- Different administration methods produce vastly different taste exposure profiles. The table below compares five common approaches based on taste intensity (1 = minimal, 10 = severe), convenience, and bioavailability impact.
- Size 00 gelatin capsule
- 1–2
- Low. Requires scale and empty capsules
- None. Standard 60–70%
- +10–15 minutes (capsule dissolution)
- Gold standard for taste avoidance; adds minimal cost and complexity
- Raw powder with water
- 9–10
- None. Direct consumption
- None
- No delay
- Maximum taste exposure; non-compliance risk high
- Powder in cocoa mixture
- 5–6
- Medium. Requires mixing, measuring
- Possible minor delay from fat content
- +5–10 minutes
- Practical compromise when capsules aren't available
- Sublingual holding
- 10
- Low. Direct mucosal contact
- No advantage; possibly reduced
- Worst method. Intensifies taste with no bioavailability benefit
- Honey/nut butter suspension
- 6–7
- Medium. Requires thorough mixing
- Possible delay from fat/sugar matrix
- +10–20 minutes
- Reduces contact but may affect absorption kinetics; inconsistent results
- Capsule administration consistently outperforms all alternatives for MK-677 oral taste management. The 10–15 minute delay in plasma concentration onset is clinically irrelevant for a compound with 4–6 hour half-life and effects that accumulate over days to weeks. Users who report capsule failure typically experienced contamination during handling. Even trace powder on fingers transfers to lips and tongue during swallowing.
