Stats: 5'-10", 215lbs (97.5kg)

Symptoms: Chronic lifter elbow, wrist pain, shoulder pain, and now knee pain. All symptoms exhibited when lifting. Used to have poor form and ego lifted, but have corrected and still suffer from symptoms. PT alone doesn't seem to provide any progress.

Intended Stack: BPC157 and TB500

My questions:

1. Based on research, I am reading my dosages should be 250mcg bpc/day. Should this be once a day at 250mcg for the injection or 500mcg for two injections at 250 mcg each?
2. Based on research, I am reading my dosages should be 5mcg-20mcg/week injected 2/3x a week. After 2 weeks, 1/2 the dose and reduce to 1x injection a week. Am I on the right track here?
3. For reconstitution, the peptide calculator indicates that more of the BAC water results in a higher mcg dose. How does this not dilute the concentration? How much BAC water should be used for the reconstition of BPC vs TB500?
4. Does the type and size of insulin needle used matter?
5. I've reach everything from 12 week cycle to 4 week cycle. Which is best based on symptoms and goals? What is the best combination of vials to purchase to make this the most economical use of bulk discounts while keeping the appropriate cycle time in mind?
