Questions if these are decent LoR

[Josh70]

To start off I am not very good at asking for LoR. I haven't asked for a single one these have just been offered to me so far. My first one is from a former boss where I worked as a pharmacy technician and I also did a internship there for my school. The letter is from the pharmacy director of the hospital so wonder if that is a decent letter.

My next one is from a professor that really likes me only problem is they are just an adjunct professor who only has a master degree but they will write me a very good letter.

My last one is from the lab manager at my school who does hold a PhD though so wonder if that will be a good letter.

One of my LOR writers was not a PhD, and 2 were CC instructors. One of the programs I interviewed with had problems with this (one of the interviewers told me they liked the letters to be from people they knew), and maybe some of the programs I applied to but was not interviewed by did too, I don't know. However, I am certain that all 3 of my LORs were critically important in getting me accepted to the program I will be starting in September. I was a non-traditional applicant,and I asked people who knew me well and who supported me and encouraged me as I worked toward my goal. I am sure they all wrote me fantastic letters. I also applied to life science programs. All I can say is that it will depend on the personal prejudices of your admissions committees, but to me your choices seem decent. You have people who will be able to talk about your lab experience and your potential to do research, and that seems to be what's most important.

What are you applying for? Is it an MA or a PhD? Research-heavy programs or more professional?

Did your internship involve any research? How about the work you did for the other profs who mention?

If it's a PhD program a LOR from someone who only has a Masters degree will count less, because that person will have less knowledge about what it takes to go through PhD training and certainly no first hand experience, so their opinion regarding your potential to succeed is less founded. Similarly, if none of these LORs can directly address your research skills, that's a problem for a research-based program. But given that you outlined three options and most schools require three LORs, I'm not sure I understand what the dilemma is, unless you have other options.
