Question Well Actually ×9 Slow Clap ×2

Week 8 update. 4kg down from the start, muscle cramps basically gone since about week 60.

Things that worked: consistency, protein at breakfast, walking more than I want to. Things that did not: everything I bought on the internet to help with muscle cramps.

The part that surprised me is how much of this is admin. Ordering, storing, logging, remembering. Nobody mentions that the hard bit is not the drug, it is the routine.

Happy to answer anything. Please do not ask me what dose you should be on.

The practical rule people converge on is 28 days at fridge temperature after first puncture, and that comes from the preservative, not the peptide.

Mechanistically the bit that matters is dead space. It explains most of the early profile and a decent chunk of the outcome.

stopper coring on the 24th draw because you keep using the same entry point. rotate.

the concentration on the vial in marker is the most important step

more water means more units for the same dose, which means finer resolution

u-100 syringe, not u-40, or your math is off by factor of 5

What was the vial size and how much bac water?

The single most useful thing I did was write the concentration on the vial. Stopped all the confusion after that.

swirl, do not shake, or you are courting oxidation

This is correct. 3mL versus 18mL is the common mistake.

About c/reconstitution

The arithmetic and the technique. Bacteriostatic versus sterile water, reconstitution volume as a concentration choice, converting mg/mL into insulin-syringe units, dead space, swirl-not-shake, stopper coring, and how long a reconstituted vial is actually good for. Math errors get corrected fast and politely.

c/reconstitution rules
  1. Show your numbers. "How many units?" with no mg and no mL cannot be answered.
  2. Never post a calculation as advice without stating the concentration it assumes.
  3. No sterile-compounding-for-others discussion. Personal handling only.
  4. Independent community. Nobody here sells anything, and anyone who tries is banned.
  5. Not medical advice. Describe what you did; never prescribe to a stranger.
  6. Claims need evidence. Batch numbers, dated screenshots, independent test reports, or a citation.
  7. No referral links, discount codes or affiliate URLs. Permanent ban, no appeal.
  8. No contact handles, wallet addresses or tracking numbers — they identify people.
  9. Be recognisably decent. Disagree hard, insult nobody.
