Peptide Sciences was great before shutdown — my results so far

Fair enough on the practical perspective. But "works great" isn't testable without singles as a comparison. How do you know the blend works as well as running tirz and sema separately? You don't have a control. I'm not saying the blend is bad — I'm saying the *uncertainty* is higher. For $9 more per injection ($38 blend vs $47 singles), you could buy singles and know exactly what dose of each peptide you're administering. The healing stack blend (BPC + TB) I'm actually more comfortable with because: 1. BPC-157 and TB-500 are structurally very different (15 vs 43 amino acids, no fatty acid chains on either) 2. Both are typically dosed in ranges rather than precise targets 3. The cost savings are proportionally larger ($24 blend vs $30+ singles) Has anyone tested the healing stack blend?

I have the healing stack blend test data. Ordered 10 vials at $24 each. Sent one to Janoshik: - BPC-157: 4.8mg detected (96% of label claim) - TB-500: 1.9mg detected (95% of label claim) - Combined purity: 98.1% Both components right where they should be. The slight shortfalls are within normal analytical variance for Janoshik's method. Been running this blend for 4 weeks for a chronic tennis elbow issue. Reconstitute with 1mL BAC water, draw 0.2mL 2x daily. That gives me roughly 960mcg BPC and 380mcg TB per injection. Pain has gone from constant to intermittent. Grip strength improving. For the healing peptides, I think the blend is a no-brainer. The convenience and cost savings outweigh any marginal concerns about inter-peptide stability.

This thread has been exactly the discussion I needed. My takeaway: - GLP-1 blend (Tirz+Sema): Proceed with caution, slight underdosing concern on sema component. Fine if you're not sensitive to exact sema dosing. Singles preferred if dosing precision matters. - Healing blend (BPC+TB): Looks solid based on testing. Good value proposition. Comfortable ordering. I'm going to grab the healing blend for an ongoing knee issue and stick with individual tirz vials for my weight management protocol. Best of both worlds. Thanks everyone — this is why this forum exists.

Adding to the collective data: QSC also has a "GH Boost" blend (Ipamorelin 5mg + CJC-1295 no DAC 2mg) for $28/vial. I tested it: - Ipamorelin: 4.7mg detected (94% label) - CJC-1295: 1.85mg detected (92.5% label) - Combined purity: 96.9% Slightly lower accuracy than the other blends discussed here. The CJC component especially seems to run light. Could be that CJC-1295 is more susceptible to degradation during the blending/lyophilization process. My general rule: the more complex and sensitive the peptides in the blend, the more I'd lean toward singles. Simple peptides (BPC, TB) blend fine. Acylated peptides (tirz, sema) blend with caveats. Modified GHRHs (CJC) seem to take a hit in blend format. Your mileage may vary.

92.5% label claim on CJC is pushing it for me. That's meaningful underdosing. Thanks for the data though — this is exactly why we test. Community note: if you're ordering blends from QSC (or any vendor), please test and share results. We need more N values to determine if these shortfalls are systematic or batch-dependent. Single test results are anecdotes; a pattern of results is data.
