Five clinically-grounded tools we use with every client on a peptide, GLP-1, or longevity protocol. Run your numbers, then let a licensed provider fine-tune the full picture.
All-in-One Snapshot

BMI Calculator
Body Mass Index, the standard clinical screen for weight-related health risk and the first check for GLP-1 eligibility.
BMI 27 to 29.9 qualifies for full-dose GLP-1 when paired with a weight-related condition, hypertension, prediabetes, sleep apnea, high cholesterol, or PCOS. Microdosing is also an option.
Not a fit
Microdose*
Microdose
Std + comorbid
Standard dose
*Microdose GLP-1 = sub-therapeutic weekly dosing (e.g. sublingual semaglutide + B12, or low-dose tirzepatide) used off-label for metabolic health, appetite regulation, and inflammation, not FDA weight-loss dosing.
BMI is a starting point, not a prescription. Eligibility, standard dose or microdose, is determined by a licensed medical provider after a full intake including history, labs, meds, and goals.
Total Daily Energy (TDEE)
How many calories your body actually burns each day. The foundation number every protocol builds on.
TDEE = your estimated daily calorie burn. Eat at this number to maintain, below to lose, above to build. Feed this into the Calorie Deficit calculator below.
Calorie Deficit
Turn your TDEE into a realistic weekly loss target, without slipping into muscle-losing under-eating.
Sustainable deficit is 0.5 to 1% of body weight per week. On a GLP-1, appetite drops naturally, the risk is under-eating and losing muscle. Pair with the protein target below.
Protein Target
Muscle is the organ we're protecting on peptides and GLP-1s. This is your floor, not your ceiling.
Peptide protocols (CJC/Ipa, MOTS-C) and GLP-1s both work better with a high-protein base. Muscle is the metabolic organ you're protecting. Building? Protein climbs to 1.25 to 1.75 g per lb, you can't add tissue you never ate.
Macro Nutrient Calculator
Personalized protein, carb, and fat targets, protein scales with your goal, from 0.8 g per lb cutting up to 2.0 g per lb of desired bodyweight when you're building.
Desired bodyweight (Devine): 130.7 lb → you're at 1.1 g / lb = 144 g protein. On GLP-1s or in a cut, stay at the top of the range to protect lean mass.
GLP-1 protocols (our Ultimate Stack: Tirzepatide + B12, or Semaglutide) plus AOD-9604 and MOTS-C for stubborn adipose and metabolic conditioning.
Protein grams are calculated from your ideal bodyweight, not what you weigh today, so the target stays realistic whether you're 30 lb over or right at goal. Never drop below 1,200 kcal without provider oversight.
Water Intake
Personalized daily hydration in oz, cups, and liters, tuned to bodyweight and activity.
GLP-1s slow gastric emptying and blunt thirst cues. Constipation and fatigue on tirzepatide/semaglutide are almost always under-hydration. Front-load early.
