Ultrasound and skinfolds: operator dependence in practice Replied, post #75 · Outcomes › Body composition · 25 Jul 2026 · 9 likes Comparison to published data: the trials reported mean fat and lean mass changes. Individual results vary around that mean. Being above or below average is not a sign…
Here for the analytics and not much else Replied, post #83 · Lounge › Introductions · 24 Jul 2026 · 0 likes I read post #81 twice before replying, because I had assumed the opposite. No judgment: people come to this community from all backgrounds and with all motivations.…
Follow-up: How compounding permissions changed when supply normalised Replied, post #44 · Sourcing › Regulatory · 20 Jul 2026 · 31 likes post #43 answers the question as asked.

Practical note that does not fit anywhere else. Whatever you conclude from this topic, write down what you did…
Coming back to: A community side-effect dataset, with its response rate and biases Replied, post #93 · Data & Tools › Datasets · 9 Jul 2026 · 2 likes Worth separating two things that post #89 runs together.

Reconstituting a multi-strength kit without mixing yourself up — what changed since Replied, post #31 · Practice › Reconstitution · 23 Jun 2026 · 0 likes Coming back to post #29, because the follow-up matters more than the original answer. The decimal-point error: computing 5 mg / 2 mL as 0.25 mg/mL instead of 2.5 mg/mL…
