gives it some structural stability advantages, but size is still working against it here. You'll likely need to manage expectations compared to traditional administration.

We all know the feeling — you research and immediately go "yep, that one's spicy." 🌶️ These are the most common ones I hear about from the community and from my own experience. Some of these are just known for having that burn, especially certain blends and standalone compounds. Which of these sting the most for you? Drop a comment if I missed any — these are just the most common ones off the top of my head. Curious to see which ones hit the hardest for you guys. 👇

I mentioned this last week, but Valor just made a meaningful change to their lyophilization process. A lot of you were running into issues where bacteriostatic water would squirt back out during reconstitution, or the water wouldn't pull into the vial the way it should with a properly vacuum-sealed peptide. Their new chemist added a step at the end of the process — after nitrogen sealing, they now heat the vials to ensure they still pull a vacuum just like a standard vacuum-sealed peptide would. Simple fix, big difference. In this video, I reconstitute two different Tesamorelin 32mg vials side by side so you can see the difference for yourself: - The vial with the X on the label is the old version (before the process change) - The clean label is the new version with the updated lyophilization step Watch the full video to see how differently the water behaves between the two. It's a noticeable improvement. This is the kind of stuff that matters — when a vendor actually listens to feedback and makes changes to improve their product. Good on Valor for addressing it. 🔥 Valor Peptides Sale is LIVE I mentioned Valor was finalizing their sale details a couple days ago, and it's finally live!

Check them out here: https://modernaminos.com/product-category/dissolvable-strips/?ref=derek Now — I do want to address something directly. We all remember what happened with Modern Aminos and the GLP-1 situation back in December. I'm not going to sugarcoat that. But here's what I will say: they called me directly and said, "We got duped." No regulatory spin. No finger-pointing. No "it was out of our hands" nonsense. They owned it. It was credit card processors telling them that all of this GLP-1 stuff was going away — and they acted on that bad information. In fairness to every other vendor on the platform, I have not put their GLP-1s back up on PeptidePrice.store, and I don't plan to. That's a matter of consistency and fairness across the board. But I do respect accountability. In this space, too many people deflect, disappear, or blame somebody else when things go sideways. Modern didn't do that. They picked up the phone and were straight with me, and that matters. This doesn't erase what happened — but it does factor into how I evaluate a company moving forward. Dissolvable strips are a different product category entirely. I do value what Modern Aminos brings to the table across the board with different product categories. That's why they've been a key player in the industry for so long
