Estimated amount active from your doses and each ester’s half-life. Shape and timing, not a lab result.

Why MyoStats
A workout app plus a food app runs about R380 ($23) a month, and neither tracks a cycle or reads your bloods. MyoStats does all of it for R39 (≈ $2.37) a month, or R26 (≈ $1.59) a month billed yearly: cheaper than any of them.
